Are you battling frustrating electrical gremlins in your GM truck or van? A faulty Body Control Module (BCM) is often the culprit behind a host of seemingly unrelated issues, from malfunctioning power accessories to security system errors. This replacement BCM, part number 15095334, is the definitive solution to restore your vehicle’s electronic systems to factory-perfect operation. We take the guesswork and hassle out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This means no expensive trip to the dealership for programming—it arrives ready for installation.
From the Diagnostic Bay
We had a 2002 Sierra in the shop that was driving the owner crazy. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the security light would flash randomly, sometimes preventing the truck from starting. The owner had already replaced the battery and checked all the fuses. After connecting our scanner, we saw multiple communication codes pointing to the BCM. Instead of a complex wiring issue, the fix was a simple swap with a VIN-programmed module like this one. In under an hour, all the bizarre electrical issues were gone, and the truck was reliable again. A single module was the key to solving a dozen different problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ The radio or climate control system functioning intermittently.
- ✔ Diagnostic trouble codes (DTCs) related to U-codes or loss of communication.

Post-Installation Procedures
While our VIN programming handles the majority of the setup, some vehicles may require additional steps after installation to ensure all systems are properly synced. Please be aware of the following potential requirements:
- 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 diagnostic tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration 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
How does the VIN programming service work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to flash the module with the correct software and settings for your exact vehicle before we ship it. This makes installation much simpler.
Is this part truly plug-and-play?
For most vehicles, yes. Our VIN programming covers the essential setup. However, as noted, some models may require a simple relearn procedure for the airbag or brake pedal position sensor, which may require a capable scan tool.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module.
Will this 2002 Avalanche Body Control Module fit other vehicles?
Yes, this BCM is compatible with a wide range of GM trucks and vans from 2002-2005, including the Silverado, Sierra, Tahoe, Yukon, Astro, and Safari. Please check the fitment list and cross-reference your original part number to confirm.
What tools are required for installation?
Installation typically requires basic hand tools like a socket set and screwdrivers to access the module (usually located under the steering column or in the center dash). A professional scan tool may be needed for any post-installation procedures.
