An improperly programmed module can cause even more issues than the one you’re replacing.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your truck’s body electronics. It controls non-engine related functions like your power windows, door locks, interior and exterior lighting, security system, climate control fans, and wipers. When it fails, these systems can behave erratically or stop working altogether.
Is this module difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The BCM is usually located under the driver’s side dashboard, near the steering column. The process involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors. Since our module is pre-programmed, no special computer tools are needed for the basic installation.
What if my airbag light is on after installation?
In some cases, particularly if you have an airbag-related code like B1001, the new BCM may need to be synced with the airbag system’s computer (SDM). This is a security feature and requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple step for any qualified technician.
Will this fit vehicles other than a 2013 GMC Sierra 3500?
Yes, this BCM is compatible with a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Tahoe, Suburban, Yukon, and Escalade. However, it is crucial to confirm the part number (interchangeable with 25844480, 25835966, and others) matches your original unit to guarantee compatibility with your specific vehicle. This listing is specifically for a 2013 GMC Sierra 3500 Body Control Module and will be programmed accordingly.
Do I need to send my old BCM back?
No. We do not require a core return for this part. You can dispose of or keep your old module, making the replacement process faster and more convenient for you.
