+24 VDC is measured between P/J720-1 and -5 on the IIT/IPS
PWB.
Y
N
Remove the IIT Top Cover (
REP 6.3
).
+24 VDC is measured between J702-1 and

Y
N
Approxi3.7 VDC is measured between J705-3 on the IIT LVPS and
GND.
Y
N
Go to
Flag 7
. Check the wire for an open circuit. If the wire is good,
replace the ESS PWB (
PL 13.1
).
+5 VDC is measured between J705-4 and GND.
Y
N
Go to
Flag 1
. Check the wire for an open circuit. If the wire is good,
replace the ESS PWB (
PL 13.1
).
AC Line Voltage is measured between P700/J2 on the IIT LVPS.
Y
N
Ensure that the AC Harness (
PL 18.4
) between the IOT and the IIT is con-
nected properly. If ok, go to
Flag 2
. Check the wires for an open circuit.
Go to
Flag 3
. Check the wires for a short circuit. If the wires are OK, replace the
IIT LVPS (
PL 18.4
).
Go to
Flag 3
. Check the wires for an open circuit.

Y
N
Replace the IIT/IPS PWB (
PL 18.3
).
+3.3 VDC is measured between J726-A6 and A8.
Y
N
Go to
Flag 5
. Check the wires for a short circuit. If the wires are OK, replace the IIT/
IPS PWB (
PL 18.3
).
+5 VDC is measured between J726-A10 and -A9.
Y
N
Go to
Flag 6
. Check the wires for a short circuit. If the wires are OK, replace the IIT/
IPS PWB (
PL 18.3
).
Go to
Flag 4
,
Flag 5
, and
Flag 6
. Check the wires for an open or short circuit. If the wires
are good, replace the UI Assembly (
