This diagnostic trouble code (DTC), SSU 522451.14, is triggered when the voltages in channel 1 and channel 2 of the wheel angle sensor (WAS) are not in the correct ratio. The signal voltage of sensor 2 should be half of the signal voltage of sensor 1. The DTC is triggered if the difference is 0.4…

John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 522451.01, is triggered when the voltage at the signal line of channel 2 of the wheel angle sensor (WAS) falls below 0.25 volts for longer than 320 milliseconds. This indicates a low voltage condition, potentially due to an open circuit in channel 2 of the wheel angle sensor.

John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 522451.00, is triggered when the voltage at signal line 986 of channel 2 of the wheel angle sensor (WAS) exceeds 2.25 volts for longer than 320 milliseconds. This indicates an overvoltage condition in channel 2 of the wheel angle sensor.

John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 522394.09, is generated when the information from the Terrain Compensation Module (TCM) integrated in the StarFire ITC receiver is not recognized on the CAN BUS after four attempts. This indicates a problem in the CAN BUS communication or loose connectors.

John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 522387.07, is triggered when, despite a steering movement being commanded, the SSU control unit fails to detect a signal from the wheel angle sensor (WAS) or receives a signal that is too low. This indicates a failure in detecting the expected steering movement.

John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 522273.00, is triggered when the steering control valve (Y49) receives a control signal from the SSU control unit that is out of the valid range high (over 85% of the system voltage). This indicates an overvoltage condition in the control signal.
