    We got a brand new unused 966K wheel loader 2012 year built, come to us 2014 year. It was ok, but later after a while we found this problem

    Steering Malfunction, E192-3 Shundown safely
    Steer Motor Torq Snsr Voltage High, 2866-3 Shundown safely.

    Anyone knows what could be the problem, and how to fix it? Is it expensive to fix this?
    The machine is still never used till now.

    Thanks.

    On our stupid Volvo's, a lot of the time,
    turning off the battery main disconnect, master switch,
    for 10 minutes, fixes a lot of electrical issues like that. Lol.
    It could be a sensor starting to go out/or loose connection, giving an infrequent error code to the computer.
    If that doesn't work, the mechanic's will try to cancel the code either by using the keypad on the dash or hooking up a computer.
    And ordering up a new sensor.

    Maybe not much help, but maybe something to try.

    There is a reason they only made the K's for a couple years.

    As others have said a Serial Number would be a great start.

    Meantime I am of the opinion that both your Codes/Events are related. The E192 Event is activated when ECM does not receive expectant steering position signals. There can be a number of reasons for this but one of them is "2866 (Steering Control Force Feedback Motor Torque Sensor)" so logically your 2866-03 Diagnostic Code is the most likely root cause of the E192 Shutdown request.

    The 2866-03 indicates that the ECM has detected that the duty cycle (voltage) of the Steering Control Force Feedback Motor Torque Sensor circuit is above the high threshold. There is a detailed troubleshooting procedure for this Code, so if you want to drop me a PM with your email address I'll send it to you. It will require a digital multimeter and possibly the Electrical Schematic for the machine, but with the Serial Number I can send you that as well.
