If there is no FMS 3 installed, disregard the fault code. Make sure that FMS is operative and there are no active/stored faults for FMS 3.
- If there are active faults related to FMS 3, troubleshoot and fix active faults before proceeding with further steps
- If there are stored faults related to FMS 3, make sure that faults did not happen at the same time as ADLU ARINC RX 4 FAULT. If that is the case, then start with a wiring check between the Airborne Data-Link Unit (ADLU) and FMS 3

Troubleshooting Recommendations:
- Operate the Airborne Data-Link System via FMS 3 using VHF network to request a "dummy" flight plan provided by service provider.
NOTE: Make sure aircraft is within VHF range of ACARS data communication ground station and VHF #3 is operative. Do the initialization of the Flight Management System (FMS). - When the message FLT PLAN RECEIVED is shown on the FMS CDU 3, activate the flight plan, make sure the flight plan is loaded and the FMS CDU 3 automatically shows the ACTIVE FLT PLAN page 1/1. Is the ACTIVE FLT PLAN page 1/1 shown?
- If YES, verify that CAIMS fault code 2320014TDY "ADLU ARINC RX 4 FAULT" is not displayed on PMAT and do close out.
- If NO, continue with next step.
- Perform wiring checks, short to ground and pin/socket retention check between the Airborne Data-Link Unit (ADLU) connector A239AP1, A239BP1 and FMS 3/IAC 3 connector A12CP1. Is it satisfactory?
- If NO, repair or replace the defective wiring as required per WM 20-12 and do close out.
- If YES, continue with next step.
- Replace the Airborne Data-Link Unit (ADLU) (ADLU ARINC 429 Receiver #4 is faulty).
- Do close out.
