2. Stop engine.
3. Turn ignition switch OFF.
4. Check ground connection E15. Refer to Ground Inspection in
.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> Repair or replace ground connection.
2.
CHECK REFRIGERANT PRESSURE SENSOR POWER SUPPLY CIRCUIT
1. Disconnect refrigerant pressure sensor harness connector.
2. Turn ignition switch ON.
3. Check the voltage between refrigerant pressure sensor harness connector and ground.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> GO TO 3.
3.
DETECT MALFUNCTIONING PART
