Body Control Module (BCM)
The BCM is a multifunction module that monitors all sensor inputs and all HS-CAN messages that relate 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 to the BCM. Refer to TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING - INTELLIGENT ACCESS (IA) or TIRE PRESSURE MONITORING SYSTEM (TPMS) SENSOR TRAINING - INTEGRATED KEYHEAD TRANSMITTER (IKT) . 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. For a complete list of procedures to be performed, refer to Body Control Module (BCM) - Removal and Installation in MULTIFUNCTION ELECTRONIC MODULES .
