TT4 and ABS light on
 

I recently had these idiot lights come on and I am wondering if anyone has had this happened and what do I need to repair and or replace this time lol

My Hummer is a 2001 H1 wagon Thanks.... Kyle

Yes.......I have a 2001 also. The lights do not initially come on but eventually do...but only sometimes.

What happened in your circumstance?

thanks!!

Haven't had the problem but seems like I heard it is expensive. Maybe Hummech can shed some light on this for you.
