Body Control Module: Initial Inspection and Diagnostic Overview
Body Control Module (BCM)
DTC List
The Body Control Module (BCM) uses information from other systems in order to execute some functions. Therefore, before further diagnosis, review
the general information on how the BCM computer system operates and how each system interacts with the BCM. This will save diagnostic time, future
misdiagnosis, and unnecessary parts replacement.
Use a scan tool in order to diagnose the BCM when referred to in diagnostic procedures. In addition to displaying Diagnostic Trouble Codes (DTCs), the
scan tool displays the input status and the data values used. The BCM also cycles many of the systems on and off. Any of these features can be selected
using the scan tool.
Become very familiar with the BCM capabilities and diagnostic features. These self-diagnostic features are referenced in the DTC tables and are very
useful in diagnosing non-DTC setting malfunctions as well.
