Restore Full Control and End Electrical Gremlins
Are you battling frustrating and unpredictable electrical issues in your vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or strange warning lights on your dash are all common signs of a failing Body Control Module (BCM). This isn’t just an annoyance; it’s a critical failure in your vehicle’s central nervous system. This pre-programmed BCM is the definitive, reliable solution to restore your vehicle’s electronic functions and get you back on the road with confidence.
Common Symptoms & Your Solution

- Interior or exterior lights not working correctly (staying on, not turning on, or flickering)
- Power windows, door locks, or mirrors operating erratically or not at all
- Vehicle’s anti-theft or security system preventing the car from starting
- Inaccurate readings on the instrument cluster gauges
- Communication error codes (U-codes) when scanned with a diagnostic tool

An Expert’s Insight on BCM Replacement
As a technician with over 20 years on the floor, I can tell you that chasing electrical gremlins is one of the most time-consuming jobs. A customer might come in with a dead battery, and you find the interior lights never turned off. Another might have a car that won’t start intermittently due to a security fault. The common link is often the BCM. The real magic of a service like this is the pre-programming. It turns a potentially complex, multi-day repair requiring dealer-level tools into a job that a confident DIYer or any independent shop can complete efficiently. It’s the smartest way to solve a very complex problem.
Post-Installation Information
While this module is designed for a simple installation, some vehicles may require one or two final sync procedures to ensure all systems communicate correctly. These are standard procedures that can be performed by any qualified technician with a professional-grade scan tool:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary for proper brake light and traction control operation.
Always consult a factory service manual or a qualified professional for vehicle-specific instructions.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of non-engine-related functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster. When it fails, these systems can behave erratically.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We will provide clear instructions on how to do this. We cannot ship your part until we have programmed it with your specific VIN.
Will I need to do any programming myself?
No. The primary programming is done by us before the BCM is shipped. It will arrive ready to be installed. However, as noted above, some vehicles may require minor relearn or sync procedures with a scan tool after installation for systems like the airbags or brakes.
How do I know for sure that my BCM is the problem?
While the symptoms listed are strong indicators, a definitive diagnosis from a qualified technician using a professional scan tool is the best way to confirm BCM failure. They can check for specific communication codes and rule out other potential causes like wiring or switch issues.
What if my original part number isn’t 20864767?
This module is a direct replacement for the extensive list of part numbers shown in the fitment data. As long as your original part number is on that list, this module will be a compatible replacement for your vehicle once programmed.
Is this a new or used part?
This is a high-quality, genuine OEM part that has been meticulously inspected and tested to ensure it meets or exceeds original performance standards. We then program it with the latest software for your vehicle.
