Restore Full Functionality to Your Vehicle’s Electronics
Are you battling bizarre electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are common indicators of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s proper operation and your peace of mind.
We take the guesswork and hassle out of the repair process. Unlike a standard replacement part that requires a trip to the dealership for expensive programming, this BCM arrives at your door pre-programmed with the latest GM software, specifically matched to your vehicle’s VIN. This plug-and-play approach saves you time, money, and the headache of coordinating with a service center.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Vehicle security system or keyless entry malfunctions.
- ✔ Horn sounding unexpectedly or not working.
- ✔ Warning lights on the dashboard with no apparent cause.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent no-start conditions related to the anti-theft system.

Installation and Post-Install Notes
While installation is straightforward for many, some vehicles may require additional steps to ensure all systems are synchronized. After installing your new GM Body Control Module, be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and interior chimes.
Is this BCM truly plug-and-play?
Yes, for most vehicles. Because we program it to your VIN, it does not require any initial setup at a dealership. However, as noted, some vehicles may require a simple relearn procedure for specific subsystems like the airbag or brake pedal sensor after installation.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will use this to load the correct GM software onto the module before shipping it to you.
What happens if my airbag light comes on after installation?
This indicates the BCM needs to be electronically ‘introduced’ to the airbag’s Supplemental Deployment Module (SDM). A qualified technician with a high-level scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
