- do a check for damage/contamination of electrical connector P12 of the LOAD CONTROL VALVE (8050KM).
(1) If the electrical connector P12 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- replace the LOAD CONTROL VLV (8050KM) (Ref. AMM TASK 49-51-51-000-004) and (Ref. AMM TASK 49-51-51-400-004).
(a) If the fault continues:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/F10,D7,D14 to the LOAD CONTROL VALVE (8050KM) P12/1,3,4 the LOAD CONTROL VALVE (8050KM) P12/2 to GND (Ref. ASM 49-61/01).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).

__________________
A. Read-out of ECB Trouble-Shooting Data
(1) Put the APU MASTER SW to the ON position.
(2) Get access to the APU LAST LEG/PREVIOUS LEG report.
(3) Push the '>'-key adjacent to the related CFDS failure message.
(4) If the MCDU menu shows:
APU AVAILABLE SHOWS CIRCUIT FAILURE
- do the Fault Confirmation that follows:
(a) Get access to the APU GND SCANNING menu.

201-210, Config-1 Aug 01/05 CES 4. Fault Isolation
_______________
A. If the APU GND SCANNING menu gives the maintenance message:
WRG: APU AVAILABLE
associated with Fault Code Number (FCN) 130
- do the Operational Test of the Annunciator Light Test System in the Cockpit (Ref. AMM TASK 33-14-00-710-001).
(1) If the AVAIL/ON annunciator lights on the APU START P/B (2KA) on the panel 25VU do not come ON:
- replace the ANNUNCIATOR-LIGHT TEST AND INTERFACE-BOARD (7LP) (Ref. AMM TASK 33-14-33-000-001) and (Ref. AMM TASK 33-14-33-400-001).
(a) If the fault continues:
- replace the APU START P/B (2KA).
(2) If AVAIL/ON annunciator lights on the APU START P/B (2KA) come ON:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J6 to the RELAY-APU AVAIL (6KD) A/X1 and the RELAY-ANNUNCIATOR-LIGHT TEST AND INTERFACE-BOARD (7LP) A/21 (Ref. ASM 49-61/01).
(3) If the fault continues:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
B. Do the test given in para. 3.
