- put a jumper across the sockets 10 and 11 of the electrical connector P20 of the DMM on the APU harness side.
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/J2 to AB/J3; required value < 10 Ohms and the ECB (59KD) AB/C6 to structural ground; required value > 100 kOhms and the ECB (59KD) AB/C6 to AB/F11; required value > 100 kOhms, (Ref. ASM 49-61/01).
- put a jumper across the sockets 6 and 7 of the electrical connector P20 of the DMM on the APU harness side.
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/C6 to AB/F11; required value < 10 Ohms, (Ref. ASM 49-61/01).
(a) If the resistance values are out of the specified limits:
- replace DATA MEMORY MODULE (DMM) (8062KM) (Ref. AMM TASK 49-73-32-000-001) and (Ref. AMM TASK 49-73-32-400-001).
(b) If the resistance values are in the specified limits:
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
C. If the APU GND SCANNING menu gives the maintenance message:
DATA MEMORY MODULE (8062KM)
associated with Fault Code Number (FCN) 242 or 243
- do a check for damage/contamination of the electrical connector P20 of the DATA MEMORY MODULE (DMM)
(1) If the electrical connector P20 of the DMM is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector P20 of the DMM is OK:
- replace DATA MEMORY MODULE (DMM) (8062KM) (Ref. AMM TASK 49-73-32-000-001) and (Ref. AMM TASK 49-73-32-400-001).
(a) 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).
