Are you battling frustrating electrical problems in your 2002 GM truck or van? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). This vital computer is the central hub for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing issues. Restore full functionality and peace of mind with our pre-programmed BCM, a direct-fit solution for part number 15095334 and other compatible numbers.
We make the repair process simple. Unlike a dealership that requires towing and expensive on-site programming, we flash this module with the latest GM software updates specific to your vehicle’s VIN before we ship it to you. This means you receive a part that is ready for installation, eliminating a major step and getting you back on the road faster.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security light is illuminated on the dash, possibly preventing the engine from starting.
- ✔ Inconsistent or non-functional heating and A/C controls.
- ✔ Remote keyless entry (key fob) stops working.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ False warnings on the instrument cluster, such as ‘door ajar’.
Why Choose Our Programmed 2002 Silverado BCM?
This isn’t just a replacement part; it’s a complete solution. By programming the module to your VIN, we ensure it communicates correctly with the other computers in your truck, like the Engine Control Module (ECM) and Powertrain Control Module (PCM). This unit is a reliable and cost-effective alternative to a costly dealership visit. It is compatible with a wide range of GM vehicles from the era, making it a versatile fix for many owners.
Installation Note: On most trucks like the Silverado, Sierra, Tahoe, and Yukon, the BCM is located under the steering column. On vans like the Astro and Safari, it is typically found in the center of the dash. After installation, some vehicles may require additional relearn procedures. If the airbag light appears, a ‘Setup SDM Primary Key in BCM’ procedure is needed. A ‘Brake Pedal Position Relearn’ may also be necessary for proper brake light and traction control operation. These procedures require a professional-grade scan tool.
Compatible Part Numbers: 15063578, 15081796, 15095334, 19208537, DKAK, DPNU
Frequently Asked Questions
What does a BCM do on my 2002 Silverado?
The Body Control Module (BCM) acts as the brain for your truck’s non-engine related electronics. It controls functions like power windows, locks, interior lighting, the security system, HVAC controls, and the key fob.
Is this part truly plug-and-play?
It is as close as it gets. We program it to your VIN before shipping, so it’s ready to be installed. However, as with any module replacement, some vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be done by a technician with a capable scan tool.
How do I provide my VIN for programming?
After you complete your purchase, you can add your VIN to the order notes or simply reply to your order confirmation email with the 17-digit VIN. We cannot ship the module until we receive this information.
What if my airbag light is on after I install it?
This is a known possibility. It means the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool 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.
Will this fit my 2002 GMC Sierra?
Yes, this BCM fits a wide range of 2002 GM trucks and vans, including the GMC Sierra 1500, 2500, and 3500, as well as the Chevy Silverado, Tahoe, Suburban, and many others. Please check the detailed fitment list on this page to confirm your specific model.
