DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
TESTING CONDITION:
Before performing the following procedure, confi rm that battery voltage is 10 V or more at idle.
With CONSULT
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.
4. Turn ignition switch ON.
5. On the CONSULT screen, select “ENGINE” >> “DATA MONITOR” >> “COOLAN TEMP/S”.
6. Check “COOLAN TEMP/S” indication value.
With GST
Follow the procedure “With CONSULT” above.
Is the value of
“COOLAN TEMP/S”−5°C (23°F) and 45°C (11 3°F)?
YES >> GO TO 2.
NO-1 [if it is below − 5 °C (23 °F)]>>Warm up the engine until the value of “COOLAN TEMP/S” indicates −5 °C
(23 °F) and 45 °C (113 °F). And then GO TO 2.
NO-2 [if it is above 45 °C (113 °F)]>>Cool the engine down to the val ue of “COOLAN TEMP/S” indicates −5 °C
(23 °F) and 45 °C (113 °F). And then GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
1. Turn ignition switch OFF and wait at 10 seconds.
2. Turn ignition switch ON.
3. Set the selector lever in N range.
4. Start the engine and let it idle for 20 seconds or more.
5. Check 1st trip DTC.
Is 1st trip DTC detected?
YES >> Proceed to EC-394, "Diagnosis Procedure"
NO >> INSPECTION END

With CONSULT
1. Turn ignition switch ON.
2. On the CONSULT screen, select “ENGINE” >> “DATA MONITOR” >> “COOLAN TEMP/S”.
3. Check that the “COOLAN TEMP/S” indication value is between −5 °C (23 °F) and 45 °C (113 °F).
4. Start engine and wait at least 5 seconds.
5. On the CONSULT screen, select “ENGINE” >> “DATA MONITOR” >> “INT/V TIM (B1)”.
6. Check that the data monitor item indicates as follows:
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI-43, "Intermittent Incident".
NO >> GO TO 3.
3.CHECK OIL PRESSURE WARNING LAMP
1. Start engine.
2. Check that oil pressure warning lamp is not illuminated.
Is oil pressure warning lamp illuminated?
YES >> Refer to LU-9, "Inspection".
NO >> GO TO 4.
4.CHECK INTAKE VALVE TIMING INTERMEDIA TE LOCK CONTROL SOLENOID VALVE
Perform Component Inspection of the intake valve timi ng intermediate lock control solenoid valve. Refer to
EC-397, "Component Inspection (Intake Valve Timing Intermediate Lock Control Solenoid Valve)"
.
Is the inspection result normal?
YES >> GO TO 5.
NO >> Repair or replace error-detected parts.
5.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Perform Component Inspection of the intake va lve timing control solenoid valve. Refer to EC-396, "Compo-
nent Inspection (Intake Valve Timing Control Solenoid Valve)".
Is the inspection result normal?
YES >> GO TO 6.
NO >> Repair or replace error-detected parts.
6.CHECK CRANKSHAFT POSITION SENSOR
Perform Component Inspection of the cr ankshaft position sensor. Refer to EC-397, "Component Inspection
(Crankshaft Position sensor)".
Is the inspection result normal?
YES >> GO TO 7.
NO >> Repair or replace error-detected parts.
7.CHECK CAMSHAFT PO SITION SENSOR
Perform Component Inspection of the camshaft position sensor. Refer to EC-398, "Component Inspection
(Camshaft position sensor)".
Is the inspection result normal?
