SERVICE INFORMATION
All model year 2009 - 2011 Infiniti vehicles equipped with NATS / Immobilizer system have the new VBC (Validate Before Crank) starter relay logic.
VBC (Validate Before Crank) Logic:
- The BCM will make sure that a valid (registered) key is being used before engaging the starter relay. If the key is not authenticated the starter will not operate.
- If the engine cranks, the issue is not related to NATS. Do not replace NATS components (BCM, I-Key, FOB Reader or RF Receiver). Refer to ASIST for further diagnostic information as needed.
