Troubleshooting Recommendations:

  1. Interchange CPC 1 with CPC 2. Does the fault clear?

    1. If YES, replace defective CPC and do close out.
    2. If NO, power-up each CPC one at the time and see if it generates a DELTA P (Warning).
    3. Replace the CPC that generates the CABIN DELTA P (Warning) and do close out.

  2. Normalize the CPC position, check for CABIN DELTA P (Warning), select MAN and then back to AUTO PRESS, make sure the fault is not present.
  3. Reselect the MAN and then back to AUTO PRESS again, make sure the fault is not present.
  4. Do close out.
