Check code Operation cause
1. Connector misconnection of Pd/Ps sensors
[Ab]
2. Pd/Ps sensor error
Pressure sensor misconnection
3. Compressor inverse operation, compressor error
Is the pipe connection
position of Pd sensor/Ps
sensor correct?
Are the output voltage
characteristics of Pd sensor/Ps
sensor normal?
Check connection.
Pd sensor: CN501
Ps sensor: CN500
Check the interface board.
Check compressor.
Sensor error
No
Yes
No
Yes
Are the pressure
characteristics normal when
compressor is operating?
