B12: Check Harness Short to Core

With connectors EM015 and IJ003 to IJ010 disconnected and PI Main relay removed
Measure the insulation resistance, in turn, between pairs
EM015/004 and EM015/015
EM015/005 and EM015/016
EM015/006 and EM015/017
EM015/007 and EM015/018

- Is the resistance > 10 M ohms?
Yes
GO to B13 B13: End
No
Inspect harness/connectors PI001/037, 036, 034, 030, IJ001/002 and IJ001/005, IJ002/003 and IJ002/004. Repair as necessary and test the system for normal operation.
