A5: Check Harness Continuity

Disconnect P1034 &, measure the resistance, in turn between;
EM012/001 & PI034/004
EM012/002 & PI034/001
EM012/003 & PI034/006
EM012/004 & PI034/003

Is the resistance < 0.5 ohms?

Yes
Go to A6

No
Inspect EM012 & PI034 for bent/pushed back pins or locate & repair the appropriate harness/connector PI001/008, PI001/009, PI001/010 or PI001/007
