Important Installation Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part is fitted. Please be aware of the following potential procedures:
- Airbag System Sync: If your 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 some models, a brake pedal position sensor recalibration 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 guidance. This module is a direct replacement for a wide array of GM part numbers. Please verify your original part number against the list on this page to ensure compatibility.
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 many of its non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and instrument cluster functions.
Is this BCM truly ready to install?
Yes, for most vehicles. We program the module to your specific VIN before shipping, which handles the most critical step. In some cases, minor relearn procedures, like for the brake pedal position sensor, may be required after installation.
How do I find my original BCM part number?
Your original BCM’s part number is printed on a sticker directly on the module itself. You will need to locate the module in your vehicle (common locations are under the dash or behind a kick panel) to read the number.
What happens if the airbag light comes on after installation?
This indicates that the new BCM needs to be electronically synced with your vehicle’s airbag system (SDM). This is a security feature and requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to send my old BCM back?
No. This part is sold without a core charge, so you can keep your original module.
