1.CHECK MAGNET CLUTCH OPERATION
Check magnet clutch. Refer to HAC-175, "Component Function Check".
Does it operate normally? YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK REFRIGERANT PRESSURE SENSOR
Check refrigerant pressure sensor. Refer to the following.
• HR16DE: Refer to EC-790, "Component Function Check".
• MR16DDT: Refer to EC-423, "Component Function Check".
• K9K: Refer to EC-960, "DTC Logic".
Is the inspection result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.CHECK A/C ON SIGNAL
Check A/C ON signal. Refer to HAC-166, "Component Function Check".
