Frequently Asked Questions
What exactly 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 your interior and exterior lights, power windows, door locks, climate control (HVAC), security system, and wipers. When it fails, you experience the strange electrical issues this part is designed to fix.
Why is VIN programming so important?
VIN programming loads your vehicle’s specific software and security information onto the module. Without it, the BCM won’t be able to communicate correctly with the other modules in your vehicle, like the Engine Control Module (ECM) or Airbag Module (SDM). Our pre-programming makes the installation plug-and-play, saving you a mandatory and costly trip to the dealership.
How difficult is the installation?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is typically located under the driver’s side dashboard near the steering column. The process usually takes less than 15 minutes. The most important part is ensuring the new module is programmed, which we handle for you before shipping.
What if the airbag light stays on after I install it?
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 function, not a full reprogramming.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which simplifies the process and gets your vehicle repaired faster.
Will this BCM fit my vehicle?
This module is a direct replacement for a wide range of 2007-2013 GM trucks and SUVs, including the Silverado, Sierra, Tahoe, Yukon, Suburban, and Escalade. It interchanges with numerous part numbers, including 25971917, 25844480, and 22860591. Please verify the part number or use the fitment chart to confirm compatibility.
