DTC Confirmation Test

NOTE: If DTC confirmation procedure had been previously run, turn ignition off and wait at least 10 seconds before continuing.

Turn ignition on. On scan tool, select DATA MONITOR mode. Observe COOLAN TEMP/S parameter. If parameter is less than 50°F (10°C), start engine and let it idle for 65 minutes. If coolant temperature increases to 50°F (10°C) or more, test result is okay. If 1st trip DTC is detected, go to DIAGNOSTIC PROCEDURE .
