(a)
If the fault continues:
-do a check and repair the wiring between pin A/3 of the fan air valve and the ground terminal.
(b)
If the fault continues:
-replace the VALVE-FAN AIR, ENG2 (9HA2) (Ref. AMM TASK 36-11-54-000-001) and (Ref. AMM TASK 36-11-54-400-001).

A. If the fault symptom is identified by the maintenance message: THRM 7170HM2 OR FAN AIR VALVE 9HA2 OR SENSE LINE:
-do a check of the indication of the bleed temperature on the lower ECAM display unit.
(1)
If the indication of the bleed temperature is more than 218 deg.C
(424.40 deg.F):
-make sure that there are no leaks at the sense line between the fan air valve control thermostat (7170HM2) and the fan air valve (9HA2).
(a) If the fault continues:
-replace the THERMOSTAT-FAN AIR VALVE CTL (7170HM2) (Ref. AMM TASK 36-11-43-000-001) and (Ref. AMM TASK 36-11-43-400-001).
(2)
If the fault continues:
-do a check of the wiring (Ref. ASM 36-11/02) between: . pin A/1 of the engine 2 fan air valve (9HA2) and pin AA/12A of the BMC2 (1HA2) . pin A/3 of the engine 2 fan air valve and the ground.
(a)
If the wiring is not correct:
-repair the wiring.
(b)
If the wiring is correct:
-replace the VALVE-FAN AIR, ENG2 (9HA2) (Ref. AMM TASK 36-11-54-000-001) and (Ref. AMM TASK 36-11-54-400-001).
