Troubleshooting Recommendation:
- Check if the following CAS messages are posted:
- FMS#2 FAIL (cyan)
- ADC 2 DEGRADED (cyan)
- ADC 3 FAIL (cyan)
- If YES, continue with next step.
- If NO go to step 3.
- Pull ESS BUS TRU 1 CB, (To drive DCPC reconfiguration) Are the CAS messages posted?
- If YES, continue with next step.
- If NO, DCPC contactor K2 is highly suspected, inspect the contactor.
- Using the PMAT, access the Active Faults/Stored Faults as per AMM Tasks.
