DETAILS OF TROUBLE DIAGNOSIS FLOWCHART

1.

COLLECT THE INFORMATION FROM THE CUSTOMER

It is also important to clarify customer concerns before starting the inspection. First of all, perform an interview
utilizing 

PB-38, "Diagnostic Work Sheet"

 and reproduce the symptom as well as fully understand it. Depending

on the situations, drive the vehicle with the customer and check the symptom.

CAUTION:

Customers are not professionals. Never guess easily like “maybe the customer means that...,” or
“maybe the customer mentions this symptom”.

>> GO TO 2.

2.

CHECK SYMPTOM

Reproduce the symptom that is indicated by the customer, based on the information from the customer
obtained by interview. Also check that the symptom is not caused by fail-safe mode. Refer to 

PB-28, "Fail-

Safe"

.

CAUTION:

When the symptom is caused by normal operation, fully inspect each portion and obtain the under-
standing of customer that the symptom is not caused by a malfunction.

>> GO TO 3.

3.

PERFORM SELF-DIAGNOSIS

With CONSULT

1.

Turn the ignition switch OFF to ON.

CAUTION:

Be sure wait of 10 seconds after turning ignition switch OFF or ON.

2.

Perform self-diagnosis for “EHS/PKB”.

Is DTC detected?

YES

>> Record or print self-diagnosis results and freeze frame data (FFD). GO TO 4.

NO

>> GO TO 6.

4.

RECHECK THE SYMPTOM

With CONSULT

1.

Erase self-diagnostic result for “EHS/PKB”.

2.

Turn the ignition switch OFF to ON.

CAUTION:

Be sure wait of 10 seconds after turning ignition switch OFF or ON.

3.

Perform DTC confirmation procedure for error-detected system.
NOTE:
If some DTCs are detected at the some time, determine the order for performing the diagnosis based on

PB-29, "DTC Inspection Priority Chart"

.

Is DTC detected?

YES

>> GO TO 5.

NO

>> Check harness and connectors based on the information obtained by interview. Refer to 

GI-44,

"Intermittent Incident"

.

5.

REPAIR OR REPLACE ERROR-DETECTED PART

1.

Repair or replace error-detected parts.

2.

Reconnect part or connector after repairing or replacing.

3.

When DTC is detected, erase self-diagnostic result for “EHS/PKB”.

Diagnostic Work Sheet

INFOID:0000000010833856

DESCRIPTION

• 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 his/her concerns carefully. To systemize all
the information for the diagnosis, prepare the interview sheet referring to the interview points.

• In some cases, multiple conditions that appear simultaneously may cause a DTC to be detected.
