Nissan Xterra security indicator light activates when the vehicle is off on Nissan Xterra

Some Nissan Xterra owners report experiencing issues with the security indicator light activating while the vehicle is off, which may signal problems with the security system. If the light stays on continuously, it could indicate an electrical issue, such as a faulty fuse or battery, or a computer malfunction. Additionally, while a brief flash during the "bulb check" process is normal, a solid security light with the key in the "on" position might suggest a NATS (Nissan Anti-Theft System) issue. Owners also note that if the key light flashes when the key is not in the ignition, it likely means the alarm and immobilizer system are active. It is important for owners to check for potential security system issues promptly and seek professional assistance if the problem persists to ensure the vehicle's security systems remain functional.
