Conditions for Clearing the MIL/DTC

A history DTC will clear if no fault conditions have been detected for 40 warm-up cycles.
A warm-up cycle occurs when the coolant temperature has risen 22°C (40°F) from the start-up coolant temperature and the engine coolant temperature (ECT) exceeds 70°C (160°F) during the same ignition cycle.
Use the scan tool Clear Information function.
