Restore Full Electrical Function to Your GM Truck
Are you battling strange and frustrating electrical problems in your Chevrolet Silverado, GMC Sierra, or another GM truck? Flickering lights, unresponsive power windows, a malfunctioning security system, or an illuminated airbag light are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can cause a cascade of issues that are difficult to diagnose. This VIN-programmed BCM, equivalent to GM part number 25844480 and interchangeable with 15940214, is the definitive solution to restore your vehicle’s performance and reliability.
Is Your Truck Showing Signs of BCM Failure?
A faulty BCM can manifest in numerous ways, often making you think multiple components have failed at once. Look out for these common symptoms:
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ HVAC and climate control systems behaving erratically.
- ✔ The security system preventing the truck from starting or causing random alarm triggers.
- ✔ An airbag warning light on the dash, often with a DTC B1001 code.
- ✔ Unexplained battery drain while the vehicle is off.

Forget expensive dealership visits and programming fees. We take the hassle out of the repair by pre-programming this module to your truck’s specific Vehicle Identification Number (VIN). This ensures that it integrates seamlessly with your vehicle’s existing systems right out of the box. This is a direct-fit replacement for a wide range of GM trucks and SUVs from 2007-2013, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade. It is a direct replacement for multiple part numbers, including 15940214, 25835966, 20939137, and 22860591.
Installation is straightforward for any DIYer with basic tools. The BCM is typically located under the driver’s side of the dashboard, near the steering column. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. In most cases, that’s all it takes to get back on the road. For persistent airbag lights, a post-install ‘Setup SDM Primary Key’ procedure may be required using a capable scan tool.
