BODY CONTROL MODULE
WARNING: To avoid serious or fatal injury on vehicles equipped with airbags, disable the supplemental restraint system before attempting
any steering wheel, steering column, airbag, seat belt tensioner, impact sensor, or instrument panel component diagnosis or service. Disconnect
and isolate the battery negative (ground) cable, then wait two minutes for the system capacitor to discharge before performing further
diagnosis or service. This is the only sure way to disable the supplemental restraint system. Failure to take the proper precautions could result
in accidental airbag deployment.
The hard wired circuits between components related to the Body Control Module (BCM) (also known as the Signal Acquisition and Actuation
Module/SAM) may be diagnosed using conventional diagnostic tools and procedures. Refer to the appropriate wiring information. The wiring
information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out
information and location views for the various wire harness connectors, splices and grounds.
However, conventional diagnostic methods will not prove conclusive in the diagnosis of the BCM or the electronic controls or communication between
modules and other devices that provide some features of the BCM. The most reliable, efficient, and accurate means to diagnose the BCM or the
electronic controls and communication related to BCM operation requires the use of a diagnostic scan tool. Refer to the appropriate diagnostic
information.
