Description:

This error code, ACU 000628.02, is associated with a failure in the End-of-Line (EOL) memory during the system’s startup sequence. The EOL data, crucial for the initialization and configuration settings, fails to load or verify correctly, indicating potential corruption or loss of data.

Reaction:

In response to this data fault, the control unit automatically defaults the system to a neutral position, preventing any actions that could lead to unsafe conditions due to incorrect configuration or operational data.

Recommendations:

• Attempt to re-download and install the latest software for the ACU to correct any discrepancies in the EOL data. Ensure that the software version is compatible with your machine’s specifications.
• Perform a full system reset to clear any residual errors in the memory that might be affecting the start-up processes.
• If the problem persists after updating the software, it may be necessary to replace the memory module or consult with a John Deere certified technician for a deeper diagnostic evaluation.

Note:

While EOL data faults can often be resolved through software updates, repeated occurrences may indicate a more severe hardware issue that requires professional attention. Ensure that all software maintenance is conducted as part of regular equipment checks to minimize downtime and operational disruptions.
