Installation and Post-Install Considerations
Once you receive your VIN-programmed module, installation is straightforward. However, in some vehicles, additional steps known as ‘relearn procedures’ may be necessary to fully sync the new module with other vehicle systems.
- 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 scan tool.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor recalibration might be required.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
