(a) If there is no ECB related fault message:
- replace the INLET GUIDE VANE ACTUATOR P21 (Ref. AMM TASK 49-23-51-000-002) and (Ref. AMM TASK 49-23-51-400-002).
(b) If the fault continues:
- disconnect the connector P18 of the SURGE CTL VALVE (TORQUE MOTOR).
- do the operational test of the APU again and ignore SCV related fault messages.
