Diagnosis Procedure: Notes

WARNING: This page is about a different car, the 2020 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Engine does not start when push-button ignition switch is pressed while carrying Intelligent Key.

NOTE:
  • Before starting diagnosis check that vehicle condition is as shown in "Conditions of vehicle", and check each symptom.
  • The engine start function, door lock function, power distribution system, and NATS-IVIS/NVIS in the Intelligent Key system are closely related to each other regarding control. The vehicle security function can operate only when the door lock and power distribution system are operating normally.
