Are you battling frustrating electrical gremlins in your 2002 GM truck or SUV? Flickering lights, malfunctioning power windows, a security system that acts up, or strange warning messages on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module, part number 15063577, is the definitive solution to restore full functionality and reliability to your vehicle.
This isn’t just a generic part off the shelf. We program each module specifically to your vehicle’s VIN before it ships. This critical step ensures seamless integration with your truck’s existing systems, loading the latest software updates from GM. This process eliminates the need for an expensive trip to the dealership for programming, saving you time and money and getting you back on the road faster.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security system or alarm randomly activates or prevents the vehicle from starting.
- ✔ Inaccurate or erratic gauge cluster behavior.
- ✔ Warning lights such as the airbag or ABS light illuminating for no reason.
- ✔ Problems with the radio or climate control functions.
- ✔ A persistent battery drain that leaves you with a dead battery.

We had a 2002 Tahoe come in that was driving the owner crazy. The radio would turn on and off by itself, the dome lights would flicker while driving, and occasionally the power locks wouldn’t respond. He had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors all pointing back to the BCM. We installed one of our VIN-programmed modules, and it was like a new truck. All the strange electrical issues vanished instantly. It’s a perfect example of how a single failing module can create a cascade of seemingly unrelated problems.
Installation and Post-Install Information
The BCM is typically located under the steering column for easy access. After installation, while our programming handles the majority of the setup, some vehicles may require additional steps:
- Airbag System Sync: If the airbag warning light is on 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 necessary to ensure correct brake light operation and traction control performance.
Please Note: While many installations are plug-and-play, specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician.

Frequently Asked Questions
What does the Body Control Module do?
The BCM is a computer that controls many of the non-engine related functions in your vehicle, such as power windows, locks, lights, security system, wipers, and more. It’s the brain for your vehicle’s electronic accessories.
Is this BCM difficult to install?
The physical installation is generally straightforward. The BCM is located under the driver’s side dashboard, near the steering column. Basic hand tools are all that’s required for removal and replacement.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will program the BCM with the latest GM software matched to your specific vehicle before shipping.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
