Troubleshooting Recommendations:

  1. Interchange CPC 2 with CPC 1. 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.
