 A. If the fault symptom is identified by the CFDS message CHECK GCU 2 PIN B14A, B14B IDG 2 PIN B1, B2 WIRING and the upper ECAM DU warning GEN 2 FAULT:
 - do a check of the wiring between the GCU 2 pins B/14A, B/14B and the IDG 2 pins B/1 and B/2 (Ref. ASM 24-21/01).

 (1) If the wiring is not correct:

 - repair it.

 (2) If the wiring is correct:

 - do a check of the resistance of the IDG 2 MPU coil between pin B/1 and pin B/2 (17.5 Ohms plus or minus 3.5 Ohms at 25.C).
 (a) If the resistance is out of the specified limits:

 - replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. AMM TASK 24-21-51-400-040).

 (b) If the resistance is in the specified limits:

 - replace the GCU-2 (1XU2) (Ref. AMM TASK 24-22-34-000-001) and (Ref. AMM TASK 24-22-34-400-001).
 NOTE : Do not remove the GCU 2 before you do the other steps of
____
 the trouble shooting.

 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). R **ON A/C 401-499,
R A. If there is no connection of the IDG 2 after engine start:
R NOTE : After an automatic or manual disconnection of the IDG 2, do a GCU2

____ R reset at the first engine start. In this case, this trouble R shooting procedure is not applicable.
R (1) Replace the IDG (4000XU) (Ref. AMM TASK 24-21-51-000-040) and (Ref. R AMM TASK 24-21-51-400-040).
