Installation & Post-Install Notes
Installation is straightforward for those with basic mechanical skills. The BCM is typically located under the driver’s side dashboard, near the steering column. While the module is plug-and-play, some vehicles may require additional steps for full system integration.
Post-Installation Procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure brake lights and traction control work correctly.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance. Checking for and correcting any grounding issues during installation can prevent future problems.
