You have to run your codes. My guess Is you have a bad wheel speed sensor or a bad harness. All thes lights indidicate an open on the abs circuit but if its intermitent its probably the harness.

 

Sounds like its the ground wire located under the airbox, bolted to the frame rail. I remember installing an aftermarket air box on my car years ago and that ground wire beside the PCM had to be bolted under the heatshielding for the filter. It wasnt bolted down tightly and hence the trac light came on, abs light, service traction, emergency brake. I would check to make sure that wire is not corroded and is secure to the frame. It would help to get it scanned also, as stated above just to diagnose it better, it could also be a bad ABS module. Good luck.
