Why Choose Our Programmed GM Body Control Module?
This isn’t just a replacement part; it’s a complete solution. We take the hassle out of the repair by programming the module with the latest GM software updates specific to your vehicle’s VIN. This critical step ensures that all systems communicate correctly right out of the box. A non-programmed module from a dealership or parts store would require additional labor and specialized tools for programming, adding significant cost and downtime to your repair. Our module is ready for installation the moment you receive it, making it the smartest choice for both DIY mechanics and professional technicians.
Installation and Post-Install Procedures
Installation is straightforward. The BCM is typically located under the driver’s side dashboard, near the steering column. The physical swap takes only a few minutes. However, depending on your vehicle’s configuration, a couple of post-installation steps may be necessary:
- Airbag System Sync: If the airbag warning light remains on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control functionality.
This module is a direct replacement for multiple part numbers, including 15263363, 25835966, 15943678, 20939137, and 22860591. With no core charge, you can complete your repair without the inconvenience of returning the old part.
Frequently Asked Questions
What does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and climate controls.
Is this module truly plug-and-play?
Yes, it is. We program the module to your vehicle’s VIN before shipping, so it’s ready for installation without requiring any additional programming from a dealership.
Where is the BCM located on my truck or SUV?
On most compatible GM models like the Silverado, Tahoe, and Yukon, the BCM is found under the driver’s side dashboard, typically to the left of the steering column.
My airbag light is on after installing the new BCM. What should I do?
This indicates that the BCM needs to be electronically synced with the airbag system’s Sensing and Diagnostic Module (SDM). A technician with a professional scan tool must perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
Do I need to send my old part back?
No. We do not require a core return for this part, which saves you time and shipping costs. You can keep or dispose of your old module.
