Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with bizarre and frustrating electrical issues in your 2002 GMC Yukon, Sierra, Silverado, or other compatible GM vehicle, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central nervous system for your vehicle’s body electronics, controlling everything from your power windows and locks to your interior lights and security system. When it starts to fail, it can cause a cascade of problems that are difficult to diagnose.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ “Service Electrical System” or similar warnings on the dash.
- ✔ Diagnostic scan tools being unable to communicate with the module.

Important Post-Installation Information
While this BCM is pre-programmed for your convenience, some vehicles may require additional steps after installation to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installing the new BCM, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary. This requires a professional-grade diagnostic tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed. This ensures your brake lights and traction control system function as intended.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic features, such as power windows, locks, lights, wipers, security system, and instrument cluster functions.
Is this part truly plug-and-play?
It is as close as it gets. We program the module to your VIN before shipping, so it will work with your vehicle’s specific options. However, as noted, some models may require a simple relearn procedure for the airbag or brake systems, which can be done by a qualified technician.
How do I provide my Vehicle Identification Number (VIN)?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information to program the module correctly.
What if my airbag light turns on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag system (SDM). A repair shop with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
