Troubleshooting Recommendations:
- Access CAIMS Systems Diagnostics with pack off and cold, verify if data is valid and matches opposite side.
- If data is valid, monitor next flight and do close out.
- If data is not valid, continue with next step.
- Swap Pack Discharge Temperature Sensor 1 with Pack Discharge Temperature Sensor 2.
- If system checks are good, replace Pack Discharge Temperature Sensor 1 and do close out.
- If fault remains, continue with next step.
- Perform wiring checks between Pack Discharge Temperature Sensor and ACSC 1.
- If the wiring checks are not good, replace the defective associated wiring and do close out.
- If the wiring checks are good, continue with next step.
- Swap DAU 1 with DAU 2.
- If system checks are good, replace DAU 1 and do close out.
- If fault remains, continue with next step.
- Perform a wiring checks between Pack Discharge Temperature Sensor and DAU 1.
- If the wiring checks are not good, replace the defective associated wiring and do close out.
- If the wiring checks are good, continue with next step.
- Replace ACSC 1.
- Do close out.
