A. 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), 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 ACSC2(57HH):
