NOTE:

In general, the way customers explanation of symptom differs from person to person, so it is important to fully understand the symptom and condition by conducting sufficient interviews. Use "Diagnostic Work Sheet" to systematize all the information for troubleshooting.

  • If there is a problem with the Nissan Ariya vehicle, use "Diagnostic Work Sheet A".

  • Use "Diagnostic Work Sheet B" for problems related to charging, such as "cannot charge", "charging stops halfway", or "warning lamp turns on after charging".

Refer to Diagnostic Work Sheet.

>>

GO TO 7.

PERFORM DTC CONFIRMATION PROCEDURE

Perform DTC CONFIRMATION PROCEDURE for the displayed DTC, and then check that DTC is detected again.

NOTE:

  • Freeze frame data is useful if the DTC is not detected.

  • Perform Component Function Check if DTC CONFIRMATION PROCEDURE does not included corresponded DTC Manual. This simplified check procedure is an effective alternative though DTC cannot be detected during this check.

  • If the result of Component Function Check is NG, it is the same as the detection of DTC by DTC CONFIRMATION PROCEDURE.

Is DTC detected?

YES>>

GO TO 8.

NO>>

Is the malfunction system detected?

YES>>

GO TO 9.

NO>>

DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE

Inspect according to Diagnosis Procedure of the system.

Is a malfunctioning part detected?

YES>>

GO TO 9.

NO>>

Check according to the symptom cause simulation test. Refer to Intermittent Incident.

  2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replacement.

  3. Check DTC. If DTC is displayed, erase it.

>>

GO TO 10.

FINAL CHECK

When DTC was detected in step 3, perform DTC CONFIRMATION PROCEDURE or Component Function Check again, and then check that the malfunction is completely repaired.

When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and check that the symptom is not detected.

Is DTC detected and does symptom remain?

YES-1(DTC is detected)>>

GO TO 8.

YES-2(Symptom remains)>>

GO TO 5.
