6 1 Important instructions and safety instructions This publication is meant for commercial vehicle workshop personnel with knowl- edge of automotive electronics. The document provides all the information required to install and set-up the Smart- Board. Carefully read all safety instructions in this document before you start performing diagnostics or you replace and set-up a device or other similar activities. These safety instructions must be observed to avoid personal injury or material loss. WABCO only guarantees the safety, reliability and performance of its products and systems if all instructions, notes and safety instructions in this document are ob- served. Before you perform any work on the vehicle (repair, replacing parts, diagnos- tics etc.), you must ensure the following: Only trained and qualified technicians are to perform any work on the vehicle. Make sure to follow the specifications and instructions of the vehicle manufacturer. Always comply with the company and national accident prevention guidelines and Health and Safety regulations. Wear suitable protective clothing when necessary. The workplace has to be dry, as well as sufficiently lit and ventilated. CAUTION Danger of injury due to vehicle rolling! Danger of injury by actuating the brake while work is being performed on the vehi- cle. – Make sure that the transmission is in neutral and the hand brake has been pulled. – Secure the vehicle against rolling with chocks. – Attach a clearly marked note on the steering wheel saying that work is being performed on the vehicle and that the brake must not be touched.

7 1.1 Measures for avoiding electro-static charge and uncontrolled discharging (ESD) Note during construction and building the vehicle: – Prevent potential differences between components (e. g. axles) and the vehicle frame (Chassis). Make sure that the resistance between metallic parts of the components to the vehicle frame is lower than 10 Ohm (< 10 Ohm). Connect moving or insulated vehicle parts such as axles electrically conductive with the frame. – Prevent potential differences between the towing vehicle and the trailer. Make sure that an electrically conductive connection is made via the coupling (king pin, fifth wheel, claws with pins), even with no cable connection. – Use electrically conductive bolted connections when fastening the ECUs to the vehicle frame. – Use only cable conforming to WABCO specifications or WABCO original cable. – Run the cable in metallic casing if at all possible (e. g. inside the U-beam) or behind metallic and grounded protective plating, to minimize the influence of electro-magnetic fields. – Avoid the use of plastic materials if they can cause electrostatic charging. Note during repair and welding work on the vehicle: – Disconnect the battery - if installed in the vehicle. – Disconnect cable connections to devices and components and protect the plug- ins and connections from contamination and humidity. – Always connect the grounding electrode directly with the metal next to the weld- ing position when welding, to prevent magnetic fields and current flow via the cable or components. Make sure that current is well conducted by removing paint or rust. – Prevent heat influences on devices and cabling when welding.

performance of haulage companies operations and reducing the costs of the vehi- cle fleet. By integrating a number of control and indicator devices in a single, easy-to-handle multifunctional system, the SmartBoard helps to make trailer vehicles safer and more effective. fig. 2-1: SmartBoard The SmartBoard combines the following functions: • Display of distance driven (operates without power supply from the towing vehi- cle) • Immobilizer operation • Brake lining wear indicator (in connection with WABCO BVA) • Current axle load indicator • Tyre pressure indicator (in connection with WABCO IVTM) • Display of diagnostics and system messages • Information on the operation of the electronic air suspension (in connection with Trailer EBS E) • Information on the operation of the lifting axle(s) • Operating the relaxation function • Operating the brake release function • Operating the road finisher brake • Indication of the vehicle inclination • Operation of the freely configurable GIO functions • Display of selected operating data (ODR) and the measured values of the brak- ing system It therefore serves as a universal information and control system for implementing efficient trailer vehicle operation. A SmartBoard can be used to replace the following separate display and control units: • Odometer Status • Brake lining indicator • Lifting axle and traction help switch • Axle load indication • ECAS control box and/or unit • Relaxation function • Brake release function • Road Finisher Brake

