R **ON A/C 401-499,
R A. If the test does not confirm the fault:
R (1) Do the reset procedure for the ACSC1 as follows,
R - open the circuit breakers 49HH, 50HH, 51HH and 52HH.
R - wait for a minimum of 5 seconds.
R - close the circuit breakers 49HH, 50HH, 51HH and 52HH.
R (2) No further trouble shooting is necessary.
**ON A/C 151-199,
R B. If on the ECAM COND page the CKPT trim air valve position indication shows amber XX:
- replace the TRIM VALVE CKPT (11HK) (Ref. AMM TASK 21-63-51-000-001) and (Ref. AMM TASK 21-63-51-400-001).
