Body Control Module - Description

DESCRIPTION

The Body Control Module (BCM) is located in the passenger compartment, attached to the left cowl panel underneath the left side of the instrument panel.

The BCM utilizes integrated circuitry and information carried on the Programmable Communications Interface (PCI) data bus network along with many hard wired inputs to monitor many sensor and switch inputs throughout the vehicle. In response to those inputs, the internal circuitry and programming of the BCM allow it to control and integrate many electronic functions and features of the vehicle through both hard wired outputs and the transmission of electronic message outputs to other electronic modules in the vehicle over the PCI data bus.

BATTERY SAVE MODE

The BCM has a battery save mode. This provides the customer with the ability to conserve battery power when storing the vehicle for up to three months without losing radio and Powertrain Control Module (PCM) memory. This is an alternative to disconnecting the battery negative cable.
