PTR 000162.31 – High, Low Switch Stuck On

PTR 000162.31 (PTR 162.31)

Code: 000162.31

Shortcode: 162.31


This error code, PTR 000162.31, is generated by the Power Transmission Reverser (PTR) control unit when it detects that either the High or Low momentary switch remains in the actuated position for longer than 30 seconds. This can occur due to a faulty switch, physical obstruction, or an issue within the control circuitry.


When this error is detected, the PTR control unit may disable the affected switch functionality to prevent further issues. The system may also alert the operator with a warning message or indicator light.


Inspect Switches:

  • Check the High and Low momentary switches for proper operation.
  • Ensure the switches are not physically stuck, damaged, or obstructed. Replace if necessary.

Check Wiring and Connections:

  • Inspect the wiring and connections associated with the High and Low switches.
  • Ensure all connections are secure and free from damage or corrosion.

Test Switch Circuitry:

  • Use a multimeter to test the switch circuitry for proper functionality.
  • Ensure there are no short circuits or other electrical issues causing the switch to remain actuated.

Examine Control Unit:

  • Verify that the PTR control unit is functioning correctly.
  • Test the control unit inputs for proper voltage levels when the switches are activated.

Update Control Unit Software:

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

Monitor Switch Operation:

  • After addressing the issue, monitor the operation of the High and Low switches.
  • Ensure that the switches function as intended and do not remain stuck in the actuated position.


Regular inspection and maintenance of the switch circuitry and control unit can help prevent such issues. Ensure that operators are trained to recognize and report switch problems promptly.
