Compressor Protection Control At Pressure Malfunction

When high-pressure side value that is detected by refrigerant pressure sensor is as per one of the following states, ECM requests IPDM E/R to turn A/C relay OFF and stops the A/C compressor.

• 3.12 MPa (31.82 kg/cm ² , 452.4 psi) or more (when the engine speed is less than 1, 500 RPM)
• 2.74 MPa (27.95 kg/cm ² , 397.3 psi) or more (when the engine speed is 1, 500 RPM or more)
• 0.14 MPa (1.43 kg/cm ² , 20.3 psi) or less
