- repair it.
(2) If the wiring is correct:
- replace the SENSOR-TDC AC,1 (Ref. AMM TASK 24-22-18-000-001) and (Ref. AMM TASK 24-22-18-400-001).
**ON A/C 063-099, 106-149, 153-199, 206-299, 301-399,
A. If the fault symptom is identified by the CFDS message CHECK IDG 1 1999VT WIRING and the upper ECAM DU warning GEN 1 FAULT:
- do a check for open circuit on any of the two parallel cables between respectively the IDG 1 pins T/1, then T/2 and T/3 and the module 30XN1 pins 1, 2, 3 (Ref. ASM 24-22/01).
(1) If the wiring is not correct:
- repair it.
(2) If the wiring is correct:
- replace the SENSOR-TDC AC,1 (Ref. AMM TASK 24-22-18-000-001) and (Ref. AMM TASK 24-22-18-400-001).

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 1 pushbutton switch (3XU1).
(3) Do the operational test of the GPCU (Ref. AMM TASK 24-41-00-740-002).
(4) Start the engine 1 (Ref. AMM TASK 71-00-00-710-003).

C. Do this test:
-------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
On the ECAM control panel: On the lower ECAM display unit:
- get the ELEC page. - the correct electrical parameters of GEN 1 are shown and AC 1 busbar is supplied by GEN 1.
5. Close-up
________
A. Put the aircraft back to its initial configuration.
(1) Stop the engine 1 (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).
