Restore Full Electrical Function to Your GM Truck or SUV
Are you battling a cascade of frustrating electrical problems in your Cadillac Escalade, Chevy Silverado, or GMC Sierra? From flickering lights and unresponsive power windows to a malfunctioning HVAC system and persistent warning lights, a failing Body Control Module (BCM) can turn your reliable vehicle into a source of daily headaches. The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can trigger a wide range of seemingly unrelated issues. This genuine quality GM Body Control Module, interchangeable with part number 25790509, is the definitive solution to restore order and functionality.
From the Diagnostic Bay
We had a 2009 Silverado 2500 in the shop that was driving the owner crazy. The radio would cut out randomly, the dome lights wouldn’t work, and the airbag light was on with a B1001 code. He had already replaced the battery and checked fuses with no luck. After plugging in our scanner, we confirmed communication with the BCM was intermittent. A quick inspection under the dash revealed no obvious wiring damage. We installed one of our VIN-programmed BCMs, and nearly all the issues vanished instantly. The final step was performing the ‘Setup SDM Primary Key’ procedure to sync the new BCM with the airbag system, which cleared the final code. It’s a powerful reminder that a single module can be the root of many electrical gremlins.

This isn’t just a replacement part; it’s a complete restoration of your vehicle’s electronic nervous system. Specifically designed for models like the 2007-2011 Escalade ESV BCM, it also fits a huge range of popular GM vehicles including the Tahoe, Suburban, Yukon, Sierra, and Silverado.

Post-Installation Procedures
While the module is designed for plug-and-play installation, some vehicles may require simple relearn procedures. If the airbag warning light appears after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” function. This syncs the new BCM with the airbag system. In some cases, a Brake Pedal Position Relearn may also be necessary to ensure proper brake light and stability control function. Always consult a service manual or a qualified technician if you are unsure about these steps.
Frequently Asked Questions
Do I need to have this BCM programmed by a dealer?

What does the airbag light (DTC B1001) mean after installation?
This indicates that the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A professional scan tool with BCM functions is required to perform the ‘Setup SDM Primary Key’ procedure to sync the systems and turn off the light.
