abs system on 2006 Buick Terraza

what does it mean when traction system and abs light comes on

Asked by for the 2006 Buick Terraza
when the abs fails, the trac fails too and the light will go on. when you have the abs repaired, the trac light will go off.

you need a shop to pull the abs code and have them diag the code to find the failed part.
