Installation & Post-Install Notes
Installation is straightforward, as the BCM is typically located under the driver’s side of the dashboard. Once installed, while the module is pre-programmed, some vehicles may require additional steps for full system integration:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with your existing airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper brake light and traction control operation.
Best of all, there is no core charge for this part. You can keep your old module without the hassle of returning it.
