Troubleshooting Recommendations:

  1. Using the Bus Reader, read label 040, 203 and 211 from DAU 2. Make sure the labels are present and valid.

    1. If all three labels are present, then replace EVSHC and do close out.
    2. If all three labels are not present, continue with next step.

  2. Using the Bus Reader, read label 271 coming out of the LGECU Ch A. Make sure the labels are present and valid.

    1. If the label(s) is missing or invalid, replace LGECU and do close out.
    2. If the label(s) is valid, continue with next step.

  3. Using the Bus Reader, read WSP 38 Data set 3 from DAU 3 and DAU 4. Make sure the WSP are present and valid.

    1. If the WSP is missing or invalid, replace defective DAU and do close out.
    2. If the WSP is valid, continue with next step.

  4. Using the Bus Reader, read WSP 8 and WSP 2 from MADCs. Make sure the WSPs are present and valid.

    1. If the WSP is valid on one of the MADCs, do close out.
    2. If the WSP is missing or invalid on one of the MADCs, continue with next step.

  5. Replace defective MADC.
  6. Do close out.
