GET INFORMATION FOR SYMPTOM

EC-129, "Diagnostic Work

Sheet"

.)

>> GO TO 2.

CHECK DTC IN ECM

1. Check DTC in ECM.

2. If a DTC is detected, perform the following steps, and after this, erase DTC.

-

Print (or write down) the detected DTC and freeze frame data.

-

Check DTC logic.

-

Study the relationship between the cause detected by DTC and the symptom described by the customer.

3. Check related Service Bulletins.
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.

Also study the normal operation and fail-safe related to the symptom. Refer to 

EC-473, "Symptom Table"

 and

EC-90, "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.

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-93, "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 7.

NO

>> Check SPORT mode system. Refer to 

DMS-57, "Component Function Check"

.

DETECT MALFUNCTIONING PART BY SYMPTOM DIAGNOSIS

Detect malfunctioning system according to Symptom Diagnosis based on the confirmed symptom in step 4,

and determine the trouble diagnosis order based on possible causes and symptoms.
Is the symptom described?

YES

>> GO TO 7.

NO

>> Monitor input data from related sensors or check voltage of related ECM terminals using CON-

SULT. Refer to 

EC-77, "Reference Value"

.
