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. If you are unable to determine the cause of an illuminated MIL, please see your POLARIS dealer. Flashing MIL (Turbo) The MIL will flash if an error with the turbo boost regulation system is detected. NOTICE: 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. 1. Verify that all electrical connections are secure. 2. Check battery voltage on the gauge, and install a new battery if voltage is low (see page 52). 3. Verify that engine temperature is within the recommended operating range. See the Turbo Boost chart on page 38. 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 immediately. NOTICE: Serious engine damage may occur if the wastegate reference line is removed or modified. DO NOT remove or modify the wastegate reference line. 37
