  • SSU 523826.14 – B139 Steering Angle Sensor Recognizes No Movement

    John Deere error

    This diagnostic trouble code (DTC), SSU 523826.14, is generated when the wheel angle sensor (WAS) does not detect any steering movement even though the steering wheel position sensor (B138) transmits steering signals to the SSU. This indicates a discrepancy between the steering wheel input and the actual steering motion.
