Restore Your Vehicle’s Electrical System
Are you battling bizarre and frustrating electrical problems in your GM vehicle? Flickering lights, malfunctioning power windows, a security system that acts on its own, or an engine that refuses to start can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can create a cascade of confusing issues. This replacement BCM is your direct-fit, reliable solution, pre-programmed to your vehicle’s specific VIN to ensure a seamless installation and restore proper function.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Security system faults or alarm sounding unexpectedly.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ False warning lights on the dashboard, such as the airbag or brake light.
- ✔ Radio or infotainment system malfunctions.

Important Post-Installation Steps
While this module is designed 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 procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls a wide variety of electronic accessories, such as power windows, interior/exterior lighting, security systems, power locks, and wipers.
Do I need to have this BCM programmed by a dealer?
No. We handle the programming for you before we ship the part. Just provide your vehicle’s VIN at checkout, and it will arrive ready to be installed, flashed with the latest GM software for your specific vehicle.
Where can I find my vehicle’s VIN?

What should I do if my airbag light turns on after I install the BCM?
