If refrigerant pressure on the high pressure side becomes high, the DTC will be set. It is necessary to
measure the voltage for a certain amount of time (approximately 10 minutes) because the DTC may be set
after the air conditioning operates for a while.
hen the outside air temperature is low (below -1.5°C (29.3°F)), the compressor stops due to operation of
the ambient temperature sensor and the evaporator temperature sensor to prevent the evaporator from
freezing. In this case, perform the inspection in a warm indoor environment.
If refrigerant pressure is not normal after replacing the cooler expansion valve with a new or known good
one, the condenser or pipes may be clogged due to dirt, dust or other foreign matter. In this case, clean or
replace the cooler condenser assembly or pipes.
