Expert Insight from Our Technicians
“Before you replace your BCM, take a moment to check the main ground connections, especially the one under the driver’s side door sill plate. Corrosion or a loose connection here is a common culprit for BCM-like symptoms on these GM platforms. A simple cleaning can sometimes solve the problem. If the grounds are clean and tight and the issues persist, then replacing the BCM is the next logical step. Installing our Programmed 25844480 Body Control Module on a vehicle with a solid ground connection ensures a lasting repair and prevents damage to the new unit.”
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the central computer for your vehicle’s non-engine related electronic systems. It manages and monitors functions like your power windows, door locks, security system, interior and exterior lighting, wipers, and the HVAC climate control system.
Is this module truly ‘plug-and-play’?
Yes. We pre-program the module using the VIN you provide during checkout. This ensures it communicates perfectly with your vehicle’s other computers right out of the box, with no need for a trip to the dealer for additional programming.
What if my airbag light is on after installation?
In some cases, particularly if DTC B1001 was present, the new BCM needs to be synced with the airbag system’s computer (SDM). This is a simple ‘Setup SDM Primary Key in BCM’ procedure that can be performed with a professional-grade scan tool. This is the only additional step that may be required.

Absolutely. This Programmed 25844480 Body Control Module is a confirmed fit for the 2013 GMC Sierra 2500 and a wide range of other GM trucks and SUVs from 2007 to 2013. Please refer to the detailed fitment list on this page to confirm compatibility with your specific vehicle.
