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
