Control By ECM
Compressor Protection Control at Pressure Malfunction
The high-pressure side value that is detected by refrigerant pressure sensor is as per the following state, ECM requests IPDM E/R to turn A/C relay OFF and stop the 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)
- 0.12 MPa (1.22 kg/cm 2 , 17.4 psi) or less
Air Conditioning Cut Control
When the engine condition is high load, ECM makes the A/C relay to OFF, and stops the compressor.
