Description:

This error code, ASU 524002.31, signals a fault in the pressure control solenoid of the Active Seat Unit (ASU) in John Deere equipment. The fault is identified when the ASU detects electrical current from the pressure control solenoid circuit unexpectedly while it should be off, or fails to detect current when the solenoid is supposed to be on. Such discrepancies suggest issues in the solenoid operation or in the electrical circuit controlling it.

Reaction:

The seat is automatically disabled while this code is active to prevent further damage or incorrect operation, which might affect operator safety and comfort.

Recommendations:

• Inspect Solenoid and Wiring: Check the solenoid for any signs of damage or wear. Inspect the wiring and connections for breaks, shorts, or loose connections that could be causing incorrect current detection.
• Electrical Testing: Conduct electrical tests on the solenoid circuit to verify the integrity of the current flow. Use a multimeter to check for proper voltage and resistance.
• Replace Faulty Components: If any damaged parts are found, replace the solenoid or any faulty wiring immediately to prevent further issues.
• Reset and Recalibrate System: After any repairs or replacements, reset the ASU system and recalibrate it to ensure all components are functioning together correctly.
• System Function Test: Perform a full function test on the seat to ensure that it operates as expected under normal conditions.

Note:

Proactively addressing solenoid and electrical faults is vital for maintaining the functionality and safety of the ASU. Regular maintenance and checks of the electrical systems can help avoid such issues and ensure that the operator’s seat remains functional and safe.
