Troubleshooting Recommendations:

  1. Open the engine Cowls.
  2. Measure for 28 VDC at the RH SAV solenoid channel B (P1066).

    1. If there is 28 VDC, go to step 4 (when the SAV is commanded open).
    2. If there is no 28 VDC, continue with next step.

  3. Perform wiring checks between the SPDA 1 (A13P1) and the EEC 2 (P1048).

    1. If wiring checks are not good, repair defective wiring as required and go to step 8.
    2. If wiring checks are good, continue with next step.

  4. Perform wiring checks between the EEC 2 (P1046) and the RH SAV (P1066).

    1. If wiring checks are not good, repair defective wiring as required and go to step 8.
    2. If wiring checks are good, continue with next step.

  5. Swap SPDA 1 with SPDA 4. Is the fault still present?

    1. If NO, replace SPDA 1 and go to step 8.
    2. If YES, continue with next step.
      NOTE: You may swap if there is no 28 VDC between the SPDA 1 and the EEC 2.

  6. Swap the Right SAV with Left SAV between engines. Is the fault still present?

    1. If NO, replace Right SAV and go to step 8.
    2. If YES, continue with next step.

  7. Replace the EEC 2.
  8. Close the engine cowls.
  9. Do close out.
