Magnet Clutch Circuit
Magnet Clutch CircuitSYMPTOM: Magnet clutch does not engage.
Step 1-5:
INSPECTION FLOW
SYSTEM DESCRIPTION
The front air control controls A/C compressor operation based on intake temperature and a signal from ECM. The ECM may not allow A/C compressor operation if refrigerant pressure sensor value is too high.
Low Temperature Protection Control
The front air control will turn the A/C compressor ON or OFF as determined by a signal detected by the intake sensor.
When intake air temperature is higher than 3.5 °C (38.3 °F), the A/C compressor turns ON. The A/C compressor turns OFF when intake air temperature is lower than 2.5 °C (36.5 °F).
