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 of “ENGINE” using CONSULT. 6. Check the following. 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 fol- lowing steps. NOTE: • Do not turn ignition switch OFF. • If it is supposed to need a long period of time, do not deplete the battery. 7. Start engine and let it idle for 5 minutes. 8. Check 1st trip DTC. With GST Follow the procedure “With CONSULT” above. YES >> Proceed to . NO >> GO TO 5. 5. PERFORM COMPONENT FUNCTION CHECK (FOR MALFUNCTION B) Perform component function check. Refer to EC-318, "Component Function Check" . NOTE: Use the component function check to check the overall function of the EOT sensor circuit. During this check, a 1st trip DTC might not be confirmed. YES >> INSPECTION END NO >> Proceed to . 6. PRECONDITIONING If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce- dure before conducting the next test. 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.

PERFORM DTC CONFIRMATION PROCEDURE B 1. Start engine and let it idle for 60 minutes. 2. Move the vehicle to a cool place. NOTE: Cool the vehicle in an environment of ambient air temperature between −10°C (14°F) and 35°C (95°F). 3. Turn ignition switch OFF and soak the vehicle for 12 hours. CAUTION: Never turn ignition switch ON during soaking. NOTE: The vehicle must be cooled with the hood open.
