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
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
.
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.