with a connection to Trailer EBS D or E. 2.1 SmartBoard for ADR (GGVS) vehicles WABCO have developed a new SmartBoard version that allows trailers that carry dangerous goods to take advantage of SmartBoard functions. A SmartBoard suit- able for GGVS vehicles is available under the product number 446 192 111 0. Operation of the SmartBoard is identical to the standard version. Some functions are restricted, however, due to the operation without a battery: • No date and time function is available. For this reason it is not possible to store messages. • The odometer reading of the Trailer EBS is displayed. The internal odometer is without function. • Information is displayed when the trailer is supplied with power. SmartBoard 446 192 110 0 SmartBoard for ADR vehicles 446 192 111 0 Table: 2-1: SmartBoard versions The fitting dimensions and cable connections are unchanged. The SmartBoard is installed in compliance with the approval certificate TUEH - TB 2007 - 132.00. The certificate can be obtained from the product catalogue INFORM on the Internet at www.wabco-auto.com by entering the product number or the index words “Smart- Board“ or “certificate“.

plays the data transmitted by Trailer EBS. The SmartBoard is connected to Trailer EBS. The tyre pressure monitoring system IVTM and the BVA (brake lining wear indicator) are connected to Trailer EBS and so transmit their data to the SmartBoard via the Trailer EBS. The odometer obtains information from the Trailer EBS. In order to operate the SmartBoard's internal odometer independently of the Trailer EBS D function (and also without an ABS plug connection to the towing vehicle), the SmartBoard must be connected directly to the wheel sensor via the Y-cable. This is not required if there is a connection to Trailer EBS E: the wheel sensor signal is transmitted to the SmartBoard even when not supplied with power from the towing vehicle. Control of the air suspension functions (e. g. lifting and lowering the lifting axle or the chassis/vehicle body) requires the Trailer EBS E to be configured accordingly. fig. 3-1: System configuration in combination with Trailer EBS D

3.2 System prerequisites The SmartBoard is a device used for operating the Trailer EBS. The range of SmartBoard functions therefore depends on the Trailer EBS version and on the in- stalled components. The WABCO System BVA is required, i. e. for indicating the brake pad wear. The SmartBoard detects the installed components automatically and shows the available functions as menu symbols. If the system or component from which information is to be retrieved or that is to be controlled by the SmartBoard is not available, the corresponding menu item or symbol is not displayed. The SmartBoard is used in combination with the Trailer EBS D or E as of genera- tion D Premium (480 102 014 0). The software version of the SmartBoard is shown in the menu (see page 32). A number of functions are not available in the ADR version of the SmartBoard (see chapter 2.1 "SmartBoard for ADR (GGVS) vehicles", page 9).

17 4.4 Functions The SmartBoard provides a wide range of functions that can be accessed via sym- bols from the main menu. The chapters below describe the various functions. The following rules apply: • If a system is not available and no information can be retrieved from it, the cor- responding menu symbol is not displayed. • When the vehicle is at a standstill, the values that were last saved are displayed. These may deviate from the actual values (e. g. the tyre pressure if a leak is present). For an overview of which functions are available in combination with Trailer EBS D or E, see chapter 3.2 "System prerequisites", page 11. fig. 4-4: Main menu 4.4.1 Odometer Status The odometer reading from the Trailer EBS and the SmartBoard is displayed in this functional group. Notation Description Note Odometer (internal odometer Smart- Board) The SmartBoard determines the mileage/kilometrage directly from the ABS sen- sor signal. • The option is only displayed after the SmartBoard has detected that an ABS sensor is available. • The distance counter functions even when the ISO con- nection is not plugged in. • Differences between Trailer EBS odometer and the in- ternal odometer occur due to: Driving without the ISO plug connection (TEBS not oper- ating, SmartBoard supplied by battery). Different tyre sizes and going around corners (TEBS computes the average wheel speed, the SmartBoard only records sensor c). • If the tyre settings stored in the SmartBoard are inconsis- tent with those of the TEBS, an exclamation mark is displayed in the odometer bar. Mileage/Kilometrage The total mile- age/kilometrage is recorded by the Trailer EBS modula- tor. Record since the Trailer EBS system start-up. Trip EBS Kilometre count with ISO supply connected. Can be reset via the diagnostic software.

