Troubleshooting Recommendations:
- On the EICAS, are the L FADEC FAIL (Caution) or L FADEC FAULT (Advisory) CAS messages displayed?
- If YES perform the fault isolation for these messages first.
- If NO, continue with next step.
- Access CAIMS active or stored faults. Select displayed message from menu below:
- If no messages are displayed, continue with next step.
- Do the visual check of the engine controlling system.
- If defects are found, rectify as required.
- If no defects are found, continue with next step.
- Swap the left EEC with the right EEC. Is the fault still present?
- If YES, continue with next step.
- If NO, replace defective EEC.
- Perform the troubleshooting in the L FADEC FAIL (Caution) or L FADEC FAULT (Advisory) CAS message pages.
- Do close out.
