SPECIAL PROCEDURES

Monitoring System

To assist you when using the water-
craft, a system monitors the electronic
components of the EMS (engine man-
agement system) and other compo-
nents of the electrical system. When a
fault occurs, it sends visual messages
through the information center and/or
audible signals through a beeper to in-
form you of a particular condition. Re-
fer to the INFORMATION CENTER for
the displayed messages and the TROU-
BLESHOOTING section for the beeper
coded signals chart.
When minor faults occur, the fault and
message/beeper will disappear auto-
matically if the condition does not exist
anymore.
Releasing throttle and letting the en-
gine returning at idle speed may allow
normal operation to come back. If it
does not work, try removing and rein-
stalling the safety lanyard on its post.
The electronic system will react differ-
ently depending on the fault type. In
severe failure, the engine might not be
allowed to be started. In other cases,
the engine will operate in limp home
mode. See below.
When a fault occurs, see an authorized
Sea-Doo dealer as soon as possible for
inspection.
Limp Home Modes
Besides the signals as seen above, the
EMS may automatically set default pa-
rameters to ensure the adequate oper-
ation of the watercraft if an electronic
component is not operating properly.
Depending on the severity of the mal-
function, the watercraft speed may be
reduced and not allowed to reach its
top speed as usual.
In this mode, it may be necessary to
depress the throttle quite slowly to al-
low engine RPM to increase and oper-
ate the watercraft to go back home.
These performance-reduced modes
allow the rider to go back home which
would not be possible without this ad-
vanced system.

Engine Overheating

CAUTION: If the monitoring beeper
continuously sounds, stop engine as
soon as possible.
Check coolant level. Refer to LIQUIDS.
If engine still overheats, continue the
following procedure.
Perform Jet Pump Water Intake and
Impeller Cleaning procedure described
in this section.
When back to shore, flush exhaust cool-
ing system, refer to POST-OPERATION
CARE.
If engine still overheats, refer to an au-
thorized Sea-Doo dealer for servicing.

Engine Low Oil Pressure

CAUTION: If the monitoring beeper
continuously sounds, stop engine as
soon as possible.
Turn off engine as soon as possible.
Check oil level and refill.
Restart the engine. If this does not cor-
rect the situation, do not run the en-
gine further. Refer to an authorized
Sea-Doo dealer for servicing
CAUTION: Running engine with low
oil pressure may severely damage
the engine.
