PWBA DUP
PWBA MCU
Step
Check
Yes
No
1
Check the connection of the DUP JAM
SENSOR
Check the connection state between DUP JAM
SENSOR and PWBA DUP.
Are P/J430 and P/J4301 connected correctly?
Go to Step [2].
Reconnect P/J430
and P/J4301
correctly.
2
Check the continuity of the HARNESS ASSY
DUP SNR
Is the continuity between P/J430 <=> P/J4301
normal?
Go to Step [3].
Replace the
HARNESS
ASSY DUP SNR.
3
Check the power voltage supply to DUP JAM
SENSOR
Measure the voltage between PWBA DUP
ground <=> P/J430-1PIN.
Is the power voltage (approx. +3.3 V) output?
Go to Step [4].
Go to Step [5].
4
Check the operation of the DUP JAM
SENSOR
Measure the voltage between PWBA DUP
ground <=> P/J430-3PIN.
Does the voltage change when the DUP JAM
SENSOR is shielded from light?
Go to Step [5].
Replace the DUP
JAM SENSOR.
5
Check the connection between PWBA DUP
and PWBA MCU
Check the connection state between PWBA
DUP and PWBA MCU.
Are P/J428, P/J2720, P/J272, and P/J27
connected correctly?
Go to Step [6].
Reconnect
P/J428, P/J2720,
P/J272, and P/J27
correctly.
Step
Check
Yes
No
6
Check the continuity of the HARNESS ASSY
DUP UNIT
Is the continuity between P/J428 <=> P/J2720
normal?
Go to Step [7].
Replace the
HARNESS
ASSY DUP
UNIT.
7
Check the continuity of the HARNESS ASSY
FRONT COVER
Is the continuity between P/J2720 <=> P/J272
normal?
Go to Step [8].
Replace the
HARNESS
ASSY FRONT
COVER.
8
Check the continuity of the HARNESS ASSY
R SIDE
Is the continuity between P/J27 <=> P/J272
normal?
Go to Step [9].
Replace the
HARNESS
ASSY R SIDE.
9
Check the power voltage supply to PWBA
DUP
1. Close the interlock switch (HARNESS
ASSY INTERLOCK) before performing
the following work.
2. Measure the voltage between PWBA
MCU ground <=> P/J27-A17, A18PIN.
Is the power voltage (approx. +24 V) output?
Replace the
PWBA DUP.
Replace the
PWBA MCU.
