Exit Offset Error (OCT Position Sensor) Troubleshooting Procedure (Continued)
Step Actions and Questions
4
Check for +5 V to the OCT Position Sensor.
Is there +5 V across P/J434-1 (Exit 2) or
P/J432-1 (Exit 1) (+) <=> ground?
5 Check the connection between the Exit
PWB and the Engine Logic Board.
Are P/J431 and P/J421 connected?
6 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?
7 Check the connection between the Exit
PWB and the LVPS.
Are P/J430 and P/J526 connected?
8 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?
9
Check for +24 V to the Exit PWB.
Is there +24 V across P/J430-1 (+) <=>
ground?
10 Test the Offset Motor.
Run the Service Diagnostics Offset Output
Motor tests for the appropriate Exit.
Does the Offset Motor operate
properly?
11 Check the affected Offset Motor
connection. Exit 1 P/J432 <=> J206 or Exit
2 P/J433 <=> J207.
Is the motor connected?
