Description:

This operator information (diagnostic trouble code), EPC 523966.31, is generated when the comehome mode is activated (K07/04 or K03/04 connector for comehome feature in “COME HOME” position). The comehome mode can only be activated within the first 2.5 seconds after starting the engine when the connector for the comehome feature is in “COME HOME” position and the reverse drive lever is in neutral position.

Reaction:

When this error is detected, the system alerts the operator about the activation of the comehome mode, which allows for limited operation of the vehicle in emergency situations.

Recommendations:

Verify ComeHome Mode Connector:

• Ensure that the connector for the comehome feature (K07/04 or K03/04) is in the correct position. If the comehome mode is not intended to be activated, ensure the connector is not in the “COME HOME” position.

Inspect Reverse Drive Lever:

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

Educate Operator:

• Ensure that the operator understands the purpose and conditions for activating the comehome mode and the importance of the correct connector position.

Reset and Test System:

• After addressing the issues, reset the system and test the comehome mode activation to ensure proper operation and that the error code does not reoccur.

Note:

Understanding the comehome mode and its conditions for activation is important for emergency vehicle operation. Regular checks and proper positioning of connectors help prevent unintended activations.
