- ELEC DC BUS2 FAULT
and if, on the lower ECAM DU:
- the amber DC 2 indication comes into view
- the line between DC 2 and DC BAT buses goes out of view
- the DC ESS bus is supplied by the ESS TR: . replace the CNTOR-DC NORM BUS 2 SWITCHING (1PC2) (Ref. AMM TASK 24-35-55-000-001) and (Ref. AMM TASK 24-35-55-400-001).

Feb 01/02 CES (1) If the fault continues:
- do a check and repair the wiring between: . the circuit breaker (14PC) and the pin B/3 of the contactor (1PC2), through the contactors (5PU2, 1PC1, 4PC) . the pin B/5 of the contactor (1PC2) and the ground (Ref. ASM 24-35/02).
R C. Do the test given in para. 3.
