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 mes-
sages through the information center
and/or audible signals through a beep-
er to inform you of a particular con-
dition. Refer to the INFORMATION
CENTER GAUGE for the displayed
messages and the TROUBLESHOOT-
ING 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
advanced system.

Engine Overheating

CAUTION: If the monitoring beeper
continuously sounds, stop engine
as soon as possible.
Check coolant level. Refer to LIQ-
UIDS. If engine still overheats, contin-
ue the following procedure.
Perform JET PUMP WATER INTAKE
AND IMPELLER CLEANING proce-
dure described in this section.
When back to shore, flush exhaust
cooling system,
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
correct the situation, do not run the
engine further. Refer to an authorized
Sea-Doo dealer for servicing.
CAUTION: Running engine with
low oil pressure may severely dam-
age the engine.
