(2) Get access to the APU SHUTDOWN report.
(3) Push the '>' adjacent to LRU DATA:
- the MCDU menu shows FLOW DIVIDER SOLENOID SHOWS CIRCUIT FAILURE
(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 ACCELERATION
FLOW DIVIDER SOL P13
associated with the Fault Code Number (FCN) 126
- do a check for damage/contamination of the electrical connector P13 of the FLOW-DIVIDER SOLENOID (P13)
(1) If the electrical connector P13 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector P13 is OK:
- use a multimeter to do a resistance check across pin 1 and pin 2 and pin 1 and pin 3 of the FLOW-DIVIDER SOLENOID (P13).
(a) If the resistance value are not between 10 Ohms and 80 Ohms (pin 1 to pin 2) and/or < 100 kOhms (pin 1 to pin 3):
- replace the FLOW-DIVIDER SOLENOID (P13) (Ref. AMM TASK 49-32-13-000-001) and (Ref. AMM TASK 49-32-13-400-001).
(b) If the resistance values are in the specified limits:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/11 to the FLOW-DIVIDER SOLENOID (P13) P13/1 and the FLOW-DIVIDER SOLENOID (P13) P13/2 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).
