Installation & Post-Install Notes
The BCM is typically located under the driver’s side dashboard, near the steering column, and installation can often be completed in under 10 minutes. While the module is plug-and-play, some vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains on after installation. This is a simple sync procedure that can be performed with most professional-grade scan tools. Similarly, a Brake Pedal Position Relearn may be needed to ensure proper brake light and stability control function. Always consult a service manual for procedures specific to your vehicle.
