DTC Confirmation Test

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.
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 does not increase 50°F (10°C), diagnose and repair cooling system fault. If coolant temperature increases to 50°F (10°C) or more, check for 1st trip DTC. If 1st trip DTC is detected, go to DIAGNOSTIC PROCEDURE . If 1st trip DTC is not detected, system is okay.
