Description:

This diagnostic trouble code (DTC) is generated if the reverse drive lever position “Power Zero” is activated for longer than 30 seconds without a valid signal indicating operator presence (such as the operator being on the seat, or the clutch or brake pedals being depressed).

Reaction:

• Information is provided to the operator indicating the issue.
• No automatic corrective action by the control software, but potential safety concerns due to lack of operator presence.

Recommendations:

Check Operator Presence Sensors:

• Verify that all operator presence sensors (seat switch, clutch pedal switch, brake pedal switch) are functioning correctly.
• Replace any faulty sensors to ensure they provide valid signals.

Inspect Wiring and Connections:

• Check the wiring and connections associated with the operator presence sensors for damage or disconnections.
• Repair or replace any damaged wiring or connectors.

Verify Lever Position Sensor:

• Ensure that the sensor for the reverse drive lever position “Power Zero” is operating correctly.
• Replace the sensor if it is faulty or giving incorrect readings.

Update Control Software:

• Ensure that the control software is up-to-date with the latest version from the manufacturer.

Consult Technical Support:

• If the issue persists, consult technical support for further diagnostic procedures or potential software issues.

Note:

Regular maintenance and checks of all operator presence sensors and associated wiring can prevent issues related to false operator presence signals. Ensuring all sensors are clean and unobstructed is crucial for accurate readings.
