    ABS & DSC lights on

    Hello my car is acting up, the dsc & brake light are yellow. I pulled the codes
    ABS
    ~wheel speed sensor FL start recognition - Yellow
    ~Steering angle sensor signal not plausible offset - Yellow
    ~Vehicle power <9volt - Yellow
    ~Wheel speed sensor FR start recognition v_comparison - Yellow
    ~Steering angle sensor internal - RED
    Electronic Gear box control
    ~CAN Wheel speeds - Yellow

    After clearing the codes the Gearbox control CAN wheel speed, hasnt shown up although i still haven't done another test drive yet.

    Could have a low battery voltage have a affect on these sensor not wanting to read?

    Is there a short in the wheel speed sensors?

    BMW electronics are sensitive to inadequate voltage levels.
    Remove battery, charge overnight, if level not near 12.7v-replace battery.

    Check for clean, snug connections at each individual speed sensor.
