Is +24 VDC measured between the I/F PWB J550-5 (+) and
GND (-)?
Y
N
Check the +24 VDC circuit to the I/F PWB J550-5 by
referring to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1) (WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3) (WN4.3.16 +24 VDC-4)
Remove the IBT ASSY and run
DC330
[004-001].
Is the IBT STEERING MOTOR rotating?
Y
N
Check the wire between the I/F PWB J550 and the IBT
STEERING MOTOR J207 for an open circuit and poor
contact.
Is an open circuit or poor contact found?
Y
N
Replace the MCU MF PWB (PL13.1). If the problem
persists, replace the I/F PWB (PL9.1) and the IBT
STEERING MOTOR (PL1.3).
Repair the open circuit or poor contact.
Check the installation status of the IBT BELT. If no problems
are found, replace the MCU MF PWB.(PL13.1)
004-348 BELT EDGE SENSOR FAILURE
Description
The BELT EDGE SENSOR failure
BSD on : CH9.19 CH9.31A
Procedure
Is the Actuator of the EDGE SENSOR touching the BELT?
Y
N
Check the installation status of the Actuator.
Turn On the power.
Run
DC330
[004-014].
Is +3 VDC to +1 VDC measured between the I/F PWB J533-
A11 (+) and GND (-)?
Y
N
Is +5 VDC measured between the I/F PWB J533-A9 (+)
and J533-A10 (-)?
Y
N
If the voltage between the J533-A9 (+) and the J533-
A10 (-) is less than +5 VDC after closing the FRONT
door, replace the MCU MF PWB.(PL13.1)
Is +5 VDC measured between the I/F PWB J533-A11 (+)
and GND (-)?
Y
N
Is 0 VDC measured between the I/F PWB J533-A11
(+) and GND (-)?
Y
N
Check the wire between the I/F PWB J533 and the
IBT EDGE SENSOR J119 for an open circuit and
poor contact. If no problems are found, replace the
IBT EDGE SENSOR (PL5.4). If the problem
persists, replace the MCU MF PWB.(PL13.1)
Check the wire between the I/F PWB J533-A11 and
the IBT EDGE SENSOR J119-2 for an open circuit or
poor contact.
Replace the IBT EDGE SENSOR.(PL5.4)
Is +24 VDC measured between the I/F PWB J550-5 (+) and
GND (-)?
Y
N
Check the +24 VDC circuit to the I/F PWB J550-5 by
referring to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1) (WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3) (WN4.3.16 +24 VDC-4)
