I was fiddlin' under the hood a couple days ago tryin' to wire up some neons.....when I finish and go to start my car, the TCS and ABS lights are both on and stay on. Anyone know whats wrong and what to do to fix this? TIA

 

Try disconnecting the battery and wait a few moments. After you reconnect your power your CPU will reset. See if that works, but before you try this you better find your radio and Navi codes for reprogramming them. (if you have a Navi)

 

Thats the same thing that happened to mine like a while ago, have you been driving your car or leaving it? it turns on and off the when you push the tcs it doesn't work but when i started to drive it again because i was doing my system it turn off like after 3- 4 days i tryed disconnting the batt too still nope and i was bout to bring it to the dealer then it just turn off.

 

I'm driving the car everyday..... So no one knows why it's on or how to fix really? I don't think disconnecting the battery will work huh? and it's been more than 3-4 days....
