U3: Harness Short to Screen

With EM010, EM011, PI006 and PI042 disconnected, measure the insulation resistance between EM011/014 and EM010/020
Repeat for EM011/014 and EM010/02121
Repeat for EM011/014 and EM011/008
Repeat for EM011/014 and EM011/012
Repeat for EM011/014 and EM011/013
Repeat for EM011/014 and EM011/015
Repeat for EM011/014 and EM011/016

- All resistances > 10 M ohms?
Yes
GO to U4 U4: Check Harness Core to Core Insulation
No
Inspect EM010 and EM011 for corrosion, bent/pushed back pins or locate harness/connector PI001. Repair as necessary and test the system for normal operation.