18 Notation Description Note Trip km Kilometre count with ISO supply connected. Can be reset in the SmartBoard. • To reset, select the option "Trip km" and press . • Select "Yes" when the message "Reset trip km" appears and press . 4.4.2 Immobilizer The immobilizer is for reducing the risk of theft. The function can be activated or deactivated by entering a self-defined PIN key via the SmartBoard. Enabling A PUK is necessary for each vehicle for enabling the first time. This requires the document "PUK Access Code 813 000 049 3" with an individual voucher code. With this voucher code, you can apply for the PUK on the internet under www.wabco-auto.com/immobilizer. The job of the PUK is: • Releasing the immobilizer function in the TEBS E modulator • Defining / changing the user PIN • Master key, to also release the vehicle without a PIN The PUK is reserved only for the end user. Handle the PUK with care and protect it from access to third-parties and unauthorized persons. Store the PUK in a safe location. WABCO will not be held responsible for the loss or misuse of the PUK. – Select the menu .. – Please enter the PUK. – Define a PIN and enter it. – Re-enter PIN to confirm. � Upon successful release, a confirmation appears on the display. Operation Before deactivating the immobilizer, the park brake (red button of PREV) of the trailer must be activated. With Trailer EBS as of generation E2, the park brake of the tow vehicle must be activated when deactivating the immobilizer and brake pressure must be applied on the yellow hose coupling. If the PIN is entered incorrectly 5 times, the PIN entry can only be made again after a 10 second delay. Another incorrect entry will double the duration of the delay. Af- ter 20 incorrect entries, the function is locked and must be enabled again using the PUK. – Select menu . – Enter the self-defined PIN.

19 Button : Selecting numbers 0 … 9 Button : Jump to the next digit position. Button : Confirmation of input � After entering the correct PIN, a confirmation window appears. If the vehicle was been locked, the window "Activated immobilizer" appears. The driver is also notified of the activated immobilizer by a continuous flashing of the yellow warning light in the tow vehicle (with ignition ON). If the vehicle was been unlocked, the window "Deactivated immobilizer" appears. Activated immobilizer Deactivated immobilizer Emergency release function The "Emergency trigger function“ menu appears if the function is defined and acti- vated in the TEBS E modulator. The emergency release function is defined for three release procedures. After us- ing the procedure, deactivating the immobilizer is only possible after entering the PIN. After renewed PIN entry, the counter for the emergency release function is set up to three again. – Select menu . – Press the button for the emergency release of the vehicle. � A confirmation message appears. As long as the immobilizer is deactivated via the emergency release function, the respective icon disappears from the main menu. If the vehicle is stopped for a period of >60 seconds, the immobilizer is reactivated.

20 4.4.3 Brake lining wear indication (BVA) The status of the brake lining wear is displayed in this functional group. When the brake lining has reached the wear limit (2 mm residual lining thickness), the warning LED and the menu item for this functional group flash in the main menu. Messages are only output via warning LEDs and flashing menu items if the "Event LED" functions is activated (see page 33). Notation Description Note All brake linings have a resid- ual thickness of more than the 2 mm wear limit. At least one brake lining has reached a wear limit <2 mm (the wire of the end value indi- cation in the brake lining is worn through). Check the brake linings as soon as possible and replace worn brake linings. 4.4.4 Axle load indication Information on the axle loads is indicated in this functional group. For example: Semitrailer In addition, a message can also be shown in the display. The warning thresholds can be set in the SmartBoard. WABCO suggestion for a 3-axle semitrailer with 9 t axle load on each axle. • The initial warning threshold is to be set to a 8 t axle load: When there is an axle load of 8 t, the menu item "axle load" flashes in the display. The driver is informed that further loading is not advised. • The secondary warning threshold is set to 9 t axle load: When an axle load of 9 t is exceeded, the red warning LED flashes and the menu item "axle load" flashes in the display. The driver is informed of overloading (see chapter 4.5 "Output of messages", page 37). The SmartBoard is supplied with the initial and the secondary warning threshold both set to 15 t. The warning thresholds are therefore not activated.

