This error code, PTR 000628.02, indicates that the Power Train Reverser (PTR) control unit has detected a failure in the End-of-Line (EOL) memory check sum. This typically means that the stored data has been corrupted or is not matching the expected values.

Reaction:

When this error is detected, the PTR control unit may limit or disable certain functionalities to prevent potential issues. The system will likely display a warning message to alert the operator.

Recommendations:

Verify EOL Memory Integrity:

• Check the EOL memory for any signs of corruption or errors.
• Use diagnostic tools to read and verify the memory content against expected values.

Update Control Unit Software:

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

Reprogram EOL Memory:

• If the memory is found to be corrupted, reprogram the EOL memory with the correct data.
• Follow the manufacturer’s guidelines for reprogramming procedures.

Inspect Control Unit:

• Verify that the PTR control unit is functioning correctly and is free from physical damage.
• Replace the control unit if it is found to be defective.

Check Electrical Connections:

• Inspect the wiring and connectors related to the PTR control unit and EOL memory.
• Ensure all connections are secure and free from corrosion or damage.

Monitor System Operation:

• After addressing the issue, monitor the system operation to ensure the EOL check sum error does not reoccur.
• Record any anomalies or recurring issues for further diagnosis.

Note:

Maintaining the integrity of the EOL memory is crucial for the proper operation of the PTR control unit. Regular software updates and careful handling of the control unit can help prevent such errors.
