- do a check for damage/contamination of electrical connector P19 of the FUEL CONTROL UNIT (8022KM)
(1) If the electrical connector P19 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 6 and pin 7 pin 8 and pin 9 of the FUEL CONTROL UNIT (8022KM)
(a) If the resistance value is not between 20 Ohms and 100 Ohms (pin 6 - 7) and/or not between 10 Ohms and 80 Ohms (pin 8 - 9).
- replace the FUEL CONTROL UNIT (8022KM) (Ref. AMM TASK 49-32-11-000-003) and (Ref. AMM TASK 49-32-11-400-003).
(b) If the resistance values are in the specified limits:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/H11,G7,F6 to the FUEL CONTROL UNIT (8022KM) P19/6,7,8 and the FUEL CONTROL UNIT (8022KM) P19/9 and GND (Ref. ASM 49-61/02).
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).

3. Fault Confirmation
__________________
A. Read-out of ECB Trouble-Shooting Data
(1) Put the APU MASTER SW to the ON position.
(2) Get access to the APU SHUTDOWN report.
(3) Push the '>' adjacent to LRU DATA:
- the MCDU menu shows
FUEL FLOW DISAGREES WITH COMMAND
(4) Start the APU and apply Bleed Air for 20 seconds, minimum (Ref. AMM TASK 49-00-00-860-008).

A. If an APU auto shutdown occurs during the APU operation and the APU SHUTDOWN report gives the maintenance message:
NO FLAME
FUEL CONTROL UNIT P19/APU FUEL SUPPLY
associated with Fault Code Number (FCN) 79
- do a check for damage/contamination of electrical connector P19 of the FUEL CONTROL UNIT (P19)
(1) If the electrical connector P19 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 6 and pin 7 of the FUEL CONTROL UNIT (P19).
