Installation and Post-Install Notes
Installation is straightforward for anyone with basic mechanical skills. Simply locate your old BCM, disconnect the battery, swap the modules, and reconnect everything. However, on modern vehicles, some additional steps may be required to sync the new module with other 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-grade scan tool. This is a security measure to ensure the airbag system is correctly communicating with the new BCM.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.
- No Core Charge: You are not required to send your old module back. There is no core charge associated with this purchase.
