Body Control Module (BCM)

The BCM is a multifunction module which monitors all sensor inputs and all CAN messages relating to the TPMS. The BCM records and retains the unique sensor identifier of each TPMS sensor.

The BCM retains the previous sensor location information following a tire rotation. For the BCM to learn the new sensor location, the sensors must be trained (calibrated) to the BCM. Refer to: Tire Pressure Monitoring System (TPMS) Sensor Location Calibration . Additionally, the sensors must be trained when a new BCM is installed.

When installing a new BCM, there are several procedures that must be carried out in order for the module to function correctly. These procedures include, but are not limited to; PMI, anti-theft parameter reset, programming keyless entry remote and setting customer preferences. Refer to: Body Control Module (BCM) .
