Installation and Post-Install Notes
While this module is designed for plug-and-play installation, some vehicles may require minor post-installation procedures to sync all systems correctly. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. 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 to prevent issues with the traction control system.
- No Core Charge: You are not required to send your old BCM back. Keep your original module without any extra fees or hassle.
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 functions not related to the engine, such as power windows, locks, lights, security system, and climate controls.
Is this BCM truly plug-and-play?
Yes, for most vehicles. Because we program it to your VIN, it’s ready to install out of the box without needing a trip to the dealer. However, as noted, some vehicles may require simple relearn procedures for the airbag or brake systems.
How do I provide my VIN for programming?
You can add your vehicle’s 17-digit VIN to the notes section during checkout. If you forget, we will contact you via email after your purchase to request it before we can program and ship your module.
What tools are needed for the post-install procedures?
The Airbag System Sync and Brake Pedal Position Relearn procedures require a professional-grade bidirectional diagnostic tool, like a Tech 2 or similar high-end scanner. Most local repair shops have this equipment.
Do I need to send my old part back?
No. This product comes with no core charge. You can keep your original BCM.
