Is Your GM Vehicle Acting Possessed? The BCM is Likely the Culprit.
The Body Control Module (BCM) is the central command center for your vehicle’s electronic accessories. It manages everything from your power windows, door locks, and interior lights to the anti-theft system and key fob recognition. When the BCM starts to fail, it can create a cascade of bizarre and frustrating electrical problems that seem to have no logical explanation. If you’re dealing with intermittent issues that come and go, a faulty BCM is a very common cause.
From the Diagnostic Bay
We recently had a 2014 Chevy Cruze come into the shop with a list of strange symptoms. The radio would change stations on its own, the dome light would flicker while driving, and sometimes the car just wouldn’t start. The owner had already replaced the battery and alternator with no success. After checking the main power and ground circuits, we focused on the BCM. By cloning the data from his failing module to a replacement unit, we solved every single issue in one go. It’s a perfect example of how this single component can wreak havoc on a vehicle’s entire electrical system.
Common Symptoms of a Failing BCM
- ✔ Power windows, locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or refusing to turn on.
- ✔ Horn honking randomly or not working when pressed.
- ✔ “Service Theft Deterrent System” message appearing on the dashboard.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Key fob not being recognized, preventing you from locking/unlocking doors or starting the vehicle.
- ✔ False warning lights illuminating on the instrument cluster for systems that are working correctly.
- ✔ Wipers activating on their own or not working at all.

Important Post-Installation Information
While our BCM arrives ready for installation, some vehicle systems may require a recalibration or sync procedure after the module is installed. These are standard procedures and can be performed by a qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called “Setup SDM Primary Key in BCM” is necessary to sync the airbag system with the new BCM. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure the brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
