Installation and Post-Install Notes
Installation is typically simple, often taking just a few minutes. The BCM is usually located under the driver’s side dashboard or behind the center dash panel. Always disconnect the vehicle’s battery before swapping the module. While this module is designed for plug-and-play operation, some vehicles may require a post-installation procedure. If your airbag light is on after installation, a technician will need to perform an ‘SDM Primary Key Setup’ with a professional scan tool. In some cases, a ‘Brake Pedal Position Relearn’ may also be necessary. Always consult your vehicle’s service manual for specific instructions.
