So I installed led bulbs on my 8. All three of them. I had an extra one from the 2 pack for the third brake light. so i used it on the reverse light. I set the transmission to reverse without turning on the car, only to the on position. All the lights worked perfectly. I had the car off for about 3 days. Then when i went to use it, the TC and ABS lights came on. My car has 143k. Is that normal wear? It has not gone through any hard bumps or anything like that. I tried the turning the steering wheel. I did the pumping the brakes. I did the holding the odometer button when turning on. disconnected the battery. took it to pepboys and put on the scanner and nothing. Im thinking its the speed sensors. how do i make sure? Any advise is highly appreciated.

 

After you disconnect the battery, you have to calibrate the steering. Turn it all the way left, then all the way right (I think). Reboot the car and the light should be off.

 

i did not try that. all i did was turn the steering all the way left and right while the car was on. i do it while the battery is disconnected?

 

When you first reconnect the battery.

 

tried it and nothing

 

LED lights will cause the car to trip the TC/DSC lights if you didn't install a resistor, read up: DIY: LED 3rd Brake Light.
