TROUBLESHOOTING SUMMARY

ENGINE DOES NOT START

If the engine does not start, the following items
should be verified in this order:
– fuses
– ignition (spark)
– fuel pump
– check fault codes in the ECU memory.

FLOODED ENGINE FEATURE

If the engine does not start and it is flooded, pro-
ceed as follows:
Remove spark plug cables and connect them on
the grounding device.
Remove spark plugs and dry them using a rag.
Cover spark plug holes with a rag.
Depress and hold the throttle lever at full throttle
position.
Install the safety lanyard cap on the switch. Press
the start/stop button wait 2 seconds then crank
the engine for approximately 10 seconds.
NOTE: Proceeding in this order, no fuel is injected
and the accumulated fuel in the engine will be ex-
pelled.
Reinstall spark plugs and connect cables.
Start engine normally without applying the throt-
tle.

SPARK PLUG INSPECTION

Whenever replacing the spark plugs, always use
NGK BR8ES with the resistor feature. The spark
plug gap is set to 0.5 - 0.6 mm (.02 - .024 in).
To check for ignition, attach an inductive timing
light to the high tension lead while turning the en-
gine with the starter.
Reversed high tension cables will not allow the RFI
to run. Unlike other Sea-Doo models, the spark plugs
spark independently on each piston stroke. Re-
versed high tension cables will cause backfires.

ECU FAULT CODES

Fault codes in the ECU memory will identify poten-
tial problems with the RFI system. When checking
fault codes without engine in operation, the CPS
fault code will always appear. Also, the 04 FC fault
code will always appear.
Disconnecting the battery will erase the fault codes
in the ECU memory.
ENGINE STARTS BUT RUNS
POORLY
If the engine starts but runs poorly, the following
items should be verified in this order:
– Check spark plug condition.
– Check fault codes in the ECU memory.
– Check fuel pressure.
– Check TPS adjustment.
If some work has been performed on the unit,
make sure injector wire connectors were not
mixed. It is also possible that the RAVE solenoid
connector be mixed with one of the injector con-
nector. Refer to the wiring diagram for wire colors
and positions.
ENGINE STARTS BUT STALLS
AFTER APPROXIMATELY
30 SECONDS
The RPM signal (GREY wire) is short circuit to the
ground. Check wire condition. If the wire test
good, either the tachometer or Info Center is de-
fective.
ENGINE CANNOT REACH
MAXIMUM REVOLUTIONS
Check battery voltage. When voltage is too low,
the MPEM limits the engine revolutions.
Recharge or replace battery.
The RAVE system is not functioning properly. The
sliding valves do not open. Check pressure hoses
and check valve from crankcase to RAVE solenoid.
Check RAVE solenoid.
