NATS SECURITY - VBC LOGIC
APPLIED VEHICLE:2009 – 2011 All Nissan with NATS / Immobilizer System
SERVICE INFORMATION
All model year 2009 – 2011 Nissan 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
