A Word From Our Master Tech
“We see these GMT900 platform vehicles all the time. A common mistake during BCM replacement is overlooking a poor ground connection. The main BCM ground is typically located on the A-pillar near the driver’s left foot. Before installing your new module, take a moment to remove, clean, and tighten that ground point. A clean, solid ground is the foundation of a healthy electrical system and can prevent a host of recurring issues. This simple step ensures your new GM 25844480 Body Control Module can perform its job perfectly from day one.”
Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like your power windows, door locks, interior/exterior lights, security system, wipers, and HVAC climate control.
Is this part difficult to install?
Installation is typically straightforward for those with basic mechanical skills. The BCM is usually located under the driver’s side dashboard, near the steering column. The process generally takes less than 15 minutes. Because it’s pre-programmed, no special tools are needed for the initial installation.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and options into the BCM. Without it, the module won’t know how to communicate with your vehicle, leading to incorrect operation of features or a complete failure to function. Our service saves you a mandatory and costly trip to the dealer.
What if my airbag light stays on after installation?
In some cases, particularly if DTC B1001 was present, the new BCM needs to be synced with the airbag system’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a simple sync, not a full reprogramming.
Is there a core charge for this part?
No, there is no core charge. You are not required to return your old, faulty module, which simplifies the repair process for you.
