•  To prevent the engine coolant temperature from rising due to a problem such as overloaded towing, severe high-load driving, or the engine coolant opening being blocked, the engine coolant warning light flashes and output control is applied simultaneously to lower heat generation.

•  If the engine coolant temperature exceeds 122 degrees C, the throttle valve opening is decreased and engine output is restricted according to the engine coolant temperature. At the same time, a DTC is stored. Engine coolant temperature warning light (red) flashes/is illuminated. Engine output restriction is canceled if the engine coolant temperature decreases below 117 degrees C.

•  If there is a claim from a user concerning drive performance deterioration because of the temporary output restriction, explain the contents of the repair order form and give the user appropriate advice.

•  After the engine speed restriction is completed a DTC is recorded in the PCM as a past record, and it is automatically cleared after 40 normal drive cycles have been completed.
