Automatic handbrake problem

[mawallace]

So tonight I stopped at a set of traffic lights. It was on a hill. When I went to pull the auto hold released too early so the car rolled backwards. Put brake on again and tried again. After a few more unsuccessful attempts I had to turn auto hold off and operate brake manually

Ten minutes later warning light comes on dashboard and display. Warning triangle, centre display said

Error Auto hold
ACC and front assist not working
Fault Electronic handbrake

Went back to car later on and all is now fine.

Anyone know what happened
