tcs/abs light
So every so often over the past few months the tcs/abs light would come on while driving. After stopping and resuming drivingt, the lights would turn off. Now, every time I start the car and begin driving the tcs/abs lights come on within 1-4 minutes. I cleared the codes, drove the car and the only code the DIC displayed was TCS c1225h. I was wondering what this code meant and what is the first thing to check/possible issues? Thanks for any help!

The sensor is usually not the problem. It is almost always in the connectors or wiring. On mine the wire was broke inside the insulation at the connector coming out of the hub.

Its worth pulling the electrical connector to the sensor on the back of that hub. Give the connector a good clean and see if it improves.

Did you use a meter and check the resistance as the service manual suggests. Really easy to do, you don't even have to jack the car up. Those sensors are just a roll of wire so pretty much bulletproof. You have to replace the whole hub if you indeed have a bad sensor.
