Compressor Protection Control At Pressure Malfunction
WARNING: This page is about a different car, the 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
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 A/C relay OFF and stops the compressor.
- 3.12 MPa (31.82 kg/cm2 , 452.4 psi) or more (When the engine speed is less than 1,500 RPM)
- 2.74 MPa (27.95 kg/cm2 , 397.3 psi) or more (When the engine speed is 1,500 RPM or more)
- 0.14 MPa (1.43 kg/cm2 , 20.3 psi) or less
