Description:

This operator information (diagnostic trouble code), EPC 524020.31, is generated when the EPC control unit detects an active forward, reverse, or not-neutral switch during the starting procedure. This indicates that the reverse drive lever is not in the neutral position during startup, which may be due to operator error or a malfunctioning switch.

Reaction:

When this error is detected, the system may prevent the vehicle from starting or issue a warning to ensure the reverse drive lever is in the correct position before startup.

Recommendations:

Verify Reverse Drive Lever Position:

• Ensure that the reverse drive lever is in the neutral position during startup.

Inspect Switches:

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

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.

Educate Operator:

• Ensure that the operator understands the correct procedure for starting the vehicle and the importance of the reverse drive lever being in the neutral position.

Reset and Test System:

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

Note:

Proper use and positioning of the reverse drive lever during startup are essential for safe vehicle operation. Regular maintenance and inspection can prevent issues related to switch activation.
