Is your vehicle experiencing bizarre electrical problems? You may have a failing Body Control Module.
The Body Control Module, or BCM, is the central command center for your vehicle’s body electronics. It manages everything from your power windows and door locks to your interior and exterior lights, security system, and more. When the BCM starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues, making your vehicle unreliable and difficult to operate.
From the Diagnostic Bay
We had a 2008 Chevy Impala come into the shop with the classic signs of a BCM failure. The customer complained that the radio would turn on and off by itself, the power locks worked intermittently, and the security light would stay on, sometimes preventing the car from starting. After confirming power and grounds to the module were good, we identified the BCM as the culprit. Instead of a costly trip to the dealer for a new module and programming, we installed a pre-programmed unit. The entire process was done in under an hour, resolving all the electrical gremlins and saving the customer significant time and money.
Symptoms of a Failing GM Body Control Module
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system acting up, causing no-start conditions or false alarms.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Wipers behaving erratically or not parking in the correct position.
- ✔ Warning lights on the dashboard, such as the airbag or brake light, illuminating for no reason.
A Simple, Reliable Solution: The Programmed GM BCM
Don’t let a faulty BCM keep you off the road. This replacement Body Control Module is the most efficient solution to restore your vehicle’s electronic functions. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific VIN before it ships. This means it arrives ready for installation, loaded with the latest software updates from GM. This process eliminates the need for expensive dealership programming tools, making it a straightforward swap for a DIY mechanic or local shop.
This module is a direct replacement for a wide range of original equipment part numbers, ensuring compatibility and proper function. It is a reliable and cost-effective alternative to the dealership.
Installation and Post-Install Notes
Installation is typically plug-and-play. However, due to the complexity of modern vehicle systems, some models may require a simple relearn procedure after the new module is installed. Specifically:
- 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 the airbag system.
- Brake Pedal Position Relearn: On some vehicles, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
This part has no core charge! You can keep your old module without any extra fees.

Frequently Asked Questions
What does ‘programmed to my VIN’ mean?
It means we flash the module with your vehicle’s specific factory software and settings using your unique 17-digit Vehicle Identification Number (VIN). This ensures the BCM works correctly with the options and systems your vehicle was built with, saving you a trip to the dealership for programming.
Is this BCM difficult to install?
For most models, the BCM is located under the dash and is a plug-and-play component. Basic hand tools are usually all that’s required. However, some vehicles may require additional relearn procedures after installation, which might necessitate a professional scan tool.
How do I provide my VIN?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. Please double-check your VIN for accuracy to avoid delays.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause of your problem before ordering.
What if the airbag light comes on after I install it?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a repair shop with a professional-grade diagnostic tool.
Do I have to send my old part back?
No. There is no core charge for this part. You can keep or dispose of your original module.
