Installation and Post-Install Notes
While this module is designed for a straightforward installation, some vehicles may require additional steps after the part is connected. These are known as ‘relearn’ procedures and can sometimes be necessary to sync all vehicle systems. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated 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: To ensure proper brake light and traction control function, a brake pedal position sensor relearn may be required on certain models.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
