FIP-1.76 077-215: IOT Duplexer Failure
Step Check
Remedy
Yes No
Possible causative parts:
HARNESS ASSY OPTION MG AIO (PL3.1.20)
PWBA MCU (PL8.3.6)
HARNESS ASSY DUP STD MG AIO (PL11.1.14)
FEEDER ASSY DUP AIO STD (PL11.1.1)
1
Checking the Option Duplex for installation.
Is the Option Duplex installed correctly?
Go to step 3.
Reseat the Option
Duplex, then go to
step 2.
2
Does the error still occur when the power is turned OFF and
ON?
Go to step 3. End of work.
3
Checking the connectors for connection.
Check the connections between the PWBA DUP and PWBA
MCU.
Are P/J27, P/J272 and P/J 601 connected surely?
Go to step 5.
Reconnect the
connector(s) P/
J27, P/J272 and/
or P/J 601 surely,
then go to step 4.
4
Does the error still occur when the power is turned OFF and
ON?
Go to step 5. End of work
5
Checking theHARNESS ASSY DUP STD MG AIO for
continuity.
Disconnect P/J601 from the PWBA DUP.
Disconnect P/J271 from the HARNESS ASSY OPTION MG
AIO.
Is each cable of P/J601 <=> P/J271 continuous?
Go to step 6.
Replace the
HARNESS ASSY
DUP STD MG
AIO.
6
Checking the HARNESS ASSY OPTION MG AIO for
continuity.
Disconnect P/J27 from the PWBA MCU.
Disconnect P/J 271 from the HARNESS ASSY DUP.
Is each cable of P/J27<=> P/J271 continuous?
Go to step 7.
Replace the
HARNESS ASSY
OPTION MG AIO.
7
Checking after replacing the FEEDER ASSY DUP AIO STD.
Replace the FEEDER ASSY DUP AIO STD. (Refer to
REP10.1.)
Does the error still occur when the power is turned OFF and
ON?
Replace the KIT
PWBA MCU.
(Refer to
REP8.10.)
End of work.
