>> 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.

.
• Check crankshaft position sensor (POS) and circuit. Refer to EC-326, "DTC Logic"
.
Is the inspection result normal?
YES >> GO TO 9.
NO >> Repair or replace. Then GO TO 4
9.CHECK ECM FUNCTION
1. Substitute another known-good ECM to check ECM f unction. (ECM may be the cause of an incident, but
this is a rare case.)
2. Perform initialization of NVIS (NATS) system and regi stration of all NVIS (NATS) ignition key IDs. Refer to
SEC-66, "ECM : Work Procedure"
.
