Clearance Method
1. Check the connections between:
a) ECN8 of IOD2 and the solenoid
b) ECN2 of IOD2 and DCN9 of
c) DCN1 of IOD1 and 11CN of MCTL P.W.B.
3. If voltage between ECN8-4 and ECN2-8 of
IOD2 is trailing edge then replace the
transfer solenoid.
4. If voltage between ECN2-3 and 12 of IOD2
is rising edge then replace the IOD2
5. If voltage between ECN2-31 and 1 of IOD1
is rising edge then replace the IOD1
6. Replace MCTL PWB

1. Check the connections between:
a) ECN10 of IOD2 and the solenoid
b) ECN2 of IOD2 and DCN9 of
c) ECN1 of IOD1 and 11CN of MCTL P.W.B.
3. If voltage between ECN10-4 and 8 of
IOD2 is trailing edge then replace the
c leaning brush solenoid.
4. If voltage between ECN2-2 and 12 of IOD2
is rising edge then replace the IOD2
