Restore Full Electronic Function to Your GM Vehicle
Are you battling frustrating electrical problems in your Chevrolet, GMC, Cadillac, or other GM vehicle? Issues like erratic power windows and locks, a malfunctioning security system, intermittent warning lights, or accessories that have a mind of their own are often traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics. When it fails, it can cause a cascade of confusing and unpredictable symptoms. This replacement GM Body Control Module is the definitive solution to restore your vehicle’s proper operation and get you back on the road with confidence.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The anti-theft or security system preventing the car from starting.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate or erratic gauge readings on the instrument cluster.
- ✔ Remote keyless entry failing to lock or unlock the doors.
- ✔ Communication error codes with other vehicle modules (U-codes).
Plug & Play Solution: The Advantage of VIN Programming
Replacing a BCM isn’t just a matter of swapping parts. A new module must be programmed with your vehicle’s specific information and options to function correctly. This typically requires a trip to the dealership and expensive diagnostic tool time. We eliminate that hassle. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program this GM Body Control Module with the latest GM software and your vehicle’s exact configuration. When you receive the part, it’s ready for installation, saving you time and money.
Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require a simple relearn procedure after installation. This is common in modern vehicles where modules need to handshake with each other. For this BCM, you may need to perform:
- 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 needed to ensure correct brake light operation and to satisfy the traction control system.
Please consult a factory service manual or a qualified technician for vehicle-specific instructions.
