ABS/DSC Brake lights are on in my gauges and from what I researched every thread I saw reported that the owner did not have cruise control capabilities. I tried cleaning the streering angle sensor, and also tried cleaning the wheel speed sensors. My cruise control works, but I still have these lights on. The only difference is when I hit the M button, there are still only 6 bars for the shift speed, when normally hitting the M button I believe theres supposed to be 7.

Anyone have any suggestions on what to do to pinpoint the problem my car is having? I read somewhere that it could also be my battery going out but before I spend cash on that I was wondering what other possibilities it could be? Btw my battery is probably about 3 years old.

Thanks in advance!
