- do a check for damage/contamination of electrical connector P18 of the SURGE CONTROL VALVE (8058KM)
(1) If the electriacl connector P18 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 4 and pin 5 pin 1 and pin 2 pin 7 and pin 8 of the SURGE CONTROL VALVE (8058KM).
(a) If the resistance are not between 20 Ohms and 100 Ohms (pin 4-5/pin 1-2) or between 10 Ohms and 80 Ohms (pin 7-8)
- replace the SURGE CONTROL VALVE (8058KM) (Ref. AMM TASK 49-51-52-000-003) and (Ref. AMM TASK 49-51-52-400-003).
(b) If the resistance values are correct:
- do a check/repair of the aircraft wiring between ECB (59KD) 59KD-AB/D2,J8,D9,J7,G9,G6 and SURGE CONTROL VALVE (8058KM) P18/1,2,4,5,7,8 (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).
B. If the APU GND SCANNING menu gives the maintenance message:
SURGE CONTROL VALVE (8058KM) / ECB (59KD)
associated with Fault Code Number (FCN) 84
- do a check for damage/contamination of electrical connector P18 of the SURGE CONTROL VALVE (8058KM)
(1) If the electriacl connector P18 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 4 and pin 5 pin 1 and pin 2 pin 3 and pin 2 of the SURGE CONTROL VALVE (8058KM).
(a) If the resistance are not
between 20 Ohms and 100 Ohms
- replace the SURGE CONTROL VALVE (8058KM) (Ref. AMM TASK 49-51-52-000-003) and (Ref. AMM TASK 49-51-52-400-003).
