Installation & Post-Install Notes
Installation is straightforward. Simply disconnect the vehicle’s battery, locate the BCM under the driver’s side dash (near the steering column), and swap the modules.

Always consult a service manual for your specific vehicle if you are unsure.

Frequently Asked Questions
What does the Body Control Module do on my Escalade?
The BCM acts as the brain for your truck’s body electronics. It controls non-engine related functions like power windows, door locks, interior/exterior lighting, the security system, wipers, and the climate control system.
Will I need to take my truck to the dealer after installing this?
No. This Escalade EXT Body Control Module comes pre-programmed to your vehicle’s VIN. This eliminates the need for dealership programming, making it a true plug-and-play installation.
My airbag light is on. Will this fix it?
A failing BCM can cause the airbag light to illuminate. Replacing it often solves the problem. However, if the light stays on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be required using a professional scan tool to sync the new BCM with the airbag system.
Is this part compatible with other GM trucks and SUVs?
Yes, this BCM is compatible with a wide range of 2002-2007 GM vehicles, including the Silverado, Sierra, Tahoe, Yukon, Suburban, Avalanche, and Hummer H2. Please verify the part number or use our fitment tool to ensure it’s correct for your specific vehicle.
