Restore Full Electrical Function to Your GM Truck or SUV
Are you battling strange and frustrating electrical issues in your vehicle? Flickering lights, malfunctioning power windows and locks, or a security system that has a mind of its own are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of problems. This replacement BCM is the definitive solution to get your truck’s features working reliably again.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We pre-program the module to your vehicle’s specific VIN before shipping, loading it with the latest GM software updates. This critical step ensures compatibility and saves you from a costly and time-consuming trip to the dealership for programming. Simply provide your VIN after purchase, and we’ll handle the rest.
Symptoms of a Failing 2002 Sierra Denali BCM
- ✔ Erratic or non-functional interior and exterior lights.

Installation and Required Procedures
While this module is programmed for a straightforward installation, some vehicles may require additional relearn procedures after the new BCM is connected. These are standard steps that sync the new module with other systems in your vehicle.
- 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 is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be required to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories such as power windows, locks, lights, wipers, the security system, and more. It’s the brain for your vehicle’s comfort and convenience features.
Is this BCM truly plug-and-play?
Yes, for most vehicles. We program it to your VIN, so it communicates correctly with your truck’s systems right out of the box, eliminating the need for dealer programming. However, as noted, some vehicles may require a simple relearn procedure for the airbag or brake systems.
Where is the BCM located on my 2002 Sierra Denali?
On the 2002 GMC Sierra Denali and similar full-size trucks and SUVs like the Silverado, Tahoe, and Yukon, the BCM is typically located under the driver’s side of the dashboard, near the steering column.
What information do you need from me to program the module?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). This allows us to flash the module with the exact software and configuration for your truck.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
