Code P1615 Nissan Description

The P1615 Nissan code refers to a NVIS (Nissan Vehicle Immobilizer System) issue involving a difference in the key being used to start the vehicle. The NVIS is a security system that prevents the vehicle from being started without the correct key. When the system detects a difference in the key being used, it triggers this diagnostic trouble code (DTC). This can happen if the key is not programmed correctly, if there is an issue with the key itself, or if there is a problem with the NVIS system.
