Restore Full Electrical Function to Your 2002 GM Truck or SUV
Are you battling frustrating electrical gremlins in your 2002 Yukon, Tahoe, Escalade, or other GM full-size vehicle? Symptoms like flickering lights, malfunctioning power windows and locks, a dead instrument cluster, or a security system that prevents your truck from starting often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent issues. This replacement Body Control Module, part number 15081857, is the direct-fit solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We had a 2002 Chevy Avalanche come in that was driving the owner crazy. The radio would cut out, the dome lights would flash randomly, and sometimes the 4WD service light would pop on for no reason. The owner had already replaced the battery and checked all the main fuses. After hooking up our diagnostic tool, we saw multiple communication error codes all pointing back to the BCM. Instead of a costly trip to the dealer, we installed one of our VIN-programmed modules. The installation was straightforward, and once connected, all the strange electrical issues were gone. The customer was thrilled to have his truck back to normal without the dealership hassle.

Installation & Post-Install Information
The BCM is typically located under the driver’s side of the dashboard, near the steering column. While installation is a plug-and-play process, some vehicles may require additional steps after the new module is connected. Please be aware of the following potential procedures:
- 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 syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control system performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, security system, and interior accessories.
Is this BCM difficult to install?
The physical installation is generally simple, involving unplugging the old module and plugging in the new one. However, as noted, some vehicles may require post-installation relearn procedures with a diagnostic tool for systems like the airbags.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your part until we receive this information to program the module correctly.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be synced with the airbag system. A qualified mechanic with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this part fix my specific problem?
This 2002 Yukon Body Control Module resolves issues directly caused by a failing BCM. While it fixes a wide range of electrical problems, we always recommend a proper diagnosis by a qualified technician to confirm the BCM is the root cause before ordering.
