A. If the test gives the maintenance message TEST FAILED with the fault code (6E):
- do a check for a ground signal at the PC 2 (27HH) connector AA/9B (Ref. ASM 21-61/01).
(1) If there is no ground signal:
- do the BITE test of the landing gear (Ref. AMM TASK 32-69-00-740-001).
(2) If test gives a different maintenance message refer to the Fault Symptom List.
(a) If the fault continues:
- do a check and repair the wiring if necessary between: PC 2 (27HH) connector AA/9B and LGCIU 2 (5GA2) connector AB/3J (Ref. ASM 21-61/01).
(3) If the fault continues:
- do a check and repair the wiring between: PC 2 (27HH) connector AB/6B and FCV (8HB) connector A/D, PC 2 (27HH) connector AA/1D and FCV (8HB) connector A/E, PC 2 (27HH) connector AA/1C and FCV (8HB) connector A/F, PC 2 (27HH) connector AA/1B and FCV (8HB) connector A/G, PC 2 (27HH) connector AA/1A and FCV (8HB) connector A/V, PC 2 (27HH) connector AA/11C and FCV (8HB) connector A/J, PC 2 (27HH) connector AA/11B and FCV (8HB) connector A/K, PC 2 (27HH) connector AA/11A and FCV (8HB) connector A/L (Ref. ASM 21-51/01).
B. If the test gives the maintenance message P2 CONT:
- replace the CONTROLLER-PACK 2 TEMP (27HH) (Ref. AMM TASK 21-61-34-000-001) and (Ref. AMM TASK 21-61-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring if necessary between: PC 2 (27HH) connector AA/5A and CB (21HH), PC 2 (27HH) connector AA/5B and GND, PC 2 (27HH) connector AB/13D and CB (22HH),
