Introduction
CIRCUIT OPERATIONThe Body Control Module (BCM) used in this vehicle provides a communication interface with other controllers and modules. The BCM also controls various vehicle functions. Circuit operation of specific systems or components controlled by the BCM are found in wiring diagram section covering the component or system.
This section of the wiring diagrams provides an overview of the functions controlled or supported by the BCM. The BCM provides or supports the following features:
- A/C Select Switch Status
- Ambient Temperature
- Automatic Funeral Mode
- Automatic Headlamp Control
- Chime
- Courtesy Lamps with Time Out
- Door, Hood or Liftgate Ajar Status
- Door Lock Inhibit
- Electronic Odometer
- Electronic Vehicle Information Center
- Fog Lamp Control
- Headlamp Delay
- High Beam Indicator
- Illuminated Entry
- Instrument Panel Dimming
- Intermittent Wiper Control
- Liftgate Courtesy Lamp Disable
- Mechanical Instrument Cluster
- Rear Window Defogger Control
- Remote Radio Control
- Seat Belt Reminder
- Speed Sensitive Intermittent Wipe Control
- Vehicle Theft Security System
The BCM communicates with the following controllers and modules over the CCD bus:
- Automatic Temperature Control (ATC) Module
- Compass (Overhead Console)
- Driver Door Module (DDM)
- Mechanical Instrument Cluster
- Memory Seat Module
- Passenger Door Module (PDM)
- Powertrain Control Module
- Vehicle Information Center
- Radio
Circuit A250 from fuse 11 in the Power Distribution Center (PDC) powers circuit F75 through fuse 7 in the junction block. Circuit F75 supplies battery voltage to the BCM. Circuits Z1 and Z2 provide ground for the BCM.
