The BCM acts as the central hub for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. Don’t let a faulty module keep your truck off the road. This is the simple, reliable solution to restore full functionality.

Important Post-Installation Information
While this module is programmed for a straightforward installation, some vehicles may require additional steps to sync with other onboard systems. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is on after installation, a simple “Setup SDM Primary Key in BCM” procedure is needed. This requires a professional-grade scan tool to sync the BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine-related electronic features. This includes power windows, locks, interior and exterior lighting, the security system, wipers, and more. It’s the brain behind your vehicle’s comfort and convenience accessories.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. The BCM is typically located under the steering column or in the center dash area. It involves disconnecting the battery, removing a few trim panels, and swapping the module. Since our unit comes pre-programmed, no special computer tools are needed for the basic installation.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as the programming is specific to your exact vehicle.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
