GET INFORMATION FOR SYMPTOM
Get the detailed information from the customer about the symptom (the condition and the environment when
the incident/malfunction occurred) using the “Diagnostic Work Sheet”. (Refer to
>> GO TO 2.
2.
CHECK DTC
1.
Check DTC.
2.
Perform the following procedure if DTC is displayed.
-
Record DTC and freeze frame data. (Print them out with CONSULT-III or GST.)
-
Erase DTC. (Refer to
EC-102, "Diagnosis Description"
-
Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to
3.
Check related service bulletins for information.
Is any symptom described and any DTC detected?
Symptom is described, DTC is displayed>>GO TO 3.
Symptom is described, DTC is not displayed>>GO TO 4.
Symptom is not described, DTC is displayed>>GO TO 5.
3.
CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer (except MIL ON).
Also study the normal operation and fail safe related to the symptom. Refer to
and
.
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.

4.
CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Also study the normal operation and fail safe related to the symptom. Refer to
and
.
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 6.
5.
PERFORM DTC CONFIRMATION PROCEDURE
Perform DTC CONFIRMATION PROCEDURE for the displayed DTC, and then check that DTC is detected
again.
If two or more DTCs are detected, refer to
EC-519, "DTC Inspection Priority Chart"
and determine trouble
diagnosis order.
NOTE:
• Freeze frame data is useful if the DTC is not detected.
• Perform Component Function Check if DTC CONFIRMATION PROCEDURE is not included on Service
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 CONFIR-
MATION PROCEDURE.
Is DTC detected?
YES
>> GO TO 10.
NO
>> Check according to
GI-40, "Intermittent Incident"
.

is also required for the circuit check in the Diagnostic Procedure. For details, refer to “Circuit Inspection” in
Is malfunctioning part detected?
YES
>> GO TO 11.
NO
>> Monitor input data from related sensors or check voltage of related ECM terminals using CON-
SULT-III. Refer to
11.
REPAIR OR REPLACE THE MALFUNCTIONING PART
1.
Repair or replace the malfunctioning part.
2.
Reconnect parts or connectors disconnected during Diagnostic Procedure again after repair and replace-
ment.
3.
Check DTC. If DTC is displayed, erase it, refer to
EC-102, "Diagnosis Description"
>> GO TO 12.
12.
FINAL CHECK
When DTC was detected in step 2, perform DTC CONFIRMATION PROCEDURE or Component Function
Check again, and then check that the malfunction have been repaired securely.
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 10.
YES-2 >> Symptom remains: GO TO 6.
NO
>> Before returning the vehicle to the customer, erase unnecessary DTC in ECM and TCM (Trans-
mission Control Module) certainly. (Refer to

Diagnostic Work Sheet
INFOID:0000000003387867
DESCRIPTION
There are many operating conditions that lead to the malfunction of
engine components. A good grasp of such conditions can make trou-
bleshooting faster and more accurate.
In general, each customer feels differently about symptoms. It is
important to fully understand the symptoms or conditions for a cus-
tomer complaint.
Utilize a diagnostic worksheet like the WORKSHEET SAMPLE
below in order to organize all the information for troubleshooting.
Some conditions may cause the MIL to illuminate or blink, and DTC
to be detected. Examples:
• Vehicle ran out of fuel, which caused the engine to misfire.
• Fuel filler cap was left off or incorrectly screwed on, allowing fuel to
evaporate into the atmosphere.
