Step-by-Step Diagnostic Procedure
-
Attempt to communicate with the BCM using a scan tool.
-
Check the BCM connector (usually behind the dashboard or kick panel) for corrosion or water damage.
-
Measure bus voltage at the BCM connector (should see approximately 2.5V on CCD bus lines).
-
Inspect the bus wiring between the BCM and the diagnostic connector for damage.

Check for water leaks near the BCM location, especially from windshield seals or door drains.
Frequently Asked Questions
What does the BCM control?
The Body Control Module manages interior lighting, power windows, door locks, wipers, remote keyless entry, and other body electrical functions.
Can I drive without BCM communication?
Yes, but many convenience features will not work. The engine and transmission will operate normally since they are controlled by the PCM.
Is water damage a common cause?
Yes. BCMs on Chrysler vehicles are often located in areas prone to water intrusion from leaking windshield seals or clogged drain tubes.
