DETAILED FLOW
1.
INTERVIEW FROM THE CUSTOMER
Clarify customer complaints before inspection. First of all, perform an interview utilizing
and reproduce the symptom as well as fully understand it. Ask customer about his/her complaints
carefully. Check symptoms by driving vehicle with customer, if necessary.
CAUTION:
Customers are not professional. 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 the interview. Also check that the symptom is not caused by fail-safe mode. Refer to
"Fail-Safe (Chassis Control Module)"
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.
Perform “Self Diagnostic Result“ for “CHASSIS CONTROL“.
Is DTC detected?
YES
>> Record or print self-diagnosis results and freeze frame data (FFD). GO TO 4.
NO
>> Inspection End.
4.
RECHECK THE SYMPTOM
With CONSULT
Perform DTC confirmation procedures for the malfunctioning system.
NOTE:
If some DTCs are detected at the some time, determine the order for performing the diagnosis based on
231, "DTC Inspection Priority Chart"
.
Is DTC detected?
YES
>> GO TO 5.
NO
>> Check harness and connectors based on the information obtained by the interview. Refer to
210, "Precautions for Harness Repair"
.
5.
REPAIR OR REPLACE MALFUNCTIONING PARTS
1.
Repair or replace malfunctioning parts.
2.
Reconnect part or connector after repairing or replacing.
3.
When DTC is detected, erase “Self Diagnostic Result“ for “CHASSIS CONTROL”.
>> GO TO 6.
6.
FINAL CHECK
With CONSULT
1.
Check the reference value for “CHASSIS CONTROL”.
2.
Recheck the symptom and check that the symptom is not reproduced on the same conditions.

Diagnostic Work Sheet
INFOID:0000000010416982
Description
• In general, customers have their own criteria for a symptom. Therefore, it is important to understand the
symptom and status well enough by interviewing the customer about the symptom 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.
