Hi. I checked the EBD fault readout with my ( cheap) reader. There was nothing shown. Ireset it just in case!. The fault was still r
there. I then disconnected the battery for approx. 24 hours, & replaced the battery in the key, as I believe that the key "talks" to the nats system, although the battery checked out ok. After reconnecting the batter the fault seemed to clear, & has not returned. Not teaching you to suck eggs, if you lock up the car before you disconnect the battery you cannot unlock the doors without the battery being connected. I hope this helps.
As an aside, iI believe that this fault appears if the steering column is changed befoe the battery is disconnected.