21 Notation Size Configuration Total axle load Total of the separate axle loads. Trailer EBS D/E Modula- tor Axle 1 to axle n Axle loads of the separate axles. Trailer EBS E Modulator With drawbar trailers, the axle load information is only displayed if second pressure sensor is installed. In the case of semitrailers with lifting axle, the lifting axle must be connected to the Trailer EBS Modulator. 4.4.5 Tyre-pressure monitoring The tyre pressures for the individual tyres, the nominal tyre pressure, and the con- figuration is displayed in this functional group. The key is used to switch between the different tyres. The tyre symbol flashes if the tyre pressure is too low. If the tyre has a fault, the warning LED and the menu item for this functional group flashes in the main menu. Messages are only output via warning LEDs and flashing menu items if the "Event LED" functions is activated (see page 33). Notation Description Note Nominal pressure The nominal pressure is set in the parameters of the IVTM electronic con- trol unit. The value applies to a cold tyre. Currently saved pressure for the selected tyre. Warning when the battery of the selected IVTM wheel module is low. Only with wheel module II IVTM 1B The IVTM tire pressure monitoring system is no longer available for the latest vehi- cle designs. 4.4.6 Information Messages from available systems are displayed in this functional group. The fol- lowing systems are capable of message output: • Trailer EBS D and E • IVTM

22 Messages are only output via warning LEDs and flashing menu items if the "Event LED" functions is activated (see page 33). Current messages are displayed first, then the messages that are no longer cur- rent. When a current message is present, the menu item for this functional group flashes in the main menu and the warning LED also flashes. With the ADR version, the internal clock is not active. No time entries are made in the ODR operating data memory or the diagnostic memory. Notation Size Please note System System responsible for output of the message (example: TEBS E). The key is used to navigate through the differ- ent messages. Warning light status Status of warning light (current or no longer current message). There are current messages with a warning light symbol available. The fault must be rectified. Messages without a warning light symbol are not current (old) and are still stored in the diagnostics memory of the ECU. Date Date at the time of message output.

Lifting the rear axle: • Switch between automatic and manual modes by pressing the . • Manual activation/deactivation of manoeuvring aid by pressing . Set and save memory level 1. To save the current level as a retrievable memory level, press for 5 seconds. Set and save memory level 2. To save the current level as a retrievable memory level, press for 5 seconds. Activation and de- activation of stand- by opera- tion Select any function from the air suspension menu within 30 seconds after the ignition is switched off. The Trailer EBS E then goes into stand-by mode with level control when loading / unloading for the time period set in the parameters. If the operator exits the SmartBoard air suspen- sion menu, stand-by operation is cancelled pre- maturely. This function requires that stand-by operation is a parameter in the Trailer EBS E. 4.4.7.1 Manoeuvring aid, drawbar load reduction Manoeuvring aid OptiTurn™ The OptiTurn™ manoeuvring aid improves the capability of the truck-semi-trailer combination to travel around curves and traffic circles and to manoeuvre around loading ramps. Travelling on narrow streets, curves and traffic circles causes excessive tyre wear and damage to tyre edges on curbstones. The limited area around loading ramps also hinders the manoeuvrability of the tractor-trailer combination.

