Installation is straightforward for most DIYers. The BCM is typically located under the driver’s side dashboard, near the steering column. Always disconnect the vehicle’s battery before swapping the module. While our programming resolves most issues, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool if the airbag light remains on after installation. This syncs the new BCM with the airbag system.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related functions, such as the power windows, locks, lights, security system, HVAC, and wipers. It’s the command center for passenger comfort and convenience electronics.
Is this BCM really plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This ensures it works with your specific features and security system right out of the box, eliminating the need for a trip to the dealership for programming.
What if my airbag light is still on after installation?
In some cases, the new BCM needs to be electronically introduced to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by a technician with an advanced diagnostic scan tool.
Where is the BCM located on my 2004 Silverado?
On most 2002-2007 GM trucks and SUVs like the Silverado, Sierra, and Tahoe, the BCM is located under the driver’s side of the dashboard, usually to the left of the steering column.
Do I need to send my old BCM back?
No. This part has no core charge. You can keep your old module without any additional fees or the need to return it.
Will this module fit my 2006 GMC Yukon Denali?
Yes, this BCM is compatible with the 2003-2006 GMC Yukon Denali, as well as a wide range of other GM trucks and SUVs from that era. Please check the full fitment list on the product page to confirm for your specific vehicle.
