DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at

least 10 seconds before conducting the next test.

TESTING CONDITION:

• Before performing the following procedure, confirm that battery voltage is more than 11 V at idle.

• Always perform the test at a temperature above 

−12°C (10°F)

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

 With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode with CONSULT.

3. Make sure that “COOLAN TEMP/S” indicates between 

−12°C (10°F) to 20°C (68°F).

If not, cool engine down or warm engine up until “COOLAN TEMP/S” indicates between 

−12°C (10°F) to

20

°C (68°F). Then go to the following steps.

4. Fully release accelerator pedal and wait at least 10 seconds.

5. Depress accelerator pedal and wait at least 10 seconds.

6. Check 1st trip DTC.

 With GST

Following the procedure “With CONSULT” above.
Is 1st trip DTC detected?

YES

>> Proceed to 

EC-879, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000009481581

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

5. Also check harness for short to ground.
Is the inspection result normal?

YES

>> Perform the trouble diagnosis for power supply circuit.

NO

>> Repair or replace error-detected parts.

3.

CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR OUTPUT SIGNAL CIRCUIT

1. Disconnect intake manifold runner control valve motor harness connector.

2. Check the continuity between intake manifold runner control valve motor harness connector and ECM

harness connector.

3. Also check harness for short to ground and to power.
Is the inspection result normal?

YES

>> GO TO 4.

NO

>> Repair or replace error-detected parts.

4.

CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR

Check the intake manifold runner control valve motor. Refer to 

EC-880, "Component Inspection"

.

Is the inspection result normal?

YES

>> Check intermittent incident. Refer to 

GI-42, "Intermittent Incident"

.

NO

>> Replace intake manifold assembly. Refer to

.

Component Inspection

INFOID:0000000009481582

1.

CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE

 With CONSULT

1. Turn ignition switch ON.

2. Select “DATA MONITOR” mode with CONSULT.

3. Make sure that “COOLAN TEMP/S” indicates between 

−12°C (10°F) to 20°C (68°F).

If not, cool engine down or warm engine up until “COOLAN TEMP/S” indicates between 

−12°C (10°F) to

20

°C (68°F). Then go to the following steps.

4. Fully release accelerator pedal and make sure that “TUMBLE POS SEN” indicates between 2.8 V to 4.1

V.

5. Depress accelerator pedal and make sure that “TUMBLE POS SEN” indicates between 0.2 V to 1.4 V.

6. Check 1st trip DTC.
