Stop Chasing Electrical Gremlins in Your GM Truck or Van

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, the security system, interior and exterior lights, wipers, and the HVAC system. When it fails, these systems can become erratic or stop working altogether.
Why is VIN programming so important?
The BCM needs to communicate with other modules in your vehicle, like the Engine Control Module and the Airbag System. VIN programming loads your vehicle’s specific software and security information onto the BCM, allowing it to sync perfectly with your truck or van. Without it, the module simply will not work correctly.
Is this installation difficult?
No, the physical installation is typically very simple and takes just a few minutes. The BCM is usually located under the driver’s side dashboard near the steering column. Simply disconnect the battery, unclip the electrical connectors, swap the module, and reconnect everything. No special tools are required for the swap itself.
What if the airbag light is on after I install it?
In some cases, the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified mechanic.
Will this fit vehicles other than the Express Van?
Yes, this BCM is compatible with a wide range of 2002-2007 GM trucks and SUVs, including the Chevrolet Silverado, Tahoe, Suburban, Avalanche, GMC Sierra, Yukon, and Cadillac Escalade. Please verify the part number and check the detailed fitment list to ensure it’s the correct module for your specific vehicle.
