•  A triple pressure type has been adopted.

•  Consists of the low/high-pressure switch that protects the refrigerant cycle by cutting the A/C signal when pressure in the refrigerant cycle is abnormally high or low, and the medium-pressure switch that outputs an idling increase signal according to the A/C compressor operation load.

•  When the refrigerant pressure reaches approx. 1.44 MPa {14.7 kgf·cm², 209 psi} or more, the contact turns on, and a cooling fan control signal is sent to the PCM.
