Check Exit Sensor Harness continuity.
1. Disconnect P/J8321 and P/J8312.
2. Check for continuity at the following:
P/J8321-3 <=> J8312B-1
P/J8321-2 <=> J8312B-2
P/J8321-1 <=> J8312B-3
Are these conductive?
Go to Step 14. Repair the Upper

J8312A-1 <=> P/J8302A-9
Are these conductive?
Go to Step 15. Repair the Main
