Troubleshooting Recommendations:
- Check if the CAS message ADC 3 FAIL is posted.
- If the CAS message exists, troubleshoot it first and continue with next step.
- If the CAS message does not exists, continue with next step.
- Perform wiring checks between MADC 3 and EEC 1 CH B.
- If wiring checks are not good, repair defective wiring as required and do close out.
- If wiring checks are good, continue with next step.
- Swap MADC 3 with MADC 2.
- If system checks are good, replace MADC 3 and do close out.
- If fault remains, continue with next step.
- Replace Left EEC.
- Do close out.
