body control module (BCM)

The following are the ACC System functions provided by the BCM:

• The BCM provides a translating gateway for the high speed serial data circuit.
• The BCM reads all cruise control switches and the gap switch. The DSCC module monitors a variety of user operated switches from the BCM switch status information sent via the serial data circuit.
• The IPC illuminates the brake light based on a serial data message from the DSCC module during automatic braking.
• The BCM measures the brake pedal position and sends brake pedal travel status via serial data circuit to the ECM. The ECM disengages the ACC System when the brake is applied by the driver pressing the brake pedal.
• The BCM serves as a gateway to the display systems, instrument panel cluster (IPC), DIC and amplifier, visual and audible warnings. The BCM will generate visual and audible warnings based on high speed serial data messages from the DSCC module.
