DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait atle-
ast 10 seconds before conducting the next test.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10 V at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

With CONSULT-III

1.

Turn ignition switch ON.

2.

Check “COOLAN TEMP/S” in “DATA MONITOR” mode with CONSULT-III.

3.

Confirm “COOLAN TEMP/S” value is within the range listed below.

If the value is out of range, park the vehicle in a cool place and allow the engine temperature to stabilize.

CAUTION:

Do not attempt to lower the engine coolant temperature with a fan or means other than ambient air.
Doing so may produce an inaccurate diagnostic result.

4.

Start engine and let it idle monitoring “COOLAN TEMP/S” value. When the “COOLAN TEMP/S” value
reaches 70

°

C (158

°

F), immediately go to the next step.

5.

Drive the vehicle for at least 150 consecutive seconds under the following conditions.

CAUTION:

Always drive vehicle at a safe speed.

6.

Stop the engine and let it idle for at least 20 seconds.

7.

Check 1st trip DTC.

With GST

Follow the procedure “With CONSULT-III” above.
Is 1st trip DTC detected?

YES

>> Go to 

EC-204, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.
