Description:

This error code, PTR 523953.02, indicates that the Power Train Reverser (PTR) control unit has detected a conflict or disagreement among the left hand reverser lever switch inputs, the Park switch input, the Hi/Lo switch inputs, and the Not Neutral relay input. This can occur due to wiring issues, sensor faults, or problems within the control circuitry.

Reaction:

When this error is detected, the PTR control unit may disable or limit the functionality of the speed control lever to prevent potential damage or unsafe conditions. The system may also display a warning message to alert the operator.

Recommendations:

Inspect Switches and Sensors:

• Check the left hand reverser lever switches, Park switch, Hi/Lo switches, and Not Neutral relay for proper operation.
• Ensure all switches and sensors are correctly aligned, clean, and free from damage. Replace if necessary.

Check Wiring and Connections:

• Inspect the wiring and connectors related to the switches and sensors.
• Ensure all connections are secure and free from corrosion, damage, or short circuits.

Test Circuitry:

• Use a multimeter to test the circuitry for the switches and sensors for proper functionality.
• Ensure there are no short circuits, open circuits, or other electrical issues causing the conflict.

Examine Control Unit:

• Verify that the PTR control unit is functioning correctly.
• Check for any diagnostic trouble codes in the control unit that might relate to the sensor inputs.

Update Software:

• Ensure that the PTR control unit software is up-to-date.
• Apply any available software updates or patches from the manufacturer.

Monitor System Operation:

• After addressing the issue, monitor the operation of the speed control lever and associated switches and sensors.
• Ensure that there are no further conflicts or disagreements among the inputs.

Note:

Accurate detection and agreement among the various switch and sensor inputs are essential for safe and efficient operation of the speed control lever. Regular inspection and maintenance of the switches, sensors, and related components can help prevent such issues.
