Is Your 2002 GM Truck or SUV Experiencing Strange Electrical Problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, a security light that won’t turn off, or even a no-start condition, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. Don’t let electrical gremlins keep your truck off the road. This direct-fit BCM is the reliable, straightforward solution you need.
The Simple, Reliable Solution for Your Vehicle
This isn’t just a replacement part; it’s a complete solution. We take the guesswork and hassle out of the repair by pre-programming this module to your vehicle’s specific VIN before we ship it. This means it arrives ready for installation, loaded with the latest software updates from GM. This process ensures compatibility and helps restore your vehicle’s functions to factory specifications without requiring a trip to the dealership for expensive programming.
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 working.
- ✔️ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔️ Inaccurate or non-functional instrument panel gauges.
- ✔️ The radio or climate control system behaves unpredictably.
- ✔️ Unexplained battery drain when the vehicle is off.
- ✔️ Communication errors with other vehicle modules (DTC U-codes).

Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require additional steps after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installing the new BCM, a procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure your brake lights and traction control system function correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s electronic accessories. It controls functions like power windows, locks, interior and exterior lighting, the security system, wipers, and more.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you to request your vehicle’s 17-digit VIN. We cannot ship your module until we have this information to perform the necessary programming.
Is this part difficult to install?
The physical installation is typically straightforward. On most 2002 GM trucks like the Yukon or Silverado, the BCM is located under the steering column. It involves disconnecting the battery and swapping the module. However, as noted, some vehicles may require a final sync procedure with a scan tool.
Will this fix my ‘Service 4WD’ light?
While a faulty BCM can cause a variety of issues, a ‘Service 4WD’ message is more commonly related to the Transfer Case Control Module (TCCM) or the encoder motor. It’s important to properly diagnose the issue before ordering parts.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
