Test 1 : Check Open or Short-circuit and Diode (D1)
Test 2 : Check the Output DC voltage (between P and N)

P
Check the Output DC voltage (between P and N) of compressor stopping and operating.
If it is abnormal,replace ACTIVE FILTER MODULE
Remove connector, check the open or short-circuit and the diode in the module
>> If the output voltage of compressor operating is less than the output voltage of compressor stopping,
Active Filter Module is detective. >> Replace Active Filter Module
Check the open or short-circuit
