Installation and Post-Install Considerations
Physically installing the BCM is straightforward. It’s typically located under the driver’s side dashboard, near the steering column, and can be swapped in under 10 minutes with basic tools. However, please be aware of potential post-installation procedures:
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function. This re-establishes communication between the new BCM and the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and stability control operation.

Frequently Asked Questions
What exactly does the Body Control Module do on my Yukon?
The BCM is a computer that controls and monitors most of the non-engine related electronic functions in your vehicle. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the climate control system.
