    It should reset after a few days. That is what happened to me twice.

    You’ve seen the same message, but the problem may be quite different. Please see my reply in your thread.

    I booked my car Toyota Prius 2017 Business Edition as I was getting a sign Pre collision system malfunction (line assistant error) sign on my dash and I waited a very long time For An appointment then they kept the car for two days then they ring me and first they told me this car has no line assistance function in the vehicle ,the lane assistance button was located on steering wheel and they did not have a clue what they were doing ,then I was told this cars needs plenty of work for the car to be fully repaired and they told me I needed to spend a couple of thousands then the car would be fixed also they said the car needs the front radar front camera ECU to be changed, They said that if the car is involved in a crash then the sign comes permanently and cannot be removed and it’s a European law ,I bought my car home and I checked all fuses and I seen that one of fuse had blown therefore I changed the fuse everything was fixed without any cost ,these technicians don’t have no idea what they are doing and need to be educated ,and they charge extortionate prices and are a rip off However these technicians have no idea of hybrid vehicles :( very bad service please can you improve this ASAP as people are paying lots of money to repair with a dealer
