Troubleshooting Recommendations:

  1. Pull and reset the PSEU gear system circuit breakers CB1-C13, CB1-C14,CB2-C13, CB2-C14.

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

  2. Check for 28 VDC on PSEU A9BP1 (pins 3A, 4A, 3C, 4C, 7K, 8K, 7H, 8H) and Ground A9BP1 (pins 3H, 4H, 3K, 4K, 7A, 7C, 8C). Repair as required.

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

  3. Do wiring check between PSEU A9CP1 (pins 1B, 2B) and IAPS A4P1 (pins 61, 62). Repair as required.

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

  4. Do wiring checks between PSEU A9CP1 (pins 1B, 2B) and DCU A14DP1 (pins 1A, 1B). Repair as required.

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

  5. Do wiring checks between PSEU A9AP1 pin 15H and MT142P1 pin A (R Reservoir Temp Switch MT142). Repair as required.

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

  6. Do wiring checks between PSEU A9AP1 pin 15H and MT134P1 pin A (R Reservoir Temp Switch MT134). Repair as required.

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

  7. If possible, download and have field service review the PSEU NVM. Further troubleshooting will depend on results of the PSEU NVM.
  8. Replace PSEU.
  9. Do close out.
