Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a security system that acts on its own, or strange warning messages on your dash, the culprit is often a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can cause a wide range of frustrating and unpredictable issues. Don’t waste time and money chasing down individual component failures. This direct-fit BCM is the reliable solution to restore your vehicle’s proper function.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, mirrors, or door locks not working correctly.
- ✔ Horn sounding unexpectedly or not working at all.
- ✔ Vehicle security system faults or false alarms.
- ✔ Inoperative remote keyless entry (RKE).
- ✔ Communication errors with diagnostic scan tools.
- ✔ Intermittent ‘Service 4WD’ or other warning lights.

Important Post-Installation Information
While this module is programmed for your vehicle, certain security and safety systems may require a ‘handshake’ procedure after installation. This is a normal part of the process for many modern vehicles.
- Airbag System Sync: If your 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 your vehicle’s existing 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 function.
Always consult a factory service manual or a qualified technician if you are unsure about any step of the installation or post-installation process.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, interior/exterior lighting, security system, wipers, and the horn.
Is this part difficult to install?
The physical installation is typically straightforward. On most 2002 GM trucks like the Sierra and Silverado, the BCM is located under the steering column and is accessible by removing a lower dash panel. The main challenge can be the post-installation procedures, which may require a professional-grade scan tool.
Do I need to send my old part back?
No, there is no core charge for this module. You can keep your original part.
What do I need to do after I purchase?
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it. This ensures the module is correctly configured for your vehicle’s specific options.
Will this fit my 2002 Chevy Silverado?
Yes, this BCM fits a wide range of 2002 GM trucks and SUVs, including the Silverado 1500, 2500, and 3500, as long as the part number on your original module matches one of the listed compatible numbers (15063578, 15081796, etc.).