24 OptiTurn™ automatically detects tight curves and traffic circles and relieves or raises the third axle of the semitrailer. This decreases the turning radius of the trac- tor-trailer combination and improves manoeuvrability. The tyres also have less fric- tion on the street and damages to the tyre edges on curbstones are prevented. Af- ter travelling through the curve, the relieved or raised axle is put back down into its initial position again. OptiTurn™ can be an inexpensive alternative to steering axles. Using OptiTurn™: • Reduction of tyre wear and tyre edge damage • Improvement in manoeuvrability of the tractor-trailer combination • Easier travel around curves and traffic circles • Reduction in axle tension • In many cases is an alternative to steering axles Drawbar load reduction OptiLoad™ The OptiLoad™ drawbar load reduction automatically distributes the weight of the load on the supporting axles of the tractor-semitrailer combination without having to actually shift the load in the trailer. If a trailer load is to be distributed to multiple delivery addresses, the remaining load can become unevenly distributed on the semitrailer. This can exceed the per- mitted axle load of the tractor drive axle. OptiLoad™ redistributes the load with targeted changed air-pressures in the air bellows of the semitrailer to the tractor- and semitrailer axles without having to change the position of the load on the semitrailer. OptiLoad™ supports the driver in preventing an overload on the tractor drive axle this way. OptiLoad™ is designed for loads up to 24 tonnes and works independent of the speed. Preventing overloading the tractor drive axle helps with: • Preventing damage to the tractor drive axle • Decreasing of tyre wear • Avoiding overload fines Operation The menu for controlling the manoeuvring aid and the drawbar load reduction is called up via menu , menu point Manual control The SmartBoard is used as a switch in manual control. The function is activated or deactivated with the button. Notation Description Note Function: activated Function: deactivated Automatic mode not defined in Trailer EBS E1, mode-change not possible.

25 Controlling automatic functionality If automated functionality is activated in the Trailer EBS E1, the icon "Auto" will be shown in the menu in SmartBoard: The "Automatic" mode is activated or deactivated with the button. By pressing the button, the function can also be activated manually e. g. to actuate the OptiLoad function while the vehicle is at a standstill. The manually activated function is deactivated again if the shut-off values (speed or bellows pressure) defined in the Trailer EBS E1 are achieved or the ignition of the vehicle is started again. The symbols in the lower portion of the display do not show the current status, they show the function of the respective buttons located underneath. Notation Description Note Manually deactivate function (trip func- tion) in automatic mode Button : Deactivate auto- matic mode Button : Manual activation of the function (until achieving the defined speed or until ignition OFF) Manually activate function in automatic mode Button : Deactivate auto- matic mode Button : Manually deactivating function (until ignition OFF) Manually activate function (trip func- tion) with automatic mode switched off Button : Activate auto- matic mode Button : Manually deactivating the function Manually deactivate function with automatic mode switched off Button : Activate auto- matic mode Button : Manual activation of the function (until achieving the defined speed or until ignition OFF) 4.4.8 Relaxation function WARNING Risk of injury due to moving vehicle. – Make sure that no persons are in the trailer danger zone when actuating the relaxation function! – Attach a clearly marked note on the steering wheel that work is being per- formed on vehicle! During loading and unloading procedures of semitrailers, the axle assembly is stressed if the brakes are applied on the entire unit. If the handbrake is released af- ter the unloading process for example, the chassis can spring up suddenly be- cause the air suspension lifts immediately with the still full air suspension bellows and the lack of a load on the vehicle. The new relaxation function prevents the chassis from suddenly springing up.

26 The relaxation function is activated by switching on the function in the TEBS E1 modulator. The tension on the applied brakes is released with the respective actua- tion of the brake cylinder from the modulator. The brakes are released by side (semitrailer/central axle trailer) or by axle (drawbar trailer) for this purpose. Braking the vehicle is always performed at over 18 %, because the brake cylinder is used for releasing the vehicle. 4.4.9 Brake release function The service brake in the trailer can be released by actuating the functions and with the vehicle at a standstill. A typical application for this function is for vehicle trans- porters. In this case the length of the trailer is changed via a hydraulic tension strut for simple loading of the entire vehicle. When releasing the button switch, the brake is immediately ventilated again causing the brake to be applied. Requirements for the brake release functions • The parking brake in the towing vehicle is actuated. • The pressure on the coupling head "yellow" must be greater than 6.5 bar. The brake release function will be aborted when the pressure on the coupling head "yellow" drops. • The vehicle must not roll. The brake release function will be aborted at a speed V > 1.8 km/h. A TÜV certificate for the brake release function can be obtained from the product catalogue INFORM on the Internet at www.wabco-auto.com by entering the prod- uct number or the index words “SmartBoard“ or “certificate“. 4.4.10 Road Finisher Brake The road finisher brake serves to brake tipper body vehicles when operating be- hind road finishers. The tipper body vehicle with the asphalt is pushed forward by the road finisher. To prevent the vehicle from rolling away it is braked slightly (e. g. with 0.7 … 1.5 bar). Notation Description Note Function deactivated Button : Setting the nominal brake pressure Button : Activating the function

