Malfunction How to check
[2] Inspection at the time of 20A fuse blow
Please check the following points if the 20A fuse blows.
Because there are many high-voltage parts in the set main body, please disconnect the power plug when conducting an inspection other than confirm-
ing the operation.
Regarding harness, please also check caulking fault and contact fault.
（Normal operation）
When the door is closed,
is there electricity conducted between
motor SW terminals?
NO
NO
Checking completed
YES
YES
(Fuse blown)
Check Noise Filter
Between N and H = 275 - 415Ω
Between terminal N and LOAD = Short Circuit
Between terminal H and LOAD = Short Circuit
Fuse = Short Circuit
If fuse is open, replace fuse
