Is Your GM Vehicle Plagued by Baffling Electrical Problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. When it begins to fail, it can cause a cascade of frustrating and seemingly unrelated issues. From flickering lights and malfunctioning power windows to a car that won’t start, a faulty BCM can make your vehicle feel unreliable. This isn’t just an inconvenience; it can be a serious safety concern. Don’t let a failing module dictate your driving experience. Take control back with a reliable, VIN-programmed replacement.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing no-start conditions or the alarm to go off randomly.
- ✔ Dashboard warning lights (like ABS, Airbag, or Check Engine) illuminating for no reason.
- ✔ Wipers or the horn activating on their own.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.

Simply provide us with your vehicle’s VIN during checkout, and our technicians will program the module with the latest GM-certified software specific to your car. This ensures that it communicates perfectly with your vehicle’s other systems right out of the box. This service saves you a trip to the dealership and the high cost of programming fees.
Installation and Post-Install Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems are synchronized. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on 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: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and more. It acts as a hub for these electronic features.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your vehicle’s specific options and configuration. This ensures a seamless installation and proper function without needing a trip to the dealer for programming.
Is this a plug-and-play part?
For most vehicles, yes. Because we pre-program it to your VIN, it eliminates the most difficult step. However, as noted, some models may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a professional scan tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Will this fix my ‘Service StabiliTrak’ or ‘Traction Control’ light?
A faulty BCM can sometimes cause these warnings. While this part may resolve the issue, these warnings can also be triggered by other components like wheel speed sensors or the steering angle sensor. Proper diagnosis is always recommended.
