Description:

This code indicates that the engine hour meter data is either missing or has an abnormal update rate over the CAN network. This could be caused by communication issues, faults in the hour meter sensor, or problems with the control module managing the data.

Reaction:

The engine control system may not accurately track the total hours of operation, which can affect maintenance schedules and operational logs. A warning might be displayed on the dashboard.

Recommendations:

• Inspect CAN Network Wiring:
  • Check the CAN network wiring for any damage, loose connections, or corrosion.
  • Ensure all connectors are properly seated.
• Test Hour Meter Sensor:
  • Verify that the hour meter sensor is functioning correctly and transmitting data at the correct rate.
  • Replace the sensor if it is found to be faulty.
• Check Control Modules:
  • Ensure the control modules managing the hour meter data are functioning correctly and up to date.
  • Update the software or firmware to the latest versions.
• Verify Data Integrity:
  • Use diagnostic tools to check the integrity and update rate of data being transmitted over the CAN network.

Note:

Maintaining the CAN network and ensuring all components are properly connected and functioning can help prevent data transmission issues.
