SHORT CIRCUIT TO BATTERY ERROR ON POWER STAGE FOR THE COMPRESSOR 

     

    

 

AC COMPRESSOR POWER STAGE

 

    

The AC Compressor is controlled by the EMS ECU under the feedback of the temperature sensing 

unit in the HVAC system and pressure sensors measuring the pressure of the refrigerant flow in 

the air conditioning circuit. The ECU monitors the status of the Power Stage (Actuator) of the 

Compressor Clutch for monitoring hardware errors such as short circuit to battery, Short circuit 

to ground and Open load

.
