 A. Test
 (1) Do the operational test of the probe ice protection (Ref. AMM TASK 30-31-00-710-001).
 4. Fault Isolation
_______________
 A. If the test gives the maintenance message CHECK ADIRU2 TAT PHC2 INTERFACE:
 - do a check for ground at pin A/<A of the PHC 2 (6DA2) (Ref. ASM 30-31/02).
 (1) If there is no ground:
 - replace the PHC-2 (6DA2), (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
 (a) If the fault continues:
 - do a check and repair the wiring from the PHC 2 (6DA2) to the ADIRU 2 (1FP2) pin A/<A to pin AA/4F (Ref. ASM 34-13/02).

 (b) If the fault continues:
 - do the INTERFACE TEST of the ADR (system 2) (Ref. AMM TASK 34-13-00-740-002)

 - do the necessary corrective actions: (Ref. TASK 34-13-00-810-910).

 B. Do the operational test given in Para. 3.

_______________
 A. If the test gives the maintenance message CHECK ADIRU3 PITOT PHC3 INTERFACE:
 - do a check for ground at pin A/<B of the PHC 3 (6DA3) (Ref. ASM 30-31/03).
 (1) If there is no ground:
 - replace the PHC-3 (6DA3), (Ref. AMM TASK 30-31-34-000-002) and (Ref. AMM TASK 30-31-34-400-002).
 (a) If the fault continues:

 - do a check and repair the wiring from the PHC 3 (6DA3) to the ADIRU 3 (1FP3) pin A/<B to pin AA/4J (Ref. ASM 34-13/02).

 (b) If the fault continues:

 - do the INTERFACE TEST of the ADR (system 3) (Ref. AMM TASK 34-13-00-740-002)

 - do the necessary corrective actions: (TSM chapter 34).
