Troubleshooting Recommendations:

  1. Make sure circuit breakers are IN. Check EMSCDU for the following circuit breakers are in Gear CTL B PWR 2 and Gear CTL B PWR 1.
  2. Confirm voltage is present by looking in CAIMS System Diag. Select ATA 24 then select SEC PWR DIST. ASSY. 2A Then select LRU Test. You can now locate the label by the Index or go directly to Label 010-017 and select load which will give you Label 010 Load 1-SPDA 2A, confirm page and will bring you to load 2 all values will show in red to select is made and voltage will show voltage or will show absent.

    1. If voltage is good, go to step 4.
    2. If voltage is absent, continue with next step.

  3. Swap SPDA 2 with SPDA 3.

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

  4. Re-seat LGECU.

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

  5. Replace LGECU.
  6. Do close out.
