warning lights
 

ok so i have some warning lights that keep coming on and off they are the ABS light and the STC light i have brought it to a mechanic and he didnt have a volvo code reader and he said that one might be causing the other cuz they are wired together. now what could the real issue be here and is it going to cost alot.

thanks for any input.
