Solving Problems with a Programmed 2003-2007 Sierra 1500 BCM
Replacing a faulty module is the definitive solution to these persistent issues. Our 2003-2007 Sierra 1500 BCM is built to strict OEM standards for reliability and longevity. Because we program it with the latest GM software updates using your VIN, it ensures seamless communication with your vehicle’s other electronic modules, like the SDM (airbag module), right out of the box. This resolves common communication-related diagnostic trouble codes (DTCs) and restores dependable operation to all related systems.
Installation & Post-Install Notes:
Installation is straightforward and usually takes less than 15 minutes. After installing the new BCM, reconnect the battery. In some cases, particularly if the airbag light was on, a ‘Setup SDM Primary Key in BCM’ procedure may be required using a professional scan tool to sync the modules.

Frequently Asked Questions
What does this Body Control Module do?
The BCM is a computer that controls many of your vehicle’s electronic accessories, such as power windows, door locks, interior/exterior lights, wipers, and the HVAC system. A failing BCM is a common cause of these systems malfunctioning.
Is this part ready to install out of the box?
Yes! We pre-program this BCM to your vehicle’s VIN before shipping. This ensures it works with your specific options and security system without requiring a trip to the dealer for additional programming.
Where is the BCM located on my 2003-2007 Sierra 1500?
On most 2003-2007 GM trucks and SUVs like the Sierra, Silverado, and Tahoe, the BCM is located under the driver’s side of the dashboard, typically to the left of the steering column.
What if my airbag light stays on after installation?
If the airbag light remains on, it means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Do I need to return my old BCM?
No, there is no core charge for this part. You can keep your original module without any extra fees or hassle.
Will this fit vehicles other than a Sierra 1500?
Yes, this BCM fits a wide range of 2002-2007 GM vehicles, including the Chevrolet Silverado, Tahoe, Suburban, Avalanche, and Express Van, as well as the GMC Yukon, Savana Van, Cadillac Escalade, and Hummer H2. Please verify the part number for your specific model.
