DTC Confirmation Procedure

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

  1. Turn ignition switch OFF and wait at least 10 seconds.

  2. Turn ignition switch ON.

  3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

  • Perform DTC CONFIRMATION PROCEDURE when the fuel is between 1/4 and 3/4 full, and Nissan Ariya vehicle is placed on flat level surface.

  • Always perform test at a temperature of 5 to 60°C (41 to 140°F).

  • Cool the Nissan Ariya vehicle so that engine coolant temperature becomes same level as ambient temperature.
