A. If the APU TEST menu gives the maintenance message:
LOW OIL PRESS SW P14
associated with Fault Code Number (FCN) 98
- do a check for damage/contamination of electrical connector P14 of the LOW OIL PRESSURE SWITCH (P14)
(1) If the electriacl connector P14 is damaged/contaminated:
- do a repair/cleaning.
(2) If the electrical connector is OK:
- use a multimeter to do a resistance check across pin 1 and pin 2 of the LOW OIL PRESSURE SWITCH (P14)
(a) If the resistance value is > 10 Ohms:
- replace the LOW OIL PRESSURE SWITCH (P14) (Ref. AMM TASK 49-23-51-000-004) and (Ref. AMM TASK 49-23-51-400-004).
(b) If the resistance value is < 10 Ohms:
- do a check and repair of the aircraft wiring from the ECB (59KD) AB/C5 to LOW OIL PRESSURE SWITCH (P14) P14/1 and the LOW OIL PRESSURE SWITCH (P14) P14/2 to GND (Ref. ASM 49-61/02).

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