Hi,

Was it only the traction control lamp, or did the ABS or brake lamp turn on as well? Also, the security light is interesting. If you have a different key, try it to see if the security lamp turns on.

What I feel we will need to do is have the computer scanned for diagnostic trouble codes. I say that because there are a few things that can cause the traction control light to turn on.

Here is a link that explains how the computer is scanned:

If you don't have a scanner and feel it is safe to drive to a parts store, most of them will do it free of charge. Once it's done, let me know what codes are found.

Take care and Happy Easter.