Pressure sensor calibration DANGER Rolling vehicle – Position the vehicle on an even surface and secure it against rolling away with brake wedges. – Only use approved devices to jack up and secure the vehicle. CAUTION Risk of injury due to brake actuation while working on the vehicle – Attach a clearly marked note on the steering wheel saying that work is being performed on the vehicle and that the brake must not be touched. The SmartBoard makes it possible to calibrate the pressure sensors for the axle load display of the Trailer EBS E (see chapter 4.4.4 "Axle load indication", page 20). This improves the precision of the axle load indication. The more precise the vehi- cle weight is determined and the pressure sensors can be calibrated, the more precise the axle load indication will be. With an incorrect calibration, the axle load indication also shows incorrect values! The brake pressure output is not affected by this calibration, in this case, the val- ues defined by the vehicle manufacturer apply.

35 The calibration is performed in three different load states (trailer physically laden). The exact vehicle weight must be determined using a calibrated scale. The calibration must then be performed again if air-suspension or Trailer EBS E modulator is replaced. Calibration points The greater the weight difference between the individual calibration points, the more precise the axle load is displayed. Calibration point "Partially laden" is op- tional and does not have to be performed. • Unladen • Partially laden (optional) In partially laden status, the vehicle weight should be centered between the ve- hicle weight in unladen and fully laden status. • Fully laden Prerequisites • Trailer EBS E1 with software version TE14013 • SmartBoard with software as of version SB010207 • With drawbar trailers, another pressure sensor must be installed on the axle that brakes via the 3rd modulator. While calibrating, the parking brake and the service brake must be released. Calibration on the semitrailer – Determine the weight of the semi-trailer on a calibrated scale in unladen, par- tially laden (optional) and fully laden status.

37 This function can be used to adjust the main menu and other configurations (e. g. the number of pole wheel teeth) to the current system configuration, when, for ex- ample, the SmartBoard is fitted intro a different trailer or a system is not applicable. For further information see chapter 4.6.2 "Configuration of the main menu", page 39. Information Description Note Automatic configu- ration of the main menu Adjusting the main menu to the current system configura- tion Ignition (terminal 15) must be switched on and the trailer vehicle must be supplied with power. 4.5 Output of messages The SmartBoard outputs messages optically. • The corresponding menu item flashes in the display. • The warning LED flashes according to the message type. fig. 4-5: Output of messages 1 Flashing menu item (e. g., for overloading in this case) 2 Red flashing warning LED Messages are only output via warning LEDs and flashing menu items if the "Event LED" functions is activated (see page 33). The warning LED is deactivated once a speed of 10 km/h is reached. It is activated again once the speed drops below 8 km/h. Messages are outputted for the following functional groups: • Brake lining wear (end point indication BVA) One or more than one brake linings have reached their wear limit.

38 • Axle load indication Loading exceeds the set limit value. When the first limit value is exceeded, the menu item "Axle load" flashes in the display. When the second limit value is ex- ceeded, the menu item "Axle load" and the warning LED flashes (only in the case of 15) in the display. • Tyre monitoring (IVTM only) A tyre pressure is outside the permissible range. • Vehicle inclination The parameterised trailer inclination is exceeded. • Messages A connected system is currently sending a diagnostics message. Diagnostic messages The messages displayed in the menu "Messages" are represented as combina- tions of numbers. These numbers can be translated into plain text by means of the "Diagnostics messages" listed in the appendix. The messages always consist of four elements: fig. 4-6: Example for the "Messages" menu 1 The system that triggered the message 2 Current message: yes/no 3 The component concerned 4 The type of fault In the example shown above, a message with the following content is displayed: "Fault 05 (fault type: "Supply line interrupted") has occurred at component 002 "Wheel sensor b“) of TEBS E. If it is not possible to easily remedy the fault using your own resources, the vehicle must be driven carefully to the workshop, or it must be repaired on the spot (e. g. where there are acute tyre problems).

