Frequently Asked Questions
What does a Body Control Module do on a Hummer H2?
The BCM acts as the central computer for your H2’s body electronics. It controls non-engine related functions like power windows, door locks, security system, interior and exterior lighting, wipers, and the HVAC system, ensuring they all work together correctly.
Is this BCM difficult to install?
Installation is typically straightforward for someone with basic mechanical skills. The BCM is located on the driver’s side, accessible from under the dash. Because it comes pre-programmed, the physical swap is all that’s needed, often taking less than 15 minutes. Always disconnect the battery before starting.
Why is VIN programming so important?
VIN programming loads your Hummer’s specific software and configurations onto the module. Without it, the BCM won’t be able to communicate properly with the other computers in your vehicle, leading to incorrect function or complete failure of certain features. Our service saves you a mandatory and costly trip to the dealership.
Will I need to do anything after installing this module?
In some cases, yes. If your airbag light is on, a procedure to sync the airbag system (SDM) may be needed using a professional scan tool. A brake pedal position sensor relearn might also be required on some models. These are standard procedures after a BCM replacement.
What if my airbag light is on after installation?
This is a common security measure. You will need a qualified technician with a high-level scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system and will turn off the warning light.
Does this part come with a warranty?
Absolutely. This unit is backed by our one-year replacement warranty, giving you peace of mind with your purchase.
