Is Your 2002 GM Truck Experiencing Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange warning messages on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable issues. Don’t let a faulty module keep you from enjoying your vehicle. This is the direct-fit, reliable solution you need.
From the Diagnostic Bay
We had a 2002 Yukon XL come in with a classic case of BCM failure. The customer complained that the power door locks would cycle randomly while driving, the radio would sometimes not turn on, and the “Service 4WD” light was on intermittently. After confirming power and grounds were good, we diagnosed a faulty BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The installation was straightforward, and all the electrical gremlins were gone instantly. The customer was back on the road the same day, saving significant time and money.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights staying on, flickering, or not working at all.
- ✔ The security system or alarm engaging randomly or preventing the vehicle from starting.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Unresponsive key fob or remote entry functions.
- ✔ False warning lights, such as the airbag or brake light.

Installation and Post-Install Procedures
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While the physical swap is straightforward for a DIYer with basic tools, some vehicles may require additional electronic ‘handshake’ procedures 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: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function correctly.
We offer this part with no core charge. You can keep your original module.

Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We handle all the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready to be installed.
Where is the BCM located on my 2002 Avalanche or Tahoe?
The Body Control Module is located inside the cabin, under the driver’s side dashboard, typically attached to a bracket near the steering column.
What if my airbag light turns on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically synced with your vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is this part truly plug-and-play?
For many vehicles, it is. However, due to variations in vehicle systems, some models may require the post-installation procedures mentioned above, like the airbag sync or brake pedal relearn.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
Do I have to send my old part back?
No, there is no core charge for this item. You can keep your original BCM.
