• The voltage of the Thermistor remains low for a prede-
termined period of time after a warm-up cycle is
started.
• The temperature detected by the Thermistor remains
lower than a reference value for a 9 second period of
time beginning 5 seconds after the start of the warm-
up cycle (where the temperature detected by the Ther-
mistor is 80 °C or less).
• The temperature detected by the Thermistor does not
increase for a 3 second or longer period between the
time beginning after the lapse of a predetermined
