(+) and GND (-)?
Y
N
Check the wire between the I/F PWB J534-B11
and the MAIN MOTOR J203-5 for an open cir-
cuit and poor contact. If no problems are found,
replace the I/F PWB (PL9.1) and the MCU PWB
(PL13.1) in sequence.
Check the wire between the I/F PWB J534-B11 and
the MAIN MOTOR J203-5 for an open circuit and
poor contact.
Run
DC330
[004-004].
Is 0 VDC measured between the MAIN MOTOR J203-6
(+) and GND (-)?
Y
