“ENGINE FAULT” warning is triggered
from engine ECM data.
“CHECK TRANS” warning is triggered
from engine ECM data for overheating.
“HIGH SPEED WEDGE DOWN” is
shown when the boat is going above 25
MPH with the wedge down.
A warning for the “WEDGE MOVING”
only appears when the wedge is moving up
past the wake zones.
When the ignition is on, “AUTO BILGE
PUMP ON” will appear whenever the auto
bilge kicks in.

The “Engine Fault” alarm: Is activated by the ECM. The problem could be a
momentary out of parameter minor issue or the problem could be catastrophic . If the
“Engine Fault” alarm is activated, look at the gauges, oil P, temp and volts, and then shut
down the engine, Key off, then restart. If the problem was a minor momentary, out-of-
parameter fault, the fault should reset during the key cycle. If the problem is more
serious, the alarm will be reactivated after restart. If the alarm continues, you should
discontinue use until the problem is diagnosed and fixed.
On the 2010 Medallion Instrumentation system we have added OBD-M. OBD-M gives
you the ability to read the Fault Codes out of the ECM using the Multi Function LCD
Display. OBD-M is intended mainly for EFI Technicians to use, but would be beneficial
to have it available for our customers to use if the need arises. You can at least call your
dealer or Malibu and tell them what you see on the OBD-M screen.
To Enter the On-board-Diagnostics-Marine Tool , you will need to scroll the “UP” or
“DOWN” button to the “Service” screen. Once in the service screen, press “E (Enter).”
Then use the “UP” or “DOWN” arrows to highlight “Fault Codes”. At this point you will
need to pay close attention; you will now see two lists:
Active 1 or Inactive 1 . It is the 1 or
0 that is important here. If the fault is currently Active (a real serious problem), you will see
a 1 to the right of active. If the problem was a momentary out of parameter issue, you will
see a “0” next to Active and you will see a “1” to the right of Inactive. Inactive is much
better then Active. Inactive means the problem is gone or has fixed itself during the reset.
If the fault Code is Active, you will want to press the “E (Enter)” button with “Active 1”
highlighted in the screen. At this point you will read the Service Parameter Descriptions
and DTCs in its OBD-M format. Again, this tool is not intended for everyone, yet again,
it may tell you: “knock system no response” if you take a look and find the knock sensor
unplugged, you save the day and a trip to the dealer! If you are unable to resolve the
active code and the alarm continues and you have good oil pressure and engine
temperature, as soon as possible, take the boat back to the dealer.
