DTC CONFIRMATION PROCEDURE


1. PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
1.Turn ignition switch OFF and wait at least 10 seconds.
2.Turn ignition switch ON.
3.Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 11 V when engine is running.
- GO TO 2.

2. PERFORM DTC CONFIRMATION PROCEDURE

1.Turn ignition switch ON and wait at least 2 seconds.
2.Start engine and let it idle for 5 seconds.
3.Check DTC.
Is DTC detected?
YES- Proceed to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL

1.Check the voltage between ECM harness connector terminals.





Is the inspection result normal?
YES- GO TO 4.
NO- GO TO 2.

2. CHECK THROTTLE CONTROL MOTOR RELAY POWER SUPPLY CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect ECM harness connector.
3.Disconnect IPDM E/R harness connector.
4.Check the continuity between IPDM E/R harness connector and ECM harness connector.





5.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 3.
NO- Repair open circuit, short to ground or short to power in harness or connectors.

3. CHECK THROTTLE CONTROL MOTOR RELAY INPUT SIGNAL CIRCUIT

1.Check the continuity between IPDM E/R harness connector and ECM harness connector.





2.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- Perform the trouble diagnosis for power supply circuit.
NO- Repair open circuit, short to ground or short to power in harness or connectors.

4. CHECK THROTTLE CONTROL MOTOR OUTPUT SIGNAL CIRCUIT FOR OPEN OR SHORT

1.Turn ignition switch OFF.
2.Disconnect electric throttle control actuator harness connector.
3.Disconnect ECM harness connector.
4.Check the continuity between electric throttle control actuator harness connector and ECM harness connector.





5.Also check harness for short to ground and short to power.
Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace malfunctioning part.

5. CHECK ELECTRIC THROTTLE CONTROL ACTUATOR VISUALLY

1.Remove the intake air duct. Refer to "Exploded View" Exploded View.





2.Check if foreign matter is caught between the throttle valve (1)
and the housing.
-Electric throttle control actuator (2)
-White arrow indicates : Vehicle front

Is the inspection result normal?
YES- GO TO 6.
NO- Remove the foreign matter and clean the electric throttle control actuator inside, refer to {LINK_TO_MANY:0000000008689547}{LINK_TO_MANY:0000000007989923}, "Exploded
View", and then perform throttle valve closed position learning. Refer to "Description" Description.

6. CHECK THROTTLE CONTROL MOTOR

Check throttle control motor. Refer to "Component Inspection" .
Is the inspection result normal?
YES- GO TO 7.
NO- Replace electric throttle control actuator. Refer to "Exploded View" Exploded View.

7. CHECK INTERMITTENT INCIDENT

Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
Is the inspection result normal?
YES- Replace electric throttle control actuator. Refer to "Exploded View" Exploded View.
NO- Repair or replace error-detected parts.


Component Inspection


1. CHECK THROTTLE CONTROL MOTOR

1.Turn ignition switch OFF.
2.Disconnect electric throttle control actuator harness connector.
3.Check resistance between electric throttle control actuator terminals as per the following.





Is the inspection result normal?
YES- INSPECTION END
NO- Replace electric throttle control actuator. Refer to "Exploded View" Exploded View.
