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 (113°F)?
YES
>> GO TO 3.
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 3.
NO-2 [if it is above 45
°C (113°F)]>>Cool the engine down to the value of “COOLAN TEMP/S” indicates −5°C
(23
°F) and 45°C (113°F). And then GO TO 3.
3.
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.
DTC No.
