GENERAL
Engine problems are not necessarily related to the
engine management system.
It is important to ensure that the mechanical in-
tegrity of the engine and drive system are present:
– good transmission system operation
– good engine compression and properly operat-
ing mechanical components, no leaks etc.
– fuel pump connection and fuel lines without
leaks.
Check the chart in TROUBLESHOOTING section
to have an overview of problems and suggested
solutions.
When replacing a component, always check its
operation after installation.
FUEL SYSTEM
WARNING
The fuel system of a fuel injection system
holds much more pressure than that of a car-
bureted snowmobile. Prior to disconnecting
a hose or to removing a component from
the fuel system, follow the recommenda-
tion described here. Pay attention that some
hoses may have more than one clamp at their
ends. Ensure to reinstall the same quantity
of clamps at assembly.
– UsetheVCK(VehicleCommunicationKit)
(P/N 529 035 981) to release the fuel pressure
in the system. Look in the Activation section
of the software B.U.D.S. (ensure to use the
latest version available on BOSSWeb).
