Description:

This diagnostic trouble code (DSM 000628.02) indicates an internal fault within the control unit, specifically involving the EEPROM module. EEPROM faults can affect the control unit’s ability to store and retrieve critical operational data.

Reaction:

When an internal fault occurs, the control unit may enter a safe mode or shut down certain functionalities to prevent further issues. This is a precautionary measure to avoid operational failures or data corruption.

Recommendations:

• Diagnose Internal Module: Perform detailed diagnostics on the EEPROM and other internal modules to identify the fault.
• Check for Software Updates: Ensure the control unit firmware is up-to-date, as updates may include fixes for internal module issues.
• Replace Faulty Components: If the EEPROM or other internal components are found to be faulty, replace them with new or known-good units.
• Perform System Reset: After replacing faulty components, reset the control unit to clear the fault code and restore normal operation.
• Test System Functionality: Conduct comprehensive testing to ensure the control unit is functioning correctly and that the internal fault has been resolved.

Note:

Internal faults in the control unit can lead to significant operational issues. Regular software updates and proactive maintenance are essential to minimize the risk of such faults and ensure reliable system performance.
