B. If the APU GND SCANNING menu gives the maintenance message:
SPEED SENSOR P26
associated with Fault Code Number (FCN) 9 or 10
- do a check for damage/contamination of the electrical connector P26 of the SPEED SENSORS 1 / 2.
(1) If the electrical connector of the SPEED SENSORS 1 and/or 2 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector are OK:
- use a multimeter to do a resistance check of the electrical connector P26 across pin 1/pin 2 and pin 5 for the SPEED SENSOR 1 and pin 3/pin 4 and pin 5 for the SPEED SENSOR 2.
(a) If the resistance is < 100 kOhms:
- replace the SPEED SENSOR 1 and/or 2 (Ref. AMM TASK 49-71-13-000-003) and (Ref. AMM TASK 49-71-13-400-003).
(b) If the resistance is OK:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/E6,E7 to the electrical connector P26/1,2 (SPEED SENSOR 1) and the ECB (59KD) AB/D3,D4 to the electrical connector P26/3,4 (SPEED SENSOR 2) (Ref. ASM 49-61/01).

_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).

associated with Fault Code Number (FCN) 7 or 8
- do a check for damage/contamination of the electrical connector P26 of the SPEED SENSOR (8060KM)
(1) If the electrical connector of the SPEED SENSORS 1 and/or 2 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector are OK:
- use a multimeter to do a resistance check of the electrical connector across pin 1 and pin 2 for the SPEED SENSOR 1 and pin 3 and pin 4 for the SPEED SENSOR 2.
(a) If the resistance is > 25 Ohms:
- replace the SPEED SENSOR (8060KM) (Ref. AMM TASK 49-71-13-000-003) and (Ref. AMM TASK 49-71-13-400-003).
