Installation and Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column, making replacement a straightforward process. However, after installing the new module, certain systems may require recalibration. If the airbag light remains on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, a ‘Brake Pedal Position Relearn’ may be necessary on some models to ensure proper brake light and stability control operation. Always consult a service manual for procedures specific to your vehicle.
Frequently Asked Questions
What does a Body Control Module do on a Silverado 2500?
The BCM is a computer that manages and controls many of your truck’s non-engine related electronic functions, such as power windows, door locks, interior and exterior lighting, wipers, the security system, and the HVAC system.
Is this BCM ready to install out of the box?
Yes. We pre-program the module to your vehicle’s VIN before shipping, so it is ready for a plug-and-play installation without requiring a trip to the dealership for programming.
Where is the BCM located on a 2009 Silverado 2500?
The BCM is located inside the cabin, typically under the driver’s side of the dashboard, near the steering column and fuse panel.
Will this fix my airbag light with code B1001?
This module will resolve the fault within the BCM that causes the B1001 code. However, after installation, you may need a professional scan tool to perform an ‘SDM key update’ or ‘Airbag System Sync’ to clear the light from the dash.
