Restore Full Electronic Functionality to Your GM Vehicle
Are you battling a storm of strange electrical problems in your Chevrolet, GMC, Cadillac, or Buick? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, controlling everything from your power windows and locks to your interior lights and security system. When it fails, it can cause a cascade of confusing and frustrating issues that can be difficult to diagnose.
We recently had a 2011 Chevy Impala in the shop with a list of bizarre symptoms. The radio would randomly shut off, the driver’s side power window worked intermittently, and the security light would stay on, preventing the car from starting. The owner had already replaced the battery and checked fuses with no luck. A quick scan revealed multiple communication errors pointing to the BCM. We installed one of our pre-programmed modules, and within 30 minutes, every single issue was resolved. It’s a common failure, but thankfully, it’s a straightforward fix with the right part.
Is Your Vehicle Experiencing These BCM Failure Symptoms?
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ Vehicle’s security system acting up, causing no-start conditions.
- ✔ Windshield wipers operating randomly or not at all.
- ✔ Instrument cluster warning lights (like Airbag, ABS, or Traction Control) illuminated for no reason.
- ✔ Radio or climate control systems malfunctioning.
- ✔ Key fob not responding.
The Plug-and-Play Solution: A Pre-Programmed GM Body Control Module
Don’t let a faulty BCM keep you off the road or force you into an expensive dealership visit. This replacement GM Body Control Module is the reliable, cost-effective solution you need. We take the hassle out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures it arrives ready for installation, loaded with the latest software updates from GM for optimal performance and compatibility. This process eliminates the need for costly programming tools or a trip to the dealer.
This module is a direct replacement for a wide range of part numbers, including: 10382479, 15828601, 20815898, 22860591, 25892622, and many more. Please see the extensive fitment list to confirm compatibility with your vehicle.
Installation and Required Procedures
Physically swapping the BCM is typically a simple process, often located under the dash or behind a kick panel. Once installed, your vehicle’s primary functions should be restored. However, for safety and system integration, some vehicles may require additional steps:
- Airbag System Sync: If the 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 relearn 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 vehicle-specific instructions.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
You can enter your VIN in the designated field during the checkout process. If you miss it, simply reply to your order confirmation email with your VIN, and we’ll take care of the rest.
Is this part truly plug-and-play?
Yes, it is programmed to your VIN for a plug-and-play installation of all primary functions. However, as noted, some vehicles may require a simple relearn procedure for secondary systems like the airbag (SRS) or brake pedal position sensor to clear warning lights.
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your old module.
What tools are needed for the additional procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional diagnostic scan tool. Most DIY code readers cannot perform these functions.
Will this fix my specific electrical problem?
This module will correct any issues caused by an internal failure of the BCM itself. It’s crucial to ensure your vehicle has been properly diagnosed, as this part will not fix problems related to wiring, sensors, or other components.
