FEATURES
Engine Management System
Malfunction Indicator Lamp (MIL)
Illuminated MIL
The MIL (Check Engine Indicator) will illuminate when a problem with
engine management system components is detected.
1. Turn the engine off and restart it. If the light goes off, continued
operation is permissible.
2. If the light illuminates again, determine whether engine RPM or
vehicle speed is limited, then check the charts on page 38 to identify
the cause.
NOTE: If you are unable to determine the cause of an illuminated MIL, please
see your Polaris dealer.
Flashing MIL (FST)
The MIL will flash if an error with the turbo boost regulation system is
detected.
1. Verify that all electrical connections are secure.
2. Check battery voltage on the gauge, and install a new battery if volt-
age is low (see page 52).
3. Verify that engine temperature is within the recommended operating
range. See the Turbo Boost chart on page 39.
A flashing MIL may also be caused by damaged or disconnected hoses
between the turbocharger and wastegate solenoid pulse valve (located
on the engine side of the airbox) or between the wastegate actuator
(located under the turbocharger) and wastegate solenoid pulse valve. If
the hose has no damage and is not disconnected, see your dealer imme-
diately.
CAUTION
If you are unable to determine and correct the cause of a flashing MIL or high
temperature indicator, serious engine damage may occur with continued
operation. See your Polaris dealer.
CAUTION
Serious engine damage may occur if the wastegate reference line is
removed or modified. DO NOT remove or modify the wastegate reference
line.
