Trouble phenomenon A journey of 60,000 km of 2003 wide this Fit car, connected to air-conditioning switch, the wind out of the outlet, but the air conditioning is not cooling. Fault diagnosis The car uses a manual air conditioning system, but canceled the traditional model of air conditioning amplifier, the engine control module (ECM) directly under the integrated control, ECM receives from the evaporator temperature sensor, high and low pressure switch and A / C switch and other signals , And then integrated the engine temperature and load conditions were controlled air conditioner compressor, radiator fan and condenser fan work, from
