Is Your GM Vehicle Acting Possessed?
Are you dealing with flickering lights, power windows that have a mind of their own, a security light that won’t turn off, or a car that refuses to start? These frustrating and seemingly random electrical issues often point to one culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of confusing problems. Don’t let electrical gremlins keep you off the road. This direct-fit, VIN-programmed BCM is the reliable solution to restore your vehicle’s proper function.
Common Symptoms of a Failing GM Body Control Module
- ✔ Erratic or non-functional interior and exterior lights
- ✔ Power windows, door locks, or mirrors not working correctly
- ✔ Vehicle security system faults or anti-theft light staying on
- ✔ Intermittent no-start or no-crank conditions
- ✔ Horn, wipers, or radio functioning improperly
- ✔ False warnings or error messages on the instrument cluster
- ✔ Rapid battery drain while the vehicle is off
The Simple, Reliable Solution
Replacing a BCM used to mean a mandatory trip to the dealership for expensive parts and programming. We’ve eliminated that hassle. This GM Body Control Module arrives at your door fully programmed to your vehicle’s specific VIN. We load it with the latest software updates from GM, ensuring optimal performance and compatibility. This makes installation a straightforward process for you or your mechanic, getting you back on the road faster and for less money.
Post-Installation Procedures
While this module is designed for a simple installation, some vehicle systems may require a quick relearn procedure to sync with the new BCM. This is standard for 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 the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and other comfort and convenience features.
How does the VIN programming work?
After you place your order, you simply provide us with your vehicle’s 17-digit VIN. We use this number to access the correct software and calibration files from GM and flash them onto the module before we ship it. This ensures it works correctly with the specific options your vehicle was built with.
Is this part difficult to install?
The physical replacement is typically straightforward, involving the removal of a few dash panels to access the module. Since our BCM comes pre-programmed, you eliminate the most complex step. However, due to the potential need for post-installation relearn procedures, we recommend installation by a professional mechanic or an experienced DIYer with access to a high-level diagnostic scan tool.
Will this BCM fit my vehicle?
This module is a direct replacement for a wide range of 2006-2013 GM vehicles, including the Impala, Tahoe, Yukon, Acadia, Express/Savana vans, and more. It replaces numerous part numbers, including 15828601, 25892622, and 22860591. Please verify your part number or use the fitment chart to confirm compatibility.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module.
What if the airbag light comes on after I install it?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
