Exit Comm Failure Troubleshooting Procedure
Step Actions and Questions
1 Check the Exit PWB connection.
Are P/J431 and P/J421 connected?
2 Check continuity between the Exit PWB
and the 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?
3 Check the connection between the Exit
PWB and the LVPS.
Are P/J430 and P/J526 connected?
4 Check continuity between the Exit PWB
and the LVPS.
1. Disconnect P/J430 and P/J526.
2. Check for continuity at the following:
P/J430-3 <=> P/J526-6
P/J430-4 <=> P/J526-5
P/J430-1 <=> P/J526-8
P/J430-2 <=> P/J526-7
Are these conductive?
5 Check for +24 V to the Exit PWB.
Is there +24 V across P/J430-1 (+) <=>
ground?
