Troubleshooting Recommendations:

  1. Perform wiring checks between ACU (A227P1), JB6 and SDU (A228BP1).

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

  2. Perform wiring checks between ACU (A227P1), JB6 and HPA (A229BP1).

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

  3. Replace ACU.

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

  4. Replace SDU.

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

  5. Replace HPA.

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

  6. Replace PCB5/JB6.
  7. Do close out.
