With Consult-II

Turn ignition switch ON.
Check "COOLAN TEMP/S" in "DATA MONITOR" mode with CONSULT-II and confirm it is within the range listed below.
COOLAN TEMP/S : Less than 40°C (104°F)

If the value is out of range, park the vehicle in a cool place and allow the engine temperature to stabilize. Do not attempt to lower the coolant temperature with a fan or means other than ambient air. Doing so may produce an inaccurate diagnostic result.
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.
