CSAS Temperature Sensor Fault
1. Possible Causes
- SENSOR-TEMP DUCT,CSAS [115HW]
- wiring
A. Referenced Information
| REFERENCE | DESIGNATION |
|---|---|
| ASM 215301 | |
| AMM 21-58-00-710-001 | Operational Test of the Conditioned Service Air System without Bleed Air |
| AMM 21-58-11-000-001 | Removal of the Duct Temperature Sensor |
| AMM 21-58-11-400-001 | Installation of the Duct Temperature Sensor |
Subtask 21-58-00-710-058-A ** ON A/C NOT FOR ALL
A. Do the operational test of the conditioned service air system without bleed air AMM 21-58-00-710-001.
4. Fault IsolationSubtask 21-58-00-810-054-A ** ON A/C NOT FOR ALL
A. If the test gives the maintenance message CSAS TEMP SNSR (115HW) or CRITICAL OVTEMP :
Subtask 21-58-00-710-059-A ** ON A/C NOT FOR ALL - replace the SENSOR-TEMP DUCT,CSAS [115HW] AMM 21-58-11-000-001 and AMM 21-58-11-400-001.
- do a check and repair the wiring from:
- the CSAS TEMPERATURE SENSOR (115HW) to the CSAS CONTROL UNIT (100HW) and,
- the CSAS TEMPERATURE SENSOR (115HW) to ground ASM 215301.
B. Do the test as given in the Para. 3.A.
