Restore Your Vehicle’s Electrical Functions with a Reliable BCM
Are you chasing electrical gremlins in your GM vehicle? Flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or a car that refuses to start intermittently are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
This is a direct-fit replacement Body Control Module, a solution designed to restore full functionality without the exorbitant costs and scheduling headaches of a dealership visit. The biggest hurdle in replacing a BCM has always been the programming. We eliminate that problem entirely. Simply provide your vehicle’s VIN during checkout, and our technicians will flash this module with the latest, most stable GM software specific to your car, truck, or van. This means it arrives at your door ready for a much simpler installation process.
From the Diagnostic Bay
A customer brought in their 2009 Chevy Traverse last month with a truly baffling set of symptoms. The radio would turn on by itself, the dome lights wouldn’t turn off, and the key fob worked only half the time. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw multiple communication loss codes with various modules—all pointing back to the BCM. These modules are the hub for so many circuits, and when they start to fail internally, they create chaotic, seemingly unrelated problems. We installed a pre-programmed BCM just like this one, and within an hour, every single issue was resolved. This is a fix I’ve performed hundreds of times on vehicles from the Impala to the Express Van.
Is Your GM Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, it’s highly likely your Body Control Module is the culprit. This GM Programmed Body Control Module is the definitive solution.
- ✔ Erratic or non-functional power windows, locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system or anti-theft light flashing, preventing the engine from starting.
- ✔ Key fob not responding or working intermittently.
- ✔ Dashboard warning lights (like the airbag light) appearing for no reason.
- ✔ The horn sounding randomly or not working when pressed.
- ✔ Wipers behaving unpredictably.
A Straightforward Guide to BCM Installation
With our pre-programmed module, the most complex part of the job is already done. Follow these general steps for a successful installation. Note: The BCM location varies by model (e.g., under the dash, behind the glove box), so consult a repair manual for your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the BCM: Find the old BCM. It’s typically a black plastic box with several large multi-pin connectors.
- Disconnect and Remove: Carefully unplug all wiring harnesses. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old module and remove it.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all wiring harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect Battery: Re-attach the negative battery terminal.
- Post-Installation Procedures: Turn the key to the ‘ON’ position. You will likely need a professional-grade scan tool to perform two critical relearn procedures: the ‘Setup SDM Primary Key in BCM’ to clear the airbag light and, on some models, a ‘Brake Pedal Position Sensor Calibration’. These steps are essential for safety and full functionality.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before shipment. You just need to provide your vehicle’s 17-digit VIN when you order. This ensures the GM Programmed Body Control Module works correctly with your vehicle’s specific options.
Is this a simple plug-and-play part?
It is nearly plug-and-play. After physical installation, you may need a diagnostic tool to perform a security relearn, reset the airbag system key, and calibrate the brake pedal sensor. These are standard procedures for BCM replacement.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. A failing BCM is a very common cause of security system faults and no-start conditions related to the anti-theft system.
Where is the BCM located on my 2008 Impala?
On the 2006-2013 Impala, the Body Control Module is typically located on the driver’s side, up under the dashboard to the left of the steering column.
What happens if I don’t provide my VIN?
We cannot ship the module without your VIN. The programming is essential for the part to function in your vehicle. We will contact you after your purchase to get the VIN if it was not provided.
Are any other part numbers compatible?
Yes, this module replaces a long list of original GM part numbers, including 15837419, 20935349, and 25910474, among others. Please check the full list to confirm compatibility.
