A. Test
R (1) Do the operational test of the FADEC 2 on the ground (with engine non R motoring) (Ref. AMM TASK 73-29-00-710-040).
4. Fault Isolation
_______________
A. The PS13 signal is part of the PMUX option only used for Engine Condition Monitoring.
NOTE : If the engine is not equipped in a PMUX configuration, you have
____
two options:
- replace the engine Identification Connector by a connector configured as Non PMUX to definitively avoid further generation of this fault message,
- ignore this fault message.
NOTE : The fault message is generated if the PS13 sensor signal is
____
invalid or out of range.
(1) If the maintenance message ECU, PS13 SNSR LINE or ECU, PS13 SNSR LINE* is not confirmed:
(a) No maintenance is required.

(2) If the maintenance message ECU, PS13 SNSR LINE or ECU, PS13 SNSR LINE* is not confirmed but is repetitive:
- do a check for leak or blocked PS13 line or loose fittings (Ref. AMM TASK 72-23-00-280-001).
(a) If nothing is found or if the fault continues:
- replace the ECU (4000KS) (Ref. AMM TASK 73-21-60-000-001) and (Ref. AMM TASK 73-21-60-400-001).
B. Do the test given in Para. 3.A.
(1) No additional maintenance action is required if the fault is not confirmed.
(2) Repeat the fault isolation procedure if the fault continues.
