    ABS/DTC fault

    I've a problem with my 2015 s1000xr, while on the spin the ABS/DTC lights start flashing, rev limiter starts glitching and speedo goes to 3 lines.
    GS-911 showed 3 faults under the ABS section
    Under voltage to a sensor
    Over voltage to a sensor
    Movement in the rear wheel sensor
    What causes them to come up and how to fix them issues?
    Thanks

    I would :
    1) check the battery connections
    2) check the health of your battery

    a GS-911 unit or MotoScan then it can read your ecu

    He’s already done that, quoted the results in his post.

    As well as what SimonUK suggested, I would check the rear wheel sensor and wiring which is run with the rear brake hose. The sensor can be damaged when the wheel comes in and out. :028:

    Over/Under voltage indications may indicate a poorly REG/REC.

    Movement sensor issue may be a duff swingarm movement sensor..??

    No loose connection on the battery,
    Battery is only  3/4 months old, it starts first time every time

    The GS-911 stated that both sensors are okay and there is no physical movement on the rear wheel sensor

    How would I check if its the REG/REC? Replace it
    with a new one ?
    No physical movement on the abs sensor, is there another sensor in the swing arm?

    Put a Multimeter on battery and see what is doing.

    The sensor is fitted through the rear brake carrier. The lead runs back up the swing arm, clipped to the brake hose. See picture.
    The reluctor ring, which the sensor reads, is fitted to the rear wheel. They are mounted very close to each other and can easily be damaged.
    If the GS911 is highlighting faults in the ABS section including rear wheel sensor, then it would make sense to check the sensor/ring/cable for damage or movement.
    It may need removal to check and test properly (at least the rear wheel).
