009-684 ADC SHUTTER FAILURE

Description An operation failure of the ADC SHUTTER
BSD on : CH9.16 CH9.31D
Procedure
Run the DC330 [009-078].
Was the ADC SHUTTER SOLENOID actuated?
Y N
Is +24 VDC measured between the I/F PWB J536-A7 (+)
and GND (-)?
Y N
Check the +24 VDC circuit to the I/F PWB J536-A7
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)
Run the DC330 [009-078].
Is 0 VDC measured between the I/F PWB J536-A8 (+) and
GND (-)?
Y N
Check the wire between the I/F PWB J536-A8 and
the ADC SENSOR UNIT J602-3 for an open circuit
and poor contact. If no problems are found, replace
the I/F PWB (PL9.1) and the MCU PWB (PL13.1) in
sequence.
Run the DC330 [009-079].
Has the voltage between the I/F PWB J536-A6 (+) and
GND (-) changed to 0 VDC momentarily?
Y N
Check the wire between the I/F PWB J536-A6 and
the ADC SENSOR UNIT J602-1 for an open circuit
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 J536 and the ADC
SENSOR UNIT J602 for an open circuit and poor contact.
If no problems are found, replace the ADC SENSOR
ASSY. (PL1.3)
After checking that no failures are detected during normal
operation, end the Diag.

009-910 DRUM TYPE MISS MATCH (K)

Description DRUM Type Mismatch
BSD on : CH9.4 CH9.31B
Procedure
Run DC330 [009-154].
Is H displayed?
Y N
Check installation status of the DRUM.
Check the wire between the DRUM (K) J153 and the MCU
PWB J405 for an open circuit and poor contact. If no problems
are found, replace the DRUM (K). (PL4.1)
Replace the MCU PWB. (PL13.1)

009-911 DRUM TYPE MISS MATCH (C)

Description DRUM Type Mismatch
BSD on : CH9.4 CH9.31B
Procedure
Run DC330 [009-153].
Is H displayed?
Y N
Check installation status of the DRUM.
