Vehicle arrived as non runner, global scan of vehicle shows no communication to engine ecu & fault in the Passenger compartment module as Engine ecu no reply. Obtained accurate engine wiring diagram from Autologic and found that the earth control from pin A2 on engine ecu brown plug to the multifunction relay pin 10 was missing.

After making engine harness accessible found wire corroded at the lower part of the plastic
trunking in main engine harness.Regards Gary
