XSC codes

Comprehensive Guide to John Deere XSC Error Codes and Fault Codes

The John Deere XSC control software, integrated within the AutoTrac™ automatic steering system, plays a critical role in managing the vehicle’s steering functions. Working alongside the XMC control software, it processes signals from various sensors and modules to ensure precise and efficient steering. Below is a detailed list of common John Deere XSC fault codes and their descriptions to help diagnose and resolve issues effectively.

John Deere XSC Fault Codes List

Understanding the XSC diagnostic trouble codes is essential for maintaining the optimal performance of the AutoTrac™ system. Here are some of the most frequently encountered fault codes:

1. XSC 523824.16 – Steering Wheel Position Sensor, Frequency at Channel 2 Too High

  • Description: This code indicates that the frequency at channel 2 of the steering wheel position sensor exceeds 300 Hz.
  • Occurrence: Detected in the steering control unit.
  • Impact: Limited or no function of the control unit.

2. XSC 523821.02 – Incompatible Harness on Steering Control Unit (AutoTrac™)

  • Description: Indicates that the control unit is connected to an incorrect harness.
  • Occurrence: Detected during harness connection checks.
  • Impact: Limited or no function of the control software.

3. XSC 523826.00 – Wheel Angle Sensor Channel 1, Voltage Too High

  • Description: Voltage over 4.5V registered at channel 1 of the wheel angle sensor.
  • Occurrence: Detected in the wheel angle sensor channel.
  • Impact: Limited or no function of the control unit.

4. XSC 524055.12 – Control Software Internal Fault

  • Description: A fault occurs when the software is launched.
  • Occurrence: Detected during control software startup.
  • Impact: Limited or no function of the control software.

5. XSC 523925.09 – Incorrect CAN BUS Message, Information from XMC Control Software

  • Description: Data transfer problem between XMC and XSC control software due to intermittent or non-existent CAN messages.
  • Occurrence: Detected in the CAN BUS network.
  • Impact: Limited or no function of the control software.

Key Components and Signal Processing

The XSC control software receives and processes signals from:

  • Steering Wheel Position Sensor
  • Wheel Angle Sensor
  • LIN Bus Module (Shift Console)
  • LIN Bus Module (Position H)

These signals are compared with those of the XMC control software before transmitting to:

  • Solenoid Valve for Steering Control Valve (Enable Valve)
  • Solenoid Valve for Steering Control Valve (Left Turn)
  • Solenoid Valve for Steering Control Valve (Right Turn)

Maintaining Optimal Performance

For optimal performance of the John Deere AutoTrac™ system, regularly monitor and address any XSC fault codes. Proper maintenance and timely resolution of these codes will ensure efficient and accurate steering control, enhancing the overall functionality of your equipment.

By understanding and utilizing this John Deere XSC diagnostic trouble codes list, you can effectively diagnose and troubleshoot issues within the AutoTrac™ system, ensuring reliable and precise operation.
