[Diagnosis Point]
Check the indoor /outdoor cable connection (in order). If the cable wiring is not abnormal, measure the voltage of the outdoor
unit terminals and diagnose the defective location.
(Refer to the after mentioned [Serial Signal Diagnosis] for the voltage measuring method and diagnosis method.)
