BODY CONTROL MODULE - LHD





BODY CONTROL MODULE

The Body Control Module (BCM) (1) is concealed in the engine compartment inside of the Control Module Box (2) located next to the battery (3).

The BCM utilizes integrated circuitry and information carried on the Controller Area Network (CAN) bus along with many hardwired inputs to monitor many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal circuitry and programming of the BCM allows it to control and integrate many electronic functions and features of the vehicle through both hardwired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the CAN data bus.

The BCM for this model is serviced only as a complete unit. A BCM can only be repaired by or replaced through an authorized electronic warranty repair station. Refer to the latest version of the Warranty Policies and Procedures manual for a current listing of authorized electronic repair stations.

CONTROL MODULE COOLING FAN

The Control Module Cooling Fan is used to decrease the heat that is generated by the Transmission Control Module (TCM) and the Audio Amplifier. The Control Module Cooling Fan is located inside of the front lower section of the Control Module Box. The Cooling Fan is wired to the BCM and is activated when the ignition is On. The Cooling Fan is attached to a flexible duct that runs down to the passenger foot well, and circulates air to the modules. The fan is used to cool the modules that are mounted in the passenger compartment.
