Restore Your Vehicle’s Electrical Functions
Are you experiencing strange and frustrating electrical issues in your GM vehicle? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away are all common signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing problems. This replacement GM Body Control Module is the reliable, plug-and-play solution to get your car, truck, or SUV back to normal.
Symptoms of a Failing GM BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Vehicle security system faults or anti-theft light illumination.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Parasitic battery drain that kills your battery overnight.
- ✔ Communication errors with other vehicle modules (DTC U-codes).
Why Choose Our GM Body Control Module?
This isn’t just a replacement part; it’s a complete solution. We take the hassle out of the repair by programming the module to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures it communicates correctly with your vehicle’s other systems right out of the box, loaded with the latest GM software updates. This process eliminates the need for expensive programming tools or a trip to the dealership, saving you significant time and money.
Installation and Setup
Physical installation is typically straightforward, as the BCM is often located under the dash. Once installed, the module is ready to operate. However, depending on your specific model and options, a few simple relearn procedures may be necessary:
- 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: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
