Dakota Digital BIM-22-2 Manuals

MAN#650598 BIM-22-2 Bus Interface Module for TPMS (Tire Pressure Monitoring System) This Bus Interface Module (BIM) communicates with a TPMS Receiver Module which receives tire pressures and other information from four TPMS sensors installed in a vehicle’s tires. There are three interface (I/O) ports on the module. Two of these can be connected to a Dakota Digital instrument system or to another BIM, allowing several units to be daisy chained together. Do not connect these I/O ports to anything other than a Dakota Digital control box or BIM. Ensure all BIM units are connected properly. On appropriate VHX, VFD3, and VFD3X systems, use the BIM-XX-1 harness (not shown). On HDX and other VHX, VFD3, and VFD3X systems, use the BIM-XX-2 harness. The interface labeled “INPUT” on the BIM-22-2 is connected to the TPMS Receiver Module using the TPMS Receiver Module adapter harness. The TPMS sensors transmit pressures and other information wirelessly through an RF signal. They are to be mounted inside the vehicle’s tires; replacing normal valve stems. We recommend that the tires be rebalanced after TPMS sensors are installed. Do not mount the BIM-22-2 and TPMS Receiver Module in the engine compartment; they should be mounted in the interior of the vehicle. The BIM-22-2 should be installed in a location where its display and switch are accessible in the event a new TPMS sensor needs to be installed in the system (see BIM Learn Sensors Mode). In situations where TPMS reception is not adequate inside the interior of the vehicle, the weatherproof TPMS Receiver Module can be mounted outside on the chassis near the center of the vehicle for better reception of the RF transmission signals from the TPMS sensors. The BIM-22-2 system provides tire pressures in PSI (pounds per square inch) for each of the vehicle’s four tires to a control box. When the vehicle is first turned on, dashes will be displayed on the gauge until the sensors have activated or “woken up” from their sleeping state. The sensors wake up by driving the vehicle or if a pressure change of at least 2 PSI has taken place. This behavior of going to sleep when the vehicle is not moving vastly prolongs a sensor’s battery life. After the sensors wake up, they report pressures to the TPMS Receiver Module, which in turn are reported through the BIM-22-2 to the control box.

MAN#650600 HDX QUICK START GUIDE FOR BIM-22-2 - TPMS (Tire Pressure Monitoring System) This guide is designed to get you up and running quickly with the BIM-22-2 on an HDX system. It provides a brief installation explanation as well as a step-by-step Locate procedure for finding the sensors’ positions after a tire rotation has taken place. This BIM-22-2 communicates with a TPMS Receiver Module which receives tire pressures and other information from four TPMS pressure sensors installed in a vehicle’s tires. It then provides this information for displaying on an HDX instrument system.  Do not mount the BIM-22-2 and TPMS Receiver modules in the engine compartment; they should be mounted in the interior of the vehicle. In situations where TPMS reception is not adequate inside the interior of the vehicle, the weatherproof TPMS Receiver Module can be mounted outside on the chassis near the center of the vehicle for better reception of the RF transmission signals from the TPMS sensors.  The BIM-22-2 should be installed in a location where its display and switch are accessible in the event a TPMS Sensor needs to be replaced (See BIM Learn Sensors Mode in the section Special Operating Modes of the BIM-22-2 owner’s manual).  Connect the BIM-22-2 to the HDX control box using the BIM-xx-2 18 inch power/data harness.  Connect the BIM-22-2 to the TPMS Receiver Module using the TPMS Receiver Module adapter Harness.  Install the TPMS sensors in the vehicle’s tires to the locations indicated by their marked colors (LF = Red, RF = Green, LR = Blue, RR = Yellow).
