Frequently Asked Questions
What does the Body Control Module do on my Hummer H2?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, the security system, and the HVAC controls.
Do I need to have this BCM programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This makes it a plug-and-play installation, saving you time and money.
Where is the BCM located on a 2003-2007 Hummer H2?
The Body Control Module is typically found on the driver’s side, under the dashboard to the left of the steering column.
What if my airbag light stays on after installing the new BCM?
If the airbag light remains on, it means the new BCM needs to be synchronized with the airbag’s Sensing and Diagnostic Module (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be performed with a professional-grade diagnostic tool.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us.
