Description
The Body Control Module (BCM) is located behind the glove box. The BCM controls many electrical components and
systems for the vehicle electrical system. The BCM is the primary hub that controls functions such as internal and
external lighting, power windows and power door locks.
Operation
The Body Control Module (BCM) uses hard wired inputs from various sensors and switches. The sensors and
switches are located throughout the vehicle.
The following components are inputs to the BCM:
•Key switch
• Rear defroster switch
• Hazard lamp switch
• Power window switches
• Power door lock switches
• Seat belt switch
• Vehicle speed
• Door ajar switches
• Turn signal switch
The following components are outputs from the BCM:
• Key lamp
• Stop lamp relay
• Rear defroster grid
• Courtesy lamps
• Power window motor
• Power door lock motor
• Turn signal lamps

DTC Confirmation Procedure:
Before performing the following procedure, confirm that battery voltage is more than 12 V.
• Turn ignition switch off.
• Connect the X-431 scan tool to the Data Link Connector (DLC) - use the most current software available.
• Turn ignition switch on, select view, record and erase DTC.
• Start engine and warm it up to the normal operating temperature.
• Select view DTC and data stream.
• If the DTC is detected, the condition is current. Go to Diagnostic Procedure - Step 1.
• If the DTC is not detected, the DTC condition is intermittent (See Diagnostic Help and Intermittent DTC Trou-
bleshooting in Section 15 Body & Accessories for more information).
•
NOTE :
• Inspect the vehicle for aftermarket accessories that may exceed the Generator System output.
• Inspect the fuses. If an open fuse is found, use the wiring schematics as a guide and inspect the wiring and
connectors for damage.
• Troubleshoot any Engine Control Module (ECM) charging/cranking DTCs before proceeding.
NOTE :
While performing electrical diagnosis & testing, always refer to the electrical schematics for specific circuit
and component information.