39 4.6 Extended settings 4.6.1 Start Screen (Splash Image) The SmartBoard Diagnostic Software can be used to load one picture into the SmartBoard. This image is then displayed for one second when the software is started. A start screen template and a WABCO suggestion for editing the file is available for download at: www.wabco-auto.com . This file can be modified using suitable software. It is also possible to create your own start screen. The file must have the following properties: File properties Values File format: *.BMP (BMP = Bitmap) Image size: 128 × 64 pixels Shading depth: 2 bit (black / white) Table: 4-4: Start screen properties 4.6.2 Configuration of the main menu During start-up procedures for the SmartBoard and each time the menu item is called up, the main menu is adapted for the installed components (see chapter 3.2 "System prerequisites", page 11). • Any new components that the SmartBoard detects are immediately added to the display configuration. • If a component is no longer available, the last valid status is displayed - the component is not automatically hidden. The "Air Suspension" component is an exception in this regard because it is no longer available with the ignition OFF. If the lining wear indicator (BVA) or the tyre monitoring system (IVTM) is removed from the overall system, it is necessary to initiate an automatic configuration. The menu item must be used for this purpose (see chap- ter 4.4.14.4 "Auto Config", page 36).

40 5 Assembly and installation Prior to installation, retrofitting, or repair of the SmartBoard, ensure the fol- lowing instructions are observed: Only trained and qualified personnel may perform this work. Make sure to follow the specifications and instructions of the vehicle manufacturer. Always comply with the company and national accident prevention guidelines and Health and Safety regulations. When working on the brake system, the vehicle must be secured against rolling away. Wear suitable protective clothing when necessary. The workplace has to be dry, as well as sufficiently lit and ventilated. – Make sure that you install the ADR version (446 192 111 0) of the SmartBoard in ADR vehicles (see chapter 2.1 "SmartBoard for ADR (GGVS) vehicles", page 9). – Disconnect the power supply to the towing vehicle. Consider any risks with re- gard to the short circuiting of batteries in the vehicle see chapter 1.1 "Measures for avoiding electro-static charge and uncontrolled discharging (ESD)", page 7. – Select the appropriate wiring diagram according to your system configuration (see chapter 8.3 "Circuit diagrams", page 54). – Select an installation location on the frame that is easily accessible for the user and that can be reached by the planned connecting cable.

WABCO offers you a workshop-suitable, impact- and contamination-resistant lap- top. This "Toughbook" with preinstalled Diagnostic Software can be obtained from WABCO. The Diagnostic Software will run on all standard PCs with an operating system Mi- crosoft Windows 2000 or higher however. There are no other special requirements of the hardware. The PC should however have a free USB connector or a free serial connector (COM interface 9-pin) to con- nect the diagnostic interface. Diagnostic Interface Set To set up the diagnosis, the WABCO Diagnostic Interface Set with order number 446 301 030 0 (USB connection) is required. The set contains the Diagnostic Inter- face and a USB connecting cable to the PC or laptop. The old Diagnostic Interfaces with serial connection (446 301 021 0) and with USB connection (446 301 022 0) can still be used. 6.3 Diagnostic Software There are three ways to obtain the Diagnostic Software: • Offline as a USB stick version • Online as a single download • As a part of a WABCO system diagnostics subscription For the diagnosis of multiple WABCO systems, WABCO offers you four different Diagnostic Software subscriptions via the Internet. These contain numerous diag- nostic programs at one very low price. On the Internet, on Web page www.wabco-auto.com in the quick access area, click on "Diagnosis" and then on "WABCO System Diagnostics". There, you will find fur- ther information and can order the Diagnostic Software in your language and to load onto your PC.

