Are you battling bizarre and frustrating electrical problems in your GM vehicle? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from your interior lights and power windows to the security system. When it starts to fail, it can cause a cascade of seemingly unrelated issues, making diagnosis a nightmare.
This is a direct-fit, plug-and-play solution for a wide range of GM vehicles, including models from Chevrolet, GMC, Cadillac, Buick, Pontiac, and Saturn. We take the guesswork and high cost out of the repair by programming this module to your vehicle’s specific VIN before it ships. This ensures compatibility and proper function of your vehicle’s options, saving you a costly trip to the dealership for programming.
Is Your Vehicle Experiencing These Symptoms?
- ✔ Erratic or non-functional interior/exterior lights (dome, headlights, taillights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Security system faults or the engine refusing to start (anti-theft related).
- ✔ The radio or climate control system not turning on or off correctly.
- ✔ Warning lights on the dash, such as for the airbag or brake system.
- ✔ Communication errors with diagnostic scan tools (U-codes).
The Reliable Solution: A Programmed GM Body Control Module
Don’t let a faulty BCM keep your vehicle off the road. Our replacement GM Body Control Module is the most effective and straightforward way to restore your vehicle’s electronic functions. By providing us with your VIN during checkout, you receive a unit that is loaded with the latest GM software specific to your vehicle’s build. This module is a direct replacement for a wide array of part numbers, including 15276271, 22860591, 25892622, and many more, ensuring broad compatibility.
While the module is designed for a simple installation, please be aware that some vehicles may require a post-installation relearn procedure. For instance, if the airbag light appears, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and traction control operation. These are standard procedures for this type of repair.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your car that controls and monitors a wide range of electronic accessories not related to the engine, such as power windows, locks, lights, wipers, and the security system.
How do I know if my BCM is the problem?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. For example, your radio might not work, and your power windows might be stuck. A professional diagnosis is always recommended, but these symptoms are strong indicators.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the exact software and settings for your specific vehicle’s options (like sunroof, power seats, etc.). This makes the part plug-and-play and avoids a mandatory trip to the dealer for programming.
Is this part difficult to install?
The physical replacement is typically straightforward, often involving removing a few dash panels to access the module. However, some vehicles may require a simple ‘relearn’ procedure with a scan tool for systems like the airbags or brakes after installation, as noted in the description.
Will this fix my ‘Service Airbag’ light?
If the light is caused by a faulty BCM, yes. However, after installing the new BCM, the airbag system (SDM) must be synced with the new module using a professional scan tool. This procedure, called ‘Setup SDM Primary Key in BCM’, will turn off the light.
Is there a core charge?
No, there is no core charge for this part. You can keep your old module.
