Restore Your Vehicle’s Electrical System
Are you battling frustrating electrical problems in your GM vehicle? Intermittent power windows, flickering lights, a malfunctioning security system, or dashboard warning lights that won’t turn off are common signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of confusing and unpredictable issues. This replacement module is the definitive solution to restore full functionality and peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
- ✔ Malfunctioning security system or keyless entry.
- ✔ Inaccurate or dead gauges on the instrument cluster.
- ✔ Warning lights (like the airbag or ABS light) appearing for no reason.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.

Post-Installation Requirements
While this module is programmed for a straightforward installation, some vehicles may require additional steps to ensure all systems communicate correctly. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated 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 certain models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages many of your vehicle’s non-engine related functions. This includes power windows, locks, seats, interior and exterior lighting, the security system, and communication between various electronic components.
How does the VIN programming work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the correct GM software and vehicle-specific settings onto the BCM before shipping it. This makes the installation process much simpler.
Is this part difficult to install?
The physical replacement is typically straightforward, involving unplugging the old module and plugging in the new one. The BCM is often located under the dashboard. However, as noted, some vehicles may require additional electronic ‘relearn’ or ‘sync’ procedures with a professional scan tool to finalize the installation.
Will this fix my specific problem?
This module will correct issues directly caused by a faulty BCM. While the symptoms listed are very common, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the source of the problem before ordering.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-end scan tool to resolve this.
