(2) If the fault continues:

 - make sure that there is 28VDC at the pin 9 of the connector 1KS2-AC (Ref. ASM 73-25/05).
 (a) If there is no 28VDC:

 - do a check and repair the wiring between the circuit breaker 4KS2 and the EIU 2 (1KS2).

 (b) If there is 28VDC:

 - do a check and repair the wiring between the pin 2 of the connector 1KS2-AC and the pin 13 of the connector 4000KS-J2.

 (3) If the fault continues:

 - replace the EIU-2 (1KS2), (Ref. AMM TASK 73-25-34-000-040) and (Ref. AMM TASK 73-25-34-400-040).
