Post-Installation Information
While this module is designed to be a straightforward installation, some vehicles may require a final relearn procedure. This is standard for BCM replacements. Please be aware of the following potential steps:
- 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 operation, a brake pedal position sensor relearn might be necessary.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
