Is Your Truck Plagued by Electrical Gremlins?

Frequently Asked Questions
Will this BCM need to be programmed by a dealer?
No. The main benefit of our service is that we pre-program the module to your vehicle’s VIN before shipping. This makes the installation a simple plug-and-play process, saving you a trip to the dealership and additional programming fees.
Where is the Body Control Module located on my truck?
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, near the steering column. Installation is straightforward and typically takes less than 15 minutes.
What if my airbag light is on after I install the new BCM?
In some cases, the new BCM may need to be synced with the airbag system (SDM). If the airbag light appears after installation, a procedure called “Setup SDM Primary Key in BCM” will need to be performed using a professional-grade scan tool. This is a simple procedure for most automotive shops.
How do I provide my vehicle’s VIN?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy, as this is crucial for correct programming.
