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 
la

beled “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.
