Body Control Module (BCM) Configuration Error
There's a configuration problem with the Body Control Module.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The Body Control Module, which controls things like lights and locks, thinks there's something wrong with how it's set up. It might not match what the car expects based on how it's been wired or programmed.
What the computer is actually seeing
The BCM sees a mismatch in its configuration data. It flags this when it detects an unexpected state in its inputs or settings.
What a healthy reading looks like
BCM should show no configuration issues when inspected; voltage levels for inputs from switches should be 0V (off) or between 5V to 12V (on).
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Check the vehicle's wiring harness and connectors going to the BCM for any visible damage or corrosion. If damaged, repair the connections and retest.
- 22. Inspect for any recent modifications or aftermarket installations that might affect the BCM's operation. If found, address these issues and retest.
- 33. Verify that the BCM's software is up-to-date. If not, perform an update and clear the code. Recheck the system afterward.
- 44. Use a scan tool to check for any related codes or BCM programming errors. If present, follow the manufacturer's repair procedures for those specific codes.
Common causes
- Faulty Body Control Module
- Incorrect wiring or connections
- Software update failure
- Aftermarket modifications or added accessories
- Corroded connectors or terminals
Typical repair cost
$$ - $$$ (depending on whether module reprogramming or replacement is needed)
