On-Board Diagnostics – Marine (OBD-M)
All Ilmor High-Performance Marine engines are equipped with marine on-
board diagnostics to comply with the 2009 California-mandated OBD-M
specification. The Malfunction Indicator Lamp (MIL) or a Check Engine
warning will appear on the dash when emission system problems occur on
the boat.
If the MIL is set due to an emissions-related fault, a Diagnostic Trouble
Code (DTC) will register. The MIL functions to notify the operator that a
problem has occurred so that the owner/operator can arrange for service
as soon as possible. DTCs are stored in the engine control unit memory
and can be retrieved with a diagnostic scan tool or through Diacom PC
Software.
This information about system malfunction assists the service technician
in quickly diagnosing system issues. When the MIL lights, the owner /
operator should contact an authorized Ilmor service center to arrange a
diagnostic scan at the earliest possible opportunity.
The diagnostic scan tool will be connected to the Data Link Connector
(DLC), a flat 6-pin connector. The connector is located adjacent to the port
side fuel rail. Note that the protective DLC cover must be removed prior to
connecting the scan tool.
