Installation and Post-Install Notes
Installation is straightforward for the DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. Simply disconnect the vehicle’s battery, unbolt the old module, disconnect the wiring harnesses, and connect the new one. While the unit is pre-programmed, some vehicles may require a simple relearn procedure after installation.
- Airbag System Sync: If the airbag light remains on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light and traction control operation.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s non-engine related functions. It controls the power windows, locks, lights, wipers, security system, and HVAC, ensuring all these comfort and convenience features work together properly.
Is this BCM really plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This eliminates the need for dealership programming, making the installation process as simple as swapping the part.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Where is the BCM located on my 2005 Suburban 2500?
On the 2003-2006 Suburban 2500, as well as most compatible GM trucks and SUVs, the BCM is found under the driver’s side of the dashboard, typically attached to a bracket near the steering column.
Do I have to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which saves you the time and hassle of a return shipment.
