Guys. I took the car to the mechanic and he found an error code. He said sas receive no power, it might be sas is bad or there are a misconnection somewhere. He checked for a misconnection, checked the fuses underneath glove box and he comes to a conclusion. no misconnection in the wires, it seems the sas is bad. Well. I can't give up and let him to replace it and gain hundereds of dollars. I'll take the car to another mechanic, may be there are a simple solution not related to sas replacement. He tried the lock to lock procedures too with no result
