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 11 V or more at idle.

GO TO 3.

1. Start engine and warm it up to normal operating temperature.
2. Turn ignition switch OFF and wait at least 10 seconds.
3. Turn ignition switch ON.
4. Turn ignition switch OFF and wait at least 10 seconds.
5. Start engine and let it idle for 5 minutes and 10 seconds.
6. Check 1st trip DTC.

Is 1st trip DTC detected?

YES

Refer to DTC Diagnosis Procedure .

NO

GO TO 4.

With CONSULT

1. Select "DATA MONITOR" mode with CONSULT.
2. Check that "COOLAN TEMP/S" indicates above 60 deg. C (140 deg. F).

   If it is above 80 deg. C (176 deg. F), go to the following steps.

   If it is below 60 deg. C (140 deg. F), warm engine up until "COOLAN TEMP/S" indicates more than 60 deg. C (140 deg. F). Then perform the following steps.

3. Turn ignition switch OFF and soak the vehicle in a cool place.
4. Turn ignition switch ON.
   NOTE: Do not turn ignition switch OFF until step 8.
5. Select "DATA MONITOR" mode with CONSULT.
6. Check the following.

   COOLAN TEMP/S	Below 40 deg. C (104 deg. F)
   INT/A TEMP SE	Below 40 deg. C (104 deg. F)
   Difference between "COOLAN TEMP/S" and "INT/A TEMP SE"	Within 6 deg. C (11 deg. F)

   If they are within the specified range, perform the following steps.

   If they are out of the specified range, soak the vehicle to meet the above conditions. Then perform the following steps.

   NOTE:

   • Do not turn ignition switch OFF.
   • If it is supposed to need a long period of time, do not deplete the battery.
