Troubleshooting Recommendations:
- Remove the DAU 4 to get access to the connector A31AP1 and rudder pedal dual transducer to get access to the connector MT219P1. Perform a continuity check as follows:
From To Result A31AP1-B7 MT219P1-6 A31AP1-C7 MT219P1-7 - If there is no continuity, repair or replace defective wiring as required and do close out.
- If there is continuity, continue with next step.
- Perform a continuity check as follows:
From To Result A31AP1-B7 Ground A31AP1-C7 Ground - If there is continuity, repair or replace defective wiring as required and do close out.
- If there is no continuity, continue with next step.
- Swap DAU 4 with DAU 2.
- If system checks are good, replace DAU 4 and do close out.
- If fault remains, continue with next step.
- Replace the Rudder Pedal Dual Transducer.
- Do close out.
