Hi

My 912iS has 350 hours so far and Lane A light came on recently. Dongle check says Start Ignition Driver Failure. Went through the manuals and could not find ignition driver. Can anyone enlighten me?

Update: Dongle check says (Ignition/Injector Driver Failure)

Thanks

    When did it come on? After start-up? During cruise?

    After start up

    Sounds like a crank position sensor failure, did it go away after a power cycle? (Lanes reset, off/on)

    We checked all coils, high tension leads and spark plugs. Still getting the same error. Ignition/Injector Driver Failure (Communication Error)

    Does anyone know what's going on with the engine?

    Are you sure it is not a Fuel Injector issue?

    Each cylinder has 2 fuel injectors.
    The engine starts on only one of the injectors.
    Once the ECM confirms a good start, it begins alternating injectors on every other cycle.
    If the bad injector is not the one used for starting, the fault may not appear until 3-5 seconds after the RPM's stabilize.
    Once the ECM identifies the problem it removes the bad injector from the mix and the engine runs perfectly normal.
    Just before the light comes ON, you might hear a very brief misfire/hesitation that quickly disappears.

    The good part of redundant systems is that the engine keeps making full power.
    The Bad part is that the failures produce no symptoms other than a warning light.
    It makes troubleshooting an otherwise perfectly good engine a challenge.

    The "Ignition/Driver Failure" may indicate the Fuel Injector Circuit is Failing to Drive the Injector.
    The "Communication Error" may indicate that the ECM/Driver does not "See" the Injector electrically.
    It could be a wiring/connection problem.

    Try re-seating the connectors on the injectors.
    Have a look inside the connections while you have them off to see if any look suspicious. Corrosion/Water?

    If all else fails...
    Remove one Fuel Injector Connection at a time. Start the Engine.
    The One that does Not produce an Additional error is the Bad One.
    The One that causes a cylinder to fail completely is the one Next to the Bad One!
