Are you close to any MC dealer? Call and ask if they have a diagnostic computer & someone who knows how to use it.

Hey Jim,

The OBD II and the CAN connectors are not the same and you cannot read codes from MEFI 5 ECMs without a CAN.

Normal automotive OBD II



CAN connector.



Left to right:

Perfect pass adapter for CAN connector(used to hook to mefi 5 ecms when the boat has a PP), MEFI 1-4 diacom DLC connector, CAN adapter, Diacom cable.



OP, You'll need a DIACOM system to pull codes on your boat.
