except a diagnostic trouble code
(DTC) code will flash on the LCD
and a check engine indicater will
be displayed whenever an elec-
tronic fuel injection malfunction
or electronic power steering mal-
function is detected. After 30 sec-
onds, the LCD will return to
normal; however, the DTC and
check engine indicater will con-
tinue to be displayed until the mal-
function is corrected.
NOTE: Take the ATV to an autho-
rized Arctic Cat ATV dealer to have
the EFI error corrected and to have
the ECM reset as soon as possible.
Electric Fuel Pump
An electric fuel pump is incorporated in
the gas tank to deliver gasoline to the fuel
injector. The fuel pump is activated when
the ignition switch is in the ON position.

pump functions will be interrupted by
the Tilt Sensor if the ATV tips over
past 60°-70°. Righting the ATV will
reactivate the ignition and fuel pump.

the seat to deliver gasoline to the carbure-
tor. The fuel pump operates when the
engine is turning.

NOTE: The heat shield can be
removed after seat removal by
pulling outward at the top to disen-
gage the mounting lugs from the

then install the heat shield, front
seat, and rear seat making sure the
