EPC 524023.31 – A82 Reverse Drive Lever, Forward Switch or Reverse Switch Closed, But NotNeutral Switch Open

EPC 524023.31 (EPC )

Code: 524023.31



This error code, EPC 524023.31, is generated when the control unit receives an incorrect switch signal combination from the reverse drive lever. Specifically, it indicates that the forward or reverse switch is closed while the not-neutral switch is open, suggesting a potential issue with the switch signals or an incorrect lever position.


When this error is detected, the system may prevent certain operations or issue a warning to indicate that the switch signals are inconsistent, which could affect vehicle control and safety.


Inspect Reverse Drive Lever Switches:

  • Check the condition and functionality of the forward, reverse, and not-neutral switches on the reverse drive lever. Replace any defective switches.

Verify Switch Signals:

  • Ensure that the switch signals from the reverse drive lever are consistent and correct. The not-neutral switch should not be open when the forward or reverse switch is closed.

Inspect Wiring and Connections:

  • Inspect the wiring and connections to the switches for any signs of damage, loose connections, or corrosion. Repair or replace as necessary.

Check for Mechanical Issues:

  • Ensure that there are no mechanical issues with the reverse drive lever that could cause incorrect switch positioning.

Reset and Test System:

  • After addressing the issues, reset the system and test the reverse drive lever switches to ensure they operate correctly and that the error code does not reoccur.


Proper functionality and consistency of the reverse drive lever switches are crucial for safe and reliable vehicle operation. Regular maintenance and inspection help prevent issues related to incorrect switch signals.
