Go to Step 3.
3
Check the Stack Full Sensor connections.
For Exit 1:
Are P/J118, P/J613 and P/J432
connected?
For Exit 2:
Are P/J113, P/J606B and P/J434
connected?
Go to Step 4. Connect the
sensor.
4
Check continuity between the Stack Full
Sensor and the Exit PWB.
For Exit 1:
Is there continuity on each wire
between P/J118 <=> P/J432?
For Exit 2:
Is there continuity on each wire
between P/J113 <=> P/J434?
Go to Step 5. Repair the wiring.
5
Check for +5 V to the Stack Full Sensor.
For Exit 1:
Is there +5 V across P/J118-3 (+) <=>
ground?
For Exit 2:
Is there +5 V across P/J113-3 (+) <=>
ground?
Replace the Full
Stack Sensor.
Go to Step 6.
6
Check the Exit PWB connections.
Are P/J421 and P/J431 connected?
Go to Step 7. Connect P/J421

7
Check continuity between the Exit PWB
and Engine Logic Board.
1. Disconnect P/J431 and P/J421.
2. Check for continuity at the following:
P/J431-1 <=> P/J421-8
P/J431-2 <=> P/J421-7
P/J431-3 <=> P/J421-6
P/J431-4 <=> P/J421-5
P/J431-5 <=> P/J421-4
P/J431-6 <=> P/J421-3
P/J431-7 <=> P/J421-2
P/J431-8 <=> P/J421-1
Are these conductive?
Go to Step 8. Repair the wiring.
8
Check for +5 V to the Exit PWB.
Is there +5 V across P/J421-3 (+) <=>
ground?
Replace the Exit
PWB (
page 8-88).
Replace the
Engine Logic
Board
(
