Diagnostic Test
- ENGINE COOLANT INSPECTION NOTE:
This DTC will set if the engine cools quicker than is should compared to engine off times. If the customer washed a hot engine with the engine off, a One Trip Failure will set. If the vehicle is parked in a highly ventilated area or has a large fan blowing on it which might cause the engine to cool quicker than expected this DTC may set.
WARNING:Do not remove or loosen the radiator cap with the system hot and under pressure. Serious burns from coolant can occur.
