A. If the test confirms the fault:
- do a check of the status of the C/B - APU GEN/EGIU2/115VAC (23XS).
(1) If it is open:
- close it.
(a) If it trips:
- do a check and repair the wiring between the pin AB/1D of the EGIU2 (22XU2) and the pin 9 of the module 29XN..

(b) If it does not trip:
- do a check for continuity of the wiring between the circuit breaker (23XS) and the pin 9 of the module 29XN. (Ref. ASM 24-23/01).
(2) If the fault continues:
- replace the EGIU-2 (22XU2).
