Troubleshooting Recommendations:

  1. Carry out a quantity check of the hydraulic system 2 and verify that the right engine firewall hydraulic shutoff valve is physically fully open.

    1. If the right engine firewall hydraulic shutoff valve is fully open, go to step 3.
    2. If the right engine firewall hydraulic shutoff valve is not fully open, continue with next step.

  2. Perform the operational test of the right engine firewall hydraulic shutoff valve and replace if necessary.

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

  3. Start the right engine and check the hydraulic system 2 pressure.

    1. If the pressure is low, replace the EDP 2 and do close out.
    2. If the pressure is good with the engines running, continue with next step.

  4. Disconnect the EDP 2A pressure switch connector S37P1 and install a jumper between S37P1-A and S37P1-B.

    1. If system checks are good, go to step 7.
    2. If fault remains, remove jumper and install connector S37P1 and continue with next step.

  5. Swap DAU 3 with DAU 2.

    1. If system checks are good, replace DAU 3 and do close out.
    2. If fault remains, continue with next step.

  6. Perform a wiring check between the EDP 2A pressure switch and the DAU 3.

    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.

  7. Replace the pressure switch.
  8. Do close out.
