EC-166
< BASIC INSPECTION >[QR25DE]
DIAGNOSIS AND REPAIR WORKFLOW
1.GET INFORMATION FOR SYMPTOM
1. 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 EC-168, "Diagnostic
Work Sheet".)
2. Ask if the customer requests I/M examination.
Malfunction information, obtained>>GO TO 2.
No malfunction information, but a request for I/M examination>>GO TO 13.
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 or GST.)
- Erase only DTC of “ENGINE”.
With CONSULT: “How to Erase DTC and 1st Trip DTC” in EC-77, "CONSULT Function"
.
Without CONSULT: “How to Erase Self-diagnostic Results” in EC-74, "On Board Diagnosis Function"
.
- Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Matrix Chart is useful. Refer to EC-527, "Symptom Table"
.)
3. Check related service bulletins for information.
Are any symptoms described and any DTCs detected?
Symptom is described, DTC is detected>>GO TO 3.
Symptom is described, DTC is not detected>>GO TO 4.
Symptom is not described, DTC is detected>>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-s afe related to the symptom. Refer to EC-533, "Description"
and EC-
101, "Fail Safe".
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and the condition when the symptom is detected.
>> GO TO 5.
4.CONFIRM THE SYMPTOM
Try to confirm the symptom described by the customer.
Also study the normal operation and fail-safe re lated to the symptom. Refer to Refer to EC-533, "Description"
and EC-101, "Fail Safe".
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 disp layed DTC, and then check that DTC is detected
again.
If two or more DTCs are detected, refer to EC-104, "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 CONFIR MATION PROCEDURE is not included on Service
Manual. This simplified check procedure is an effect ive 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-43, "Intermittent Incident"
.

YES >> GO TO 11.
NO >> GO TO 9.
9.DETECT MALFUNCTIONING SY STEM BY SYMPTOM TABLE
Detect malfunctioning system according to EC-527, "Symptom Table"
based on the confirmed symptom in
step 4, and determine the trouble diagnosis or der based on possible causes and symptoms.
>> GO TO 10.
10.DETECT MALFUNCTIONING PART BY DIAGNOSIS PROCEDURE
Inspect according to Diagnosis Procedure of the system.
NOTE:
The Diagnosis Procedure in EC section described based on open circuit inspection. A short circuit inspection
is also required for the circuit check in the Diagnosis Procedure. For details, refer to GI-46, "Circuit Inspec-
tion".
Is a malfunctioning part detected?
YES >> GO TO 11.
NO >> Monitor input data from related sensors or check voltage of related ECM terminals using CON-
SULT. Refer to EC-88, "Reference Value"
.
11 .REPAIR OR REPLACE THE MALFUNCTIONING PART
1. Repair or replace the malfunctioning part.
2. Reconnect parts or connectors disconnected during Diagnosis Procedure again after repair and replace-
ment.
3. Check DTC. If DTC is displayed, erase it. Refer to the following.
With CONSULT: “How to Erase DTC and 1st Trip DTC” in EC-77, "CONSULT Function"
.
Without CONSULT: “How to Erase Self-diagnostic Results” in EC-74, "On Board Diagnosis Function"
.
>> GO TO 12.
12.FINAL CHECK
When DTC was detected in step 2, perform DTC CO NFIRMATION PROCEDURE or Component Function
Check again, and then check that the malfunction have been completely repaired.
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.
