PC 2 (27HH) connector AB/14A and GND (Ref. ASM 21-61/01).
(2) If the fault continues:
- a check and repair if necessary the wiring of the signal: ARINC 429 XTR (P) from the ZC (8HK) to the PC 2 (27HH), ARINC 429 XTR (S) from the ZC (8HK) to the PC 2 (27HH), ARINC 429 RCV (S) from the ZC (8HK) to the PC 2 (27HH) (Ref. ASM 21-63/02).
(3) If the fault continues:
- do the trouble shooting procedures for the pack 2 electrical component with short circuit (Ref. TASK 21-61-00-810-821).
R **ON A/C 401-499,
A. If the test gives the maintenance message TEST FAILED with the fault code (6E):
- do a check for a ground signal at the ACSC1 (47HH)AA pin 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).
(a) If the test gives a different maintenance message, you can find the related trouble shooting procedure in the applicable Page Block 101.
(b) If the fault continues:
- do a check and repair the wiring (Ref. ASM 216101) from:
- the ACSC2 (57HH) to the LGCIU 2.
(2) If the fault continues:
- do a check and repair the wiring (Ref. ASM 2151S01) from:
- the ACSC2 (57HH) to the FCS (24HB).
B. If the test gives the maintenance message ACSC2 (57HH):
- replace the CONT-AIR COND SYSTEM 2 (57HH) (Ref. AMM TASK 21-61-34-000-002) and (Ref. AMM TASK 21-61-34-400-002).
(1) If the fault continues:
- do a check and repair the wiring (Ref. ASM 21-61/01) from:
- the ACSC2 (57HH) to the CB (53HH),
- the ACSC2 (57HH) to the CB (54HH) and,
- the ACSC2 (57HH) to ground.
(2) If the fault continues:
- do the trouble shooting procedures for the pack 2 electrical component with short circuit (Ref. TASK 21-61-00-810-821).
