SFA 523903.07 (SFA )

Code: 523903.07

Shortcode:

Description:

This error code indicates that the front axle is not responding to the lower command. The position sensor detects no downward movement for longer than 10 seconds, which may be caused by mechanical obstructions, faulty sensors, or issues within the hydraulic system.

Reaction:

When this error code is triggered, the front axle will not lower as commanded, leading to potential handling issues and reduced ride comfort.

Recommendations:

  • Inspect Hydraulic System:
    • Check the hydraulic fluid levels and ensure there are no leaks. Inspect the hydraulic pump and lines for proper operation.
  • Check for Mechanical Obstructions:
    • Inspect the front axle for any mechanical obstructions or debris that might prevent downward movement. Clear any obstructions found.
  • Test Position Sensor:
    • Test the position sensor to ensure it is functioning correctly. Replace the sensor if it is found to be defective.
  • Verify Solenoid Operation:
    • Check the lower command solenoid for proper operation. Ensure it is receiving the correct signals and replace it if necessary.
  • Consult Technical Support:
    • If the issue persists, consult technical support or the manufacturer for further assistance in diagnosing and resolving the problem.

Note:

Regular maintenance of the hydraulic system and sensors is crucial for the proper functioning of the front axle. Address any issues promptly to avoid further complications.
