Diagnosis and Repair Work Flow

Work Flow

OBTAIN INFORMATION ABOUT SYMPTOM

Refer to Diagnostic Work Sheet and interview the customer to obtain the malfunction information (conditions and environment when the malfunction occurred) as much as possible when the customer brings in the Nissan Ariya vehicle. Refer to Diagnostic Work Sheet.

GO TO 2.

CHECK DTC IN INVERTER (REAR)

Before checking the malfunction, check whether any DTC exists.
If DTC exists, perform the following operations.
- Record the DTC and freeze frame data. (Print out the data using CONSULT and affix them to the Work Order Sheet.)
- Erase DTCs.
- Check the relationship between the cause that is clarified with DTC and the malfunction information described by the customer.

Do malfunction information and DTC exist?

Malfunction information and DTC exists. >>

REPRODUCE MALFUNCTION SYMPTOM

Check any malfunction described by a customer, except those with DTC on the Nissan Ariya vehicle.

Also investigate whether the symptom is a fail-safe or normal operation. Refer to Fail-safe.

When a malfunction symptom is reproduced, the question sheet is effective. Refer to Diagnostic Work Sheet.

Verify the relationship between the symptom and the conditions in which the malfunction described by the customer occurs.

REPRODUCE MALFUNCTION SYMPTOM

Check the malfunction described by the customer on the Nissan Ariya vehicle.

Also investigate whether the symptom is a normal operation. Refer to Protection Function.

When a malfunction symptom is reproduced, the question sheet is effective. Refer to Diagnostic Work Sheet.

Verify the relationship between the symptom and the conditions in which the malfunction described by the customer occurs.

GO TO 7.

PERFORM “DTC CONFIRMATION PROCEDURE”

Perform “DTC CONFIRMATION PROCEDURE” of the appropriate DTC to check if DTC is detected again.

Refer to DTC Inspection Priority Chart when multiple DTCs are detected, and then determine the order for performing the diagnosis. Refer to DTC Inspection Priority Chart.

NOTE:

If no DTC is detected, refer to the freeze frame data.

Is any DTC detected?

YES>>

GO TO 6.

NO>>

Check according to Intermittent Incident. Refer to Intermittent Incident.

REPAIR OR REPLACE THE MALFUNCTIONING PARTS

Repair or replace the detected malfunctioning parts.

Reconnect parts or connector after repairing or replacing, and then erase DTC if necessary.

GO TO 7.

FINAL CHECK

Perform “DTC CONFIRMATION PROCEDURE” again to make sure that the repair is correctly performed.

Check that malfunctions are not reproduced when obtaining the malfunction information from the customer, referring to the symptom inspection result in step 3 or 4.

Is DTC or malfunction symptom reproduced?

YES>>

GO TO 2.

NO>>

Before delivering the Nissan Ariya vehicle to the customer, make sure that DTC is erased.

Diagnostic Work Sheet

DESCRIPTION

By understanding those conditions properly, a quick and exact diagnosis can be achieved.

In general, customers have their own criteria for a problem. Therefore, it is important to understand the symptom and status well enough by asking the customer about the concerns carefully. In order to systemize all the information for the diagnosis, prepare the question sheet referring to the question points.
