Before replacing your BCM, always perform a thorough check of the main vehicle grounds, especially the ground strap from the engine to the chassis. A poor ground connection can mimic the symptoms of a failed BCM and can cause premature failure of the new module if not corrected. A simple check can save you time and money.

- ✔ An active airbag warning light, often accompanied by DTC B1001.
- ✔ Malfunctioning interior or exterior lights (headlights, taillights, dome lights).

Installation and Post-Install Considerations
Installation is simple for the average DIY mechanic. The BCM is typically located under the driver’s side dashboard, near the steering column. While the module is plug-and-play, certain vehicles may require a ‘Setup SDM Primary Key in BCM’ procedure if the airbag light remains illuminated after installation. This is not a programming step but a security handshake that can be performed with most professional-grade diagnostic tools. Similarly, a Brake Pedal Position relearn may be necessary. There is no core charge, so you can keep your old part without any hassle.
