following lights came on in the d? I have a 2004 Chevy Cavalier LS Sport and this morning when I started it the following lights came on in the dash: Service, Trac off, and ABS.

Please let me know if you know what the issue might be or have had this happen too?

Thanks in advance!
Jack thank you for your help!
 
This means that there is a fault with your ABS system. You still have brakes, they are just no longer ABS brakes. Your traction control sysyem is also disabled because it uses the ABS system to work.

Whenever the computer finds a fault with the ABS system it immediately shuts the system down for safety reasons. You wouldn't want the ABS system to be working on only 3 wheels for example. The moment the ABS kicked in it would send you into a spin.

Most times when this happens the computer senses a fault with a wheel speed sensor. These are integrated into the wheel bearings. Connecting a scan tool to the computer's diagnostic port will quickly reveal the fault. The better scan tools will do more than give the code that was stored. It will tell the mechanic exactly what is wrong.
