The problem came slowly, at first after 5mn of fly, the light on the Lane A turn on and stay until the engine stop. Now the light is on full time and the engine run rough (as I know the Lane B is a spare one with degraded mode)

We connect the BUDS and read any fault and specialy one : 0x4099277D (see the pic) but impossible to find what did it mind? asking to the French importe he don't know to...

Can you help me?

Many thanks

    You are looking at the live status screen and it is reporting a bad sensor reading.

    Look at the log screen to see the sensor's identity.

    The Error is a Reference Voltgage Below Range.

    The "Reading" is the value it is reading, "4099277D",  the "0x" before the number tells you that the number is Hexadecimal.

    The Map Sensors have a history of unplugging themselves because the wire harness is secured a bit too tightly.

    Once a Lane light comes ON, it will stay ON indefinetly, until the lane is Power cycled.  ON > OFF > ON.

    The light will NOT go out on its own, even if the fault clears.  You have to reset it.
