根据NW Steering fault 故障描述,前轮转弯失效不会导致BSCU(含刹车)完全失效。如果BSCU Fail,也会带来额外其他CAS信息,与FCOM不符。
需FMGC协助继续排查下。

According to the NW Steering fault description, a failure of nose wheel steering system does not result in a complete failure of the BSCU. A BSCU failure would also produce additional CAS information that would be inconsistent with the FCOM. Further investigation is required with the assistance of the FMGC.
