Troubleshooting for Each Error Code
E 8 0
Indication
1. Split cycle outlet temperature sensor connector (2P2) disconnected or contact failure
Probable
2. Split cycle outlet temperature sensor failure
Cause
3. Control PCB (CS1-PCB) failed
1. Check if the connector (2P2) on CS1-PCB is disconnected or loose.
2. Check the resistance value of the split cycle outlet temperature sensor, and check if the
Check
sensor and wiring is open or shorted.
[Method of checking]
Refer to "Method of Checking Sensor Characteristics" in the section "Failure Diagnosis".
1. Correct the attachment of the connector (2P2) on the CS1-PCB.
Corrective
2. Replace the split cycle outlet temperature sensor.
Action
3. Replace the control PCB (the CS1-PCB).
E 8 1
Indication
1. Intermediate pressure sensor connector (3P2) or pressure sensor side connector
disconnected or contact failure
Probable
2. Intermediate pressure sensor failure
Cause
3. Control PCB (CS1-PCB) failed
1. Check if the connector (3P2) on CS1-PCB, or pressure sensor side connector is
disconnected or loose.
2. Check the output voltage of intermediate pressure sensor and check if the sensor and
Check
wire is open or shorted.
[Method of checking]
Refer to "Method of Checking Sensor Characteristics" in the section "Failure Diagnosis".
1. Correct the attachment of the connector (3P2) on the CS1-PCB or pressure sensor side
connector.
Corrective
2. Replace the intermediate pressure sensor.
Action
3. Replace the control PCB (the CS1-PCB).
