With connectors EM012, EM013, EM027, EM029, PI019, PI020, PI022 & PI025 disconnected, measure the resistance between EM029/008 & EM029/009

Is the resistance > 10M Ohms?

Yes
Replace fuse F18 & reconnect all connectors
Go to A18

No
Inspect connectors EM029, PI001, PI019, PI020, PI022 & PI025 for bent/pushed back pins or locate & repair the harness. Test the system for normal operation
