Is Your GM Vehicle Experiencing Strange Electrical Problems?
The Body Control Module, or BCM, is the central nervous system for your vehicle’s comfort and security features. It manages everything from your power windows and door locks to the interior lights, security system, and even the wipers. When the BCM starts to fail, it can cause a cascade of confusing and frustrating electrical issues that can be difficult to diagnose. You might experience intermittent problems that come and go, or a complete failure of multiple systems at once.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security system engaging randomly, causing a no-start condition.
- ✔ Warning lights on the dashboard, such as the airbag or security light.
- ✔ Wipers, radio, or climate controls working intermittently or not at all.
- ✔ A parasitic battery drain that leaves you with a dead battery.

Installation and Post-Install Notes
Installation is straightforward for those with some mechanical experience. Once installed, most functions should work immediately. However, depending on your specific vehicle, a couple of additional steps may be required:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
