Installation & Post-Install Notes
After installing the BCM, some vehicles may require additional relearn procedures. These are simple steps that can often be performed with a capable bi-directional scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration may be necessary on some models to ensure correct brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine-related functions, such as power windows, locks, lights, wipers, security system, and remote keyless entry.
Do I need to have this module programmed?
No. We program the module for you before shipping. Just provide your vehicle’s 17-digit VIN when you place your order, and it will arrive ready to be installed.
Where is the BCM located on my vehicle?
On most compatible Sierra and Silverado pickups, the BCM is located under the driver’s side of the dashboard, near the steering column. On Express and Savana vans, it is typically found in the center of the dash area.
What if my airbag light turns on after I install it?
This is a normal possibility. The new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
