Are you experiencing frustrating electrical issues in your 2002 GM truck or SUV? Flickering lights, malfunctioning power windows and locks, or a security system that acts on its own are common signs of a failing Body Control Module (BCM).

We had a 2002 Yukon XL come in with a laundry list of electrical gremlins. The owner said the dome lights would stay on, the driver’s side power lock wouldn’t work, and the radio would randomly shut off. We checked grounds and wiring harnesses for hours. Finally, we hooked up our high-level scanner and saw erratic data coming from the BCM. Instead of a costly and time-consuming trip to the dealer, we installed one of our pre-programmed modules. In under an hour, every single issue was resolved. The customer was thrilled to have his truck back to normal without the dealership hassle.

Installation and Post-Install Procedures
Installation is straightforward for those with basic automotive experience. The BCM is typically located under the steering column. After installing your new, VIN-programmed module, some vehicles may require simple relearn procedures. In most cases, the vehicle will operate correctly immediately. However, please be aware of the following potential requirements:
- Airbag System Sync: If the 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: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your original module without the hassle of returning it.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and climate control features.
Is this part difficult to install?
The BCM is located under the driver’s side dashboard, near the steering column. It’s a plug-and-play installation with a few electrical connectors. Most people with basic DIY skills can replace it in under an hour.
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 specific vehicle options. This ensures it works correctly right out of the box without requiring a trip to the dealership.
Do I need to send my old BCM back?
No. This part is sold with no core charge, so you are not required to return your old, faulty module.
What if my airbag light comes on after installation?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Will this fit my 2002 Chevy Tahoe?
Yes, this BCM is compatible with the 2002 Tahoe, Yukon, Yukon XL 1500, Suburban 1500, Avalanche 1500, Escalade, and Escalade EXT as long as the service number on your original part matches one of the compatible numbers listed.
