Troubleshooting Recommendations:

  1. Disconnect SDU connector A228BP1 and DAU connector A18CP1. Perform a continuity check as follows:

    From To Result
    A228BP1-E4 Ground
    A228BP1-F4 Ground
    A228BP1-E4 A228BP1-F4

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

  2. Perform a continuity check as follows:

    From To Result
    A228BP1-E4 A18CP1-H8
    A228BP1-F4 A18CP1-J8

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

  3. Swap DAU 2 with DAU 4. Is the fault still present?

    1. If YES, continue with next step.
    2. If NO, replace DAU 2 and do close out.

  4. Replace the SDU.
  5. Do close out.
