Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2002 GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, or a security system that won’t cooperate are often signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a wide range of confusing and unpredictable problems. This replacement BCM, part number 15063577, is the definitive solution to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay
We had a customer with a 2002 Yukon XL whose dashboard was a light show of random warnings, the radio would turn on and off by itself, and the power door locks had a mind of their own. He was convinced the vehicle was possessed and was dreading a massive diagnostic bill at the dealership. We identified the BCM as the culprit. By providing him with a pre-programmed module, he was able to swap the part in his own garage over the weekend. The electrical chaos stopped immediately, saving him a tow, a dealership visit, and hundreds of dollars in labor and programming fees.
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 don’t work at all.
- ✔ Malfunctioning instrument cluster gauges or warning lights (like the security light).
- ✔ The anti-theft or security system (Passlock) preventing the engine from starting.
- ✔ HVAC (heating and air conditioning) controls not responding correctly.
- ✔ Intermittent failure of the radio or other interior accessories.
- ✔ Diagnostic trouble codes related to communication errors with other modules.
Why Choose Our Programmed 2002 Tahoe Body Control Module?
The biggest hurdle in replacing a BCM is the need for expensive, dealer-specific programming. We eliminate that step entirely. When you purchase this module, you simply provide us with your vehicle’s 17-digit VIN. Our technicians will then program the BCM with the latest GM software specific to your exact vehicle configuration. This ensures that when the part arrives, it’s ready for installation, saving you time, money, and the hassle of a trip to the service center. This is a direct-fit, plug-and-play solution for the electrical issues plaguing your truck.
Post-Installation Procedures
While this BCM is programmed for your vehicle, some systems may require a simple relearn procedure after installation to ensure full communication between all modules. These are standard procedures and can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function as intended.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during or after checkout, and the module will arrive ready for installation.
Where is the BCM located on my 2002 Tahoe or Yukon?
The Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
What is a VIN and why do you need it?
The VIN is your 17-digit Vehicle Identification Number. We use it to load the precise software and settings from GM for your truck’s specific features and options, ensuring perfect compatibility.
Is this part truly plug-and-play?
For the most part, yes. It is programmed to work with your vehicle’s main functions upon installation. However, as noted above, some simple ‘relearn’ procedures for systems like the airbags or brake sensor may be required in certain cases.
What if my airbag light comes on after I install it?
This indicates the new BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
