Troubleshooting Recommendations:

  1. Perform wiring checks between SPDA 1 and the Right EEC.

    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. Swap SPDA 1 with SPDA 3.

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

  3. Replace Right EEC.
  4. Do close out.
