Troubleshooting Recommendations:
- Using PMAT, access CAIMS active faults. Are there any active or stored faults related to the Data Aquisition System displayed?
- If YES, perform troubleshooting for the corresponding troubleshooting in SmartFix Plus.
- If NO, continue with next step.
- Remove DAU 1 to get access to the connector A17AP1 and disconnect A253P1 from CTRL WHL FTU PILOT. Perform a continuity check as follows:
From To Result A17AP1-D11 A253P1-4 A17AP1-E11 A253P1-5 A17AP1-SH (shield) A253P1-SH (shield) - If there is no continuity, repair defective wiring as required and do close out.
- If there is continuity, continue with next step.
- Perform a continuity check as follows:
From To Result A17AP1-D11 Ground A17AP1-E11 Ground A17AP1-SH (shield) Ground - If there is continuity, repair defective wiring as required and do close out.
- If there is no continuity, continue with next step.
- Replace DAU 1.
- Do close out.
