step 4, and determine the trouble diagnosis or der based on possible causes and symptom.
>> 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 “Circuit Inspection” in GI-
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 c heck the voltage of related ECM terminals using CON-
SULT-III. Refer to EC-454, "
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 “How to Erase DTC and 1st Trip DTC” in EC-84, "
Diag-
nosis Description".
>> 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 make sure that the malfunction have been repaired securely.
When symptom was described from the customer, refer to confirmed symptom in step 3 or 4, and make sure
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.
