3-330 2nd DDI IISS Communication Failure RAP, 3-
Status Indicator RAPs
Reissue
3-330 2nd DDI IISS Communication Failure RAP
• 3-330 Fault Code indicates that a communication failure between the IOT PWB and the
DDI IISS was detected.
Initial Actions
Refer to BSD 16.1, Printer IDFE, in this procedure.
Procedure
Perform the following:
• PO/PO the machine
• Go to BSD 16.1 (Figu
re 1) and check the communications cables.
• Reset the IOT CPU connectors and reseat the IOT NVM PWB.
• Reload IDFE System Software
• Replace the IOT CPU PWB (PL 9.
2)
• Replace the IDFE (PL 19.1
)
3-333 Foreign Interface RAP
This Fault Code indicates that a communications failure was detected between the Foreign
Interface PWB and the IOT CPU PWB.
Initial Actions
• Check the connection between the Foreign Interface PWB and the Foreign Accessory (P/
J 940).
• If you were sent to this RAP from Call Flow for a nonrecognized Foreign Device, go to
Flag 1
on BSD 3.6 and check for an open circuit.
• Use BSD 3.6, Foreign Interface Accessory, and BSD 3.12, Monitoring, for this procedure.
Procedure
PO/PO the machine. Fault Code 3-333 is still present.
YN
If intermittent performance is suspected, reseat P/
J406 at
the IOT CPU PWB, P/J45 at
the Distribution PWB, and P/J 941at the FI PWB.
There is +24 VDC from J 941, pin 5 to pin 7.
YN
Go to F
lag 2 on BSD 3.6. Check for an open circuit. If the wires are OK, go to the 24 VDC
wirenets t
o troubleshoot.
There is +5 VDC from J 941, pin 10 to pin 8.
YN
Go to F
lag 3 on BSD 3.6. Check for an open circuit. If the wires are OK, go to the +5 VDC
wirenets t
o troubleshoot.
Perform the following:
•Go to Flag 4 and F
lag 5 on BSD 3.6, and check for an open/short circuit.
• Replace the Foreign Interface PWB (PL 9.4).
• R
eplace the IOT CPU PWB (PL 9.
2).
