Installation and Post-Install Information
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part 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 may be needed 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 is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories not related to the engine, such as power windows, locks, lights, security system, and climate controls.
Why do you need my VIN?
We require your Vehicle Identification Number (VIN) to program the BCM with the specific software and settings for your truck’s exact features and options. This ensures the module works correctly right out of the box.
Is this part difficult to install?
The physical installation is typically simple, involving unplugging the old module and plugging in the new one. It’s usually located under the driver’s side dashboard. However, as noted, some vehicles may require additional electronic relearn procedures with a scan tool.
What happens if my airbag light comes on after installation?
This indicates the new BCM needs to be electronically synced with your vehicle’s airbag system. A technician with a professional diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
