Troubleshooting Recommendations:

  1. Perform wiring checks between SPDA 4 (A16P3) and SPC (A40BP1).

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.

  2. Disconnect the Pitch Disconnect Lock Solenoid (L50) and perform a wiring check between the SPC (A40AP1) and the Pitch Disconnect Lock Solenoid (L50P1).

    1. If wiring defects are found, repair defective wiring as required and do close out.
    2. If no wiring defects are found, continue with next step.

  3. Replace the Pitch Disconnect Lock Solenoid. Is the fault still present?

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

  4. Replace Stall Protection Computer (SPC).
  5. Do close out.
