Description:

This information for the operator (DTC) UIC 001504.31 is triggered if the reverse drive lever position “power zero” is activated for longer than 30 seconds without any valid signal indicating that the operator is present (operator on seat, clutch, or brake pedals depressed).

Reaction:

When this informational code is triggered, it serves as a warning to the operator that the vehicle is in a potentially unsafe state where it may not respond as expected due to the absence of an operator presence signal.

Recommendations:

• Verify Operator Presence Sensors:
  • Check the sensors for operator presence (seat switch, clutch pedal switch, brake pedal switch) to ensure they are functioning correctly.
  • Test each sensor to confirm it sends a valid signal when the operator is present.
• Inspect Signal Connections:
  • Ensure that all wiring and connectors related to the operator presence detection system are secure and free from damage or corrosion.
• Review Operator Procedure:
  • Make sure the operator is aware of the need to maintain a valid presence signal when using the reverse drive lever.
• Consult Technical Support:
  • If the issue persists after checking the sensors and connections, contact John Deere technical support for further assistance.

Note:

This code is primarily informational and serves to alert the operator to a potential safety concern. Regular checks of the operator presence detection system can help prevent such alerts.
