    check eng. light 04 msx 150

    How do I go about finding out my problems on the ecm check engine light ?
    Do I have to find a dealer or is there another way to diagnose.

    I know this post is old, but answering for future reference. The MSX110/150 need dealer software (Polaris Digital Wrench) to diagnose check engine lights. But if the machine is experiencing a particular RPM limit, it may indicate a particular problem.

    Common RPM Limits and Causes:

    Idle RPM: 1550 50 Normal Operation

    Maximum Engine RPM: 7800 Rev Limiter Function

    Limp--Home Mode: 1750, Failure with either the ECU, ETB, or PPU components.

    Reverse Mode: 3400 Operator moves reverse handle from forward to position to either neutral or reverse positions.

    Overboost Protection Mode*: 4700 -- 4800
    110: Boost exceeded .8 -- .9 BAR for more than 400ms.
    150: Boost exceeded 1.3 BAR for more than 400ms.

    Engine Temperature Overheat Protection*: 1600 -- 1800 The engine coolant temperature exceeds safe operating
    range.

    Exhaust Manifold Temperature Overheat Protection: 1800 The exhaust manifold freshwater cooling temperature
    exceeds safe operating range.

    * = Indicates a TORQUE REDUCTION running mode. The ECU limits engine RPM by limiting the amount of
    torque generated by the engine. Stated RPM limit is an approximation and changes with current engine operating
    conditions
