Troubleshooting Recommendations:

  1. Remove the DAU 1 to get access to the connector A17AP1 and disconnect the connector C45P1 from oil tank probe. Perform a continuity check as follows:

    From To Result
    A17AP1-D5 C45P1-4
    A17AP1-C5 C45P1-5
    A17AP1-SH (shield) C45P1-SH (shield)

    1. If there is no continuity, repair or replace defective wiring as required and do close out.
    2. If there is continuity, continue with the next step.

  2. Perform a continuity check as follows:

    From To Result
    A17AP1-D5 Ground
    A17AP1-C5 Ground
    A17AP1-SH (shield) Ground

    1. If there is continuity, repair or replace defective wiring as required and do close out.
    2. If there is no continuity, continue with the next step.

  3. Swap DAU 1 with DAU 3.

    1. If system checks are good, replace DAU 1 and do close out.
    2. If fault remains, continue with next step.

  4. Replace Oil Tank Probe.
  5. Do close out.
