Check the Chute Assembly Harness:
1. Disconnect P/J24 from the HVPS/
Engine Logic Board.
2. Disconnect P/J245.
3. Test the following for continuity:
■ J24-9 <=> J245-10
■ J24-10 <=> J245-9
■ J24-11 <=> J245-8
Is each conductor continuous?
Go to step 5. Replace the

Check the HVPS/Engine Logic Board:
1. Disconnect P/J11 from the HVPS/
Engine Logic Board.
2. Test P/J11-16 <=> P/J24-9 for continuity.
