Is Your 2002 GM Truck or SUV Experiencing Bizarre Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security system that acts up, or intermittent starting issues, the root cause is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a host of frustrating and unpredictable problems. This replacement Body Control Module is the definitive solution for your 2002 GMC Yukon, Sierra, Silverado, Tahoe, and a wide range of other GM vehicles, restoring full functionality and reliability.
From the Diagnostic Bay
We had a 2002 Silverado in the shop that was driving the owner crazy. The dome lights would stay on, the radio would randomly shut off, and the ‘Security’ light would flash, sometimes preventing the truck from starting. After checking the usual suspects like grounds and fuses, we pinpointed the BCM. Instead of sending the owner to a dealership for a costly replacement and programming, we installed one of our VIN-programmed modules. The installation was straightforward, and all the strange electrical gremlins vanished immediately. It’s a common failure, and having a pre-programmed unit ready to install is the most efficient fix.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The vehicle’s security system engaging randomly, causing a no-start condition.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or non-functional instrument panel gauges.
- ✔ Communication errors with other vehicle modules, triggering various warning lights.

Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicles may require additional relearn procedures after the BCM is installed. These are standard procedures that can be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might 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
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, security system, wipers, and interior accessories.
Is this BCM truly plug-and-play?
This BCM is pre-programmed to your VIN, making it as close to plug-and-play as possible. It eliminates the need for dealership programming. However, as noted, some vehicles may require simple relearn procedures for systems like the airbags or brake sensor after installation.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
Where is the BCM located on my 2002 GM truck?
On most 2002 GM full-size trucks and SUVs like the Yukon, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, near the steering column. On vans like the Astro and Safari, it is typically behind the center dash.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
