6-345 Pre IPS EEPROM Failure RAP
A Failure was detected when writing to the NVM and a communication failure with the
EEPROM when writing into the Pre IPS PWB NVM.
Initial Actions
• Refer to BSD 3.3 PWB Communications (DADF) in this procedure:
• Ensure that P/J551 on t
he DADF Control PWB is firmly seated.
Procedure
PO/PO the machine. Fault Code is still declared.
YN
Inspect the PRE IPS PWB the MEM SYS PWB, the POST IPS PWB for loose connec-
tions or any obvious electrical/mechanical
cause f
or malfunction.
Perform the following:
• Replace the PRE IPS PWB (PL 3.5).
• Replace the MEM SYS PWB (PL 3.
5).
• Replace the Post IPS PWB (PL 3.
5).
6-355 IPS Fan Fail RAP
The IIT Driver PWB detected a control error caused by an IPS Fan failure. This error is not
detected during document scan.
Initial Actions
Refer to BSD 6.1 and BSD 6.7 in the following procedure.
Procedure
Enter dC330 006-013 Cooling Fan High Speed. Press Start. The IPS Fan rotates.
YN
Press S
top. Enter d
C330 006-003 Cooling Fan Low Speed. Press Start. The IPS Fan
rotates.
YN
+3.5VDC is measured between P/
J524-4
and GND on the IIT Driver PWB.
YN
Go to F
lag 5 on t
he BSD 6.1 and check the wire for an open or short circuit. If
the wire is OK, replace the Pre IPS PWB (PL 3.5).
+24VDC is pulsed between P/J523
-2 and P/J523-4 on the IIT Drive PWB.
YN
Replace the IIT Driver PWB (PL 3.
2).
Pr
ess Stop. Sele
ct [06013]. Press Start. +5VDC is measured between P/J524-3
and GND on the IIT Driver PWB.
YN
Go to F
lag 6 on t
he BSD 6.1 and check the wire for an open or short circuit. If
the wire is OK, replace the Pre IPS PWB (PL 3.5).
+24VDC is measure between P/J52
3-1 and P/J523-4 on the IIT Driver PWB.
YN
Replace the IIT Driver PWB (PL 3.
2).
G
o to Flag 2 on BSD 6.1 and check the wires for an open or short circuit. If the wires
are O
K, replace the IPS Fan (PL 3.2).
Press Stop. Sele
ct [06-013]. Press Start. +5VDC is measured between P/J524-3 and
GND on the IIT Driver PWB.
YN
Go to F
lag 6 on the B
SD 6.1 and check the wire for an open or short circuit. If the
wire is OK, replace the IPS PWB (PL 3.5).
+24VDC is measured between P/J523
-1 and P/J523-4 on the IIT Driver PWB.
YN
Replace the IIT Driver PWB (PL 3.
2).
Go
to Flag 2 on BSD 6.
1 and check the wires for an open or short circuit. If the wires are
OK, replace the IPS Fan (PL 3.2).
+5VDC is measured between P/J515
-16 and GND on the Pre IPS PWB.
