Cooling System Malfunction

Cause of DTC

The execution time is once per drive cycle and the duration time is dependent on driving conditions. Malfunction determination 1: If the difference between the current measured coolant temperature at the radiator (ECT 2) and the initial coolant temperature at the radiator (ECT 2) is at least 21 ºF (12 ºC) when the calculated coolant temperature at the engine (ECT 1) reaches 159 ºF (71 ºC), a malfunction is detected (thermostat stuck open); or if the coolant temperature at the radiator (ECT 2) only reaches 68 ºF (20 ºC), a malfunction is detected (thermostat malfunction). Malfunction determination 2: When the calculated engine coolant temperature (ECT 1) reaches 158 ºF (70 ºC) before the measured engine coolant temperature (ECT 1) reaches 158 ºF (70 ºC), a malfunction is detected. NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot.
