Post-Installation Information
While this BCM is programmed for your VIN, some vehicles may require minor post-installation procedures for full system synchronization. These can typically be performed by a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control function.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions, such as power windows, locks, lights, wipers, security system, and instrument cluster warnings.
Is this BCM difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. On most trucks, it’s located under the steering column. Since we program it to your VIN, the complex software setup is already done for you.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as the programming is essential for the part to work.
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 is on after I install the new BCM?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system. A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
