So the ABS light is on in my car and when it goes out the brakes grind. I had my car put in the shop to be checked out and 2 codes came up. the first was C0040 which is the right front wheel speed sensor malfunction. the other is C0236 which is the traction control system circuit. the guy said that there is most likely a problem with electric brake control module, and he gave me 2 numbers of other garages in the area that could fix it because this issue is beyond him and what equipment he has. I would like to know if there is anyway you could get me an estimation on how much it will cost to fix these issues, or even explain to me what might need to be done to fix it.
