Installation and Post-Install Considerations
The BCM is typically located under the steering column. While installation is a direct swap, some vehicles may require additional steps after the new module is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM acts as the brain for your vehicle’s body electronics. It controls functions like power windows, locks, lights, the security system, wipers, and the instrument cluster.
Is this part difficult to install?
The physical installation is straightforward for someone with basic mechanical skills, as it’s typically located under the driver’s side dashboard and involves unplugging the old unit and plugging in the new one. However, be aware of the potential post-install procedures mentioned above.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship the module until we receive this information, as the programming is essential for it to work in your truck.
Do I need to return my old BCM?
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 this?
This indicates the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade diagnostic tool to resolve this.
