This diagnostic trouble code (DTC), SSU 523826.13, is triggered when the wheel angle sensor (WAS) is found to have an invalid calibration, or is not yet calibrated.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.12, is triggered when the Steering System Control Unit (SSU) detects that the wheel angle sensor-axle is not detecting actual steering motion within the allotted time during calibration. This fault tends to occur as additional hours accrue and the steering mechanics loosen.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.10, is triggered when a movement is detected by the wheel angle sensor (WAS) but not by the steering input device (SID). This indicates a discrepancy between the steering wheel input and the actual steering motion detected by the wheel angle sensor.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.07, is triggered when the SSU control unit fails to detect a signal from the wheel angle sensor (WAS) during calibration, despite steering movement being made. The signal from the WAS must be above 1.5 volts when moving from the right steering stop to the left steering stop.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.02, is triggered when the wheel angle sensor (WAS) sends false signals to the SSU control unit during calibration. This indicates an issue with the accuracy of the signals from the sensor during the calibration process.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.01, is triggered when the voltage at the signal line of channel 1 of the wheel angle sensor (WAS) falls below 0.5 volts for longer than 320 milliseconds. This indicates a low voltage condition, potentially due to an open circuit in channel 1 of the steering angle sensor.
- John Deere error SSU codes
This diagnostic trouble code (DTC), SSU 523826.00, is triggered when the voltage at the signal line of channel 1 of the wheel angle sensor (WAS) exceeds 4.5 volts for longer than 320 milliseconds. This indicates an overvoltage condition in channel 1 of the steering angle sensor.
