A. If the fault symptom is identified by the CFDS message CHECK IDG 2 FEEDER PIN T1, T2, T3 SHORT TO GROUND and the upper ECAM DU warning GEN 2 FAULT:
- do a check of the aircraft wiring for short to ground between respectively the IDG 2 pins A/T1, B/T2, C/T3 and the GLC 2 pins D, E, F (Ref. ASM 24-22/01).
(1) If the wiring is not correct:
- repair it.

B. Do this operational test to make sure that the system operates correctly.
(1) Aircraft Maintenance Configuration
(a) Energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-861-002).
(b) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. AMM TASK 31-60-00-860-001).
(2) On the ELEC panel 35VU:
- push, release and push again the GEN 2 pushbutton switch (3XU2).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 2 (Ref. AMM TASK 71-00-00-710-003).
C. Do this test:

________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 2 (Ref. AMM TASK 71-00-00-710-028).
(2) On the ECAM control panel, set the UPPER DISPLAY and LOWER DISPLAY potentiometers to OFF.
(3) De-energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-862-002).
