i just had new rear pads and rotors installed. prior to this my tcs light was always on (since day 1; i bought it about a year ago). when i picked it up from the shop the tcs light was off. i tested the tcs button to see if the light would go on and off, it did. it's fixed :o)

...or not :.o(

this afternoon i was driving on the highway about 65 mph, when out of the blue i noticed that the light had popped back on (at the time there was a very light sprinkling of rain on and off). i pushed the tcs button but the light didn't go off.

unfortunately, when i bought the car, there was no owner's manual so now i feel like i'm stuck on stupid. i'm hoping that somebody can let me know what the heck is going on.

thank you in advance for any help that's offered!

 

Without the actual code, going to be pretty hard to "guess" what the issue is?
