- Study the relationship between the cause detected by DTC and the symptom described by the customer.
(Symptom Table is useful. Refer to EC-487, " Symptom Table " .)

Verify relation between the symptom and t he condition when the symptom is detected.
>> GO TO 5. Description " and
EC- 472, " Fail Safe " .
Diagnosis Work Sheet is useful to verify the incident.
Verify relation between the symptom and t he condition when the symptom is detected.
>> GO TO 6. 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 CONF IRMATION 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 Intermittent Incident according to EC-120, " Diagnosis Procedure " .

NO >> GO TO 9. Symptom Table " based on the confirmed symptom in
step 4, and determine the trouble diagnosis order based on possible causes and symptom.
>> GO TO 10. 25, " How to Perform Efficient Diagnosis for an Electrical Incident " .
Is malfunctioning part detected? YES >> GO TO 11.
NO >> Monitor input data from related sensors or check the voltage of related ECM terminals using CON-
SULT-III. Refer to EC-461, " Reference Value " .
