Installation and Compatibility for your 2003-2007 Sierra 3500 BCM
Replacing the BCM is a straightforward job for a DIY mechanic. It is typically located under the driver’s side dashboard, near the steering column. The process involves disconnecting the battery, removing a few trim panels for access, and swapping the electrical connectors from the old module to the new one. The entire process can often be completed in under 30 minutes. As this is a pre-programmed unit, no further steps are usually needed. However, in some cases, post-installation procedures may be required. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. A brake pedal position sensor relearn might also be necessary on certain models. This 2003-2007 Sierra 3500 BCM is the perfect solution for your repair needs.
This BCM is a direct replacement for a wide range of GM vehicles and interchanges with part numbers including: 15116066, 15136225, 15137393, 15198116, 15257043, and 10367690. It fits models like the Chevrolet Silverado, Suburban, Tahoe, GMC Sierra, Yukon, Cadillac Escalade, and Hummer H2 from 2002-2007. Please verify fitment for your specific vehicle.
