Experiencing Strange Electrical Problems in Your GM Vehicle?
If your vehicle is suffering from erratic power windows, flickering lights, malfunctioning door locks, or a security system that won’t disarm, a failing Body Control Module (BCM) is the most likely cause. The BCM acts as the central nervous system for your car’s body electronics, and when it fails, it can create a host of frustrating and difficult-to-diagnose issues. This replacement Body Control Module is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft light stays on, preventing the engine from starting.
- ✔ Dashboard warning lights appear and disappear randomly.
- ✔ Key fobs stop working or work intermittently.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication errors with other vehicle modules when using a diagnostic scan tool.

Installation and Post-Install Notes
Installation is typically straightforward, involving disconnecting the battery and swapping the old module with the new one. However, depending on your specific model, a couple of additional steps may be required after installation:
- Airbag System Sync: If your 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 vehicles may require a brake pedal position sensor relearn to ensure correct operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Is this part truly plug-and-play?
Because we program it to your VIN, it is plug-and-play for most of the BCM’s core functions like starting the engine, and operating lights and locks. However, as noted, some models may require simple relearn procedures for systems like the airbags or brake sensor.
What happens if I install this without programming?
An unprogrammed BCM will not work in your vehicle. The vehicle’s anti-theft system will activate, and it will not start or run. Our pre-programming service is essential for proper function.
Where is the BCM located on my vehicle?
The location varies. On many GM cars like the Impala or Acadia, it’s behind the driver’s side dash. On Express and Savana vans, it’s often in the center dash area. On trucks and SUVs like the Tahoe, it’s typically found under the steering column.
Do I need to send my old BCM back?
No. This purchase does not require a core return. You can keep your old module.
