When high-pressure side value that is detected by refrigerant pressure sensor is as per the following state, ECM requests IPDM E/R to turn air conditioner relay OFF and stops the compressor.
- 3.12 MPa (31.20 bar, 31.8 kg/cm2 , 452 psi) or more (When the engine speed is less than 1, 500 rpm)
- 2.74 MPa (27.40 bar, 27.9 kg/cm2 , 397 psi) or more (When the engine speed is 1, 500 rpm or more)