With diagnostic software "SmartBoard" (WABCO number 246 301 609 0), the SmartBoard can be configured to customer specifications. 6.4.1 Parameter setting The parameter settings dialogue is opened via the "System" menu item. fig. 6-1: Dialogue "Parameter Settings" The following settings can also be made in the parameter definitions. • In the menu, the language package A or B can be selected (see chapter 4.4.13 "Language", page 28). • To save these settings in the SmartBoard, select the button. • The settings can also be saved in a parameter file on a PC. To save the settings in a file, select the button . • A parameter file previously saved in this way can be loaded into the dialogue by selecting the button . • The same button is used to generate a parameter protocol.

The menu item from the menu can be used to update the operating software of the SmartBoard. The software is provided in the form of a file. This file can be selected using the button . The button must be selected to start the download. Only official operating software approved by WABCO can be downloaded into the ECU. In the event that the download is interrupted, it can easily be started again at a later point. However, the ECU will not function until the download has been completed successfully. The vehicle is then not permitted to be used on public roads. 6.4.3 Download of the "Splash Image" The PC Diagnostics provides a dialogue for writing any desired flash image to the ECU. For instructions and requirements for creating the file, see chapter 4.6.1 "Start Screen (Splash Image)", page 39. – Open menu item from the menu. – Select splash image using the button .

2 K-line (ISO 14230) 3 Ground 4 Wheel-speed sensors (IGM) 5 Wheel-speed sensors (IG) 6 CAN high (ISO 11989) 7 Supply connection (electrical) 7.2 EBS parameters This function permits the transfer of parameter settings from one Trailer EBS Modulator into a new modulator of the same type. This facilitates replacing a defec- tive modulator (see page 31). The following conditions apply here: • Trailer EBS D (Premium) and Trailer EBS E (Standard and Premium) are sup- ported. • The modulator that is to receive the parameter settings must be new. (Definition new: odometer reading <1 km and no initial start-up has yet been performed) If this requirement is not met, the menu is not available. • Only modulators with identical part numbers, software versions, and parameter versions may be the source / target for the parameter settings. If this requirement is not met, the message "Modulator not compatible" appears. • The parameter set is read out from the modulator automatically. This takes place after the modulator has been commissioned (EOL test performed by cus- tomer). The parameter set will not be automatically read out and stored in the Smart- Board unless the commissioning test (EOL test by customer) has been carried out. • The parameter set is read out automatically only once. Subsequent changes are not taken into account. To take those into account, the parameter set must be read out manually using the function . The commissioning test must be performed after the parameter set has been read into a modulator. The vehicle must be taken to a WABCO Service Centre as soon as possible for this purpose.

Not available in ADR version 446 192 111 0 The battery is designed to have an average life of five years; this may not be at- tained, however, if it is subjected to extremely frequent use with an unhitched trailer. When the battery only has 10 % of the original charge left, the "Battery almost empty" indication is displayed for one second after the start logo and the disclaimer appears for one second after the device is switched on. If the battery voltage is no longer sufficient to operate the internal real-time clock, the menu is greyed out. It is then no longer possible to transmit the time via CAN, i. e. the ODR data of the Trailer EBS E can no longer be saved together with the time. The internal odometer reading also does not function. 7.4 Replacing the battery (not applicable for ADR version 446 192 111 0) The SmartBoard has a replaceable battery. The battery status can be accessed via the menu . If the capacity of the battery is depleted, the SmartBoard can only be used if it is powered from a power supply provided in the towing vehicle. A replacement of this battery must be performed by an authorised specialist work- shop. A repair kit (No. 446 192 920 2) is available for this purpose; it describes the work steps in detail. Also see the spare part sheet on the Internet at www.wabco- auto.com under the menu item INFORM. Batteries are hazardous waste. Dispose of hazardous waste in an environmentally friendly manner and in compli- ance with relevant national regulations. 7.5 Care and Cleaning Use only a damp cloth to clean the SmartBoard. Never use cleaning agents. Detergents and other chemicals can damage the display and the keyboard and must never come into contact with the SmartBoard.
