Troubleshooting Recommendations:
- The CAS message ADC 2 FAIL is posted, troubleshoot it first.
- If system checks are good, do close out.
- If fault remains, continue with next step.
- Perform wiring checks between MADC 2 and EEC 2 channel A.
- 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 2 with MADC 3.
- If system checks are good, replace MADC 2 and do close out.
- If fault remains, continue with next step.
- Replace EEC 2.
