Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing bizarre electrical problems in your Buick Enclave, GMC Acadia, or another compatible GM vehicle? Issues like flickering lights, malfunctioning power windows and locks, a faulty security system, or even a no-start condition often point to a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated symptoms. This replacement Body Control Module, part number 25826125, is the definitive solution to restore your vehicle’s proper operation.
From the Diagnostic Bay
We had a 2011 GMC Acadia come in with a complaint that was a real head-scratcher. The customer said the interior lights would stay on, the radio would randomly shut off, and sometimes the liftgate wouldn’t open. They had already replaced the battery and checked all the fuses. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a complex and expensive wiring chase, we installed a VIN-programmed BCM. The moment it was connected and the necessary relearn procedures were done, all the phantom electrical issues vanished. It’s a perfect example of how a single failing module can make a perfectly good vehicle seem haunted.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your BCM needs replacement:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, or the key fob not working correctly.
- ✔ The instrument cluster displaying incorrect information or warning lights.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ The vehicle failing to start, even with a good battery and starter.
A Simple, Programmed Solution for Your 2008-2012 Enclave Body Control Module
Don’t let a faulty computer keep your vehicle off the road. We make the repair process straightforward. This isn’t just a part in a box; it’s a complete, ready-to-install solution. We flash the module with the latest GM software updates and program it specifically to your vehicle’s VIN before it ships. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Simply provide your VIN at checkout, and we’ll handle the rest.
Post-Installation Requirements
While this module is programmed for your vehicle, some models may require simple post-installation procedures to ensure all systems communicate correctly. This is standard for BCM replacement. Common procedures include:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure proper brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions.

Frequently Asked Questions
How does the VIN programming work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. We use this number to load the correct software and vehicle-specific configuration into the BCM before we ship it. This ensures it communicates correctly with the other modules in your car.
Is this a plug-and-play part?
For many vehicles, yes. Because it comes pre-programmed, it eliminates the most difficult step. However, as noted, some vehicles may require additional relearn procedures for systems like the airbags or brake sensor, which can be completed by a mechanic with a capable diagnostic tool.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module.
Will this fix my specific electrical problem?
This part is designed to fix issues caused by a faulty BCM. The symptoms listed are common indicators, but proper vehicle diagnosis is always recommended to confirm the BCM is the source of the problem before ordering.
What if I install it and the airbag light comes on?
This is a known possibility. It means the new BCM needs to be synchronized with the airbag system’s Supplemental Inflatable Restraint (SIR) module. A qualified technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
