P1610 on 2003-2009 Nissan 350Z — NATS (Nissan Anti-Theft System) Malfunction
1 vehicles · 1 makes · $300-$1,900 repair
Most Reported On
P1610 is an OBD-II diagnostic trouble code meaning “NATS (Nissan Anti-Theft System) Malfunction.” This is a Nissan-specific code related to the NATS (Nissan Anti-Theft System) immobilizer, the security system that requires a recognized key or transponder before the engine is allowed to start and run. The code sets when the engine control module and the immobilizer (BCM/IMMU) cannot properly communicate or fail to authenticate the key. When this happens, the system blocks fuel and/or spark as an anti-theft measure, so the engine may crank but not start, often with a flashing security light. It generally points to a key, immobilizer, or communication issue rather than a mechanical engine fault. This code is most commonly reported on 2003-2009 Nissan 350Z, with repair costs ranging from $300 to $1,900.
