Is Your 2002 GM Truck or SUV Experiencing Strange Electrical Problems?
If your power windows have a mind of their own, your interior lights flicker, the security light stays on, or your gauges act erratically, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. Stop chasing electrical gremlins and get the direct-fit solution for your vehicle.
This is a replacement Body Control Module, part number 15081857, for a wide range of 2002 General Motors trucks and SUVs. The best part? We handle the programming for you. Simply provide your vehicle’s 17-digit VIN during checkout, and we will flash the module with the latest GM software updates specific to your truck. This saves you a costly trip to the dealership and eliminates the need for expensive scan tools for initial setup, getting you back on the road faster.
From the Diagnostic Bay
We had a 2002 Tahoe come in that was driving the owner crazy. The battery would die overnight, but the battery and alternator tested perfectly. The radio would turn on and off by itself, and the power locks worked intermittently. The owner had spent hundreds on diagnostics at other shops with no luck. We suspected the BCM, and after installing one of our pre-programmed modules, every single issue was resolved. A failing BCM can mimic a dozen other problems, making it one of the most common yet misdiagnosed failures on these trucks.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows and locks
- ✔ Interior or exterior lights flickering, staying on, or not working at all
- ✔ The security or anti-theft light is illuminated on the dash
- ✔ Inaccurate or dead gauges on the instrument cluster
- ✔ Problems with the radio or climate control functions
- ✔ Unexplained battery drain or no-start conditions
Installation for Your 2002 Yukon Body Control Module
This BCM is located under the driver’s side of the dashboard, near the steering column. While installation is straightforward for a DIY mechanic, some post-installation procedures may be required depending on your vehicle’s specific configuration.
Post-Installation Procedures:
Airbag System Sync: If your airbag warning light is on after installing the new BCM, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and requires a professional-grade diagnostic tool. This is only necessary if the light appears.
Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure the brake lights and traction control system function correctly. This also typically requires a diagnostic tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s specific VIN before shipping. Please provide your 17-digit VIN at checkout to ensure compatibility and proper function.
Where is the BCM located on my 2002 Yukon or Tahoe?
The Body Control Module is located under the driver’s side dashboard, typically attached to a bracket near the steering column.
What if my airbag light turns on after I install it?
This indicates the new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
How do I know if the BCM is really my problem?
While this part corrects the most common BCM-related failures, we always recommend a proper diagnosis by a qualified mechanic. Check for consistent power and good grounds at the module before ordering to confirm the BCM is the point of failure.
