A Master Tech’s Tip: Check Your Grounds First
“Before you replace any module, especially a BCM on these GM trucks, do yourself a favor and check the main ground connections. A common trouble spot is the ground pack located on the frame under the driver’s side door. A loose or corroded ground can cause the exact same bizarre electrical symptoms as a bad BCM. A quick check with a wrench can sometimes save you the cost of a part. If the grounds are tight and clean and the problems persist, this programmed 25844480 BCM is your next step for a lasting repair.”
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central hub for your vehicle’s body electronics. It controls non-engine-related functions like power windows, door locks, the security system, interior and exterior lighting, wipers, and the HVAC system.
Is this part really plug-and-play?
Yes. We use your vehicle’s VIN to program the module with the latest GM software before it ships. This ensures it communicates correctly with your specific vehicle, making installation as simple as swapping the part. No trip to the dealer is necessary for programming.
How do I know if my BCM is failing?
Common symptoms include multiple, unrelated electrical issues happening at once, such as lights flickering, locks not working, and HVAC problems. Diagnostic trouble codes related to body functions, especially a persistent airbag code like B1001, are also strong indicators.
Where is the BCM located on my truck or SUV?
On most compatible GM trucks and SUVs from 2007-2013, the BCM is located under the driver’s side dashboard, near the steering column. Installation typically takes only a few minutes with basic tools.
What if the airbag light stays on after installation?
In some cases, particularly if DTC B1001 was present, a special procedure called “Setup SDM Primary Key in BCM” is required. This is not programming but a security sync that must be done with an advanced diagnostic scan tool. Most professional repair shops can perform this function quickly.
Do I need to send my old part back?
No. We do not require a core return for this module. You can keep or dispose of your old part, making the process simple and hassle-free.
