Jeep Liberty Esp Bas. My JK seems to hate me I come out of a movie the other night turn on the Jeep and the ESP/BAS as well as the ESP traction control warning lights came on and stayed on. You can use a good code scanner, or you can take it to the local parts store and see if they will scan it for you.
Asked in Jeep Jeep wrangler esp bas warning light? I'll be driving along and the cruise control will kick off, the ABS, EXP and "skidding car" lights will all come on. I cannot turn the light off manually and my manual says there is a problem if ESP BAS come on at the same time and to take it in.
BAS stands for brake assist control.
I thought it was odd but no big deal.
ESP on Jeeps and most newer vehicles stands for electronic stability program. ESP includes such functions as traction control, ESC (electronic stability control), and BAS. I'll be driving along and the cruise control will kick off, the ABS, EXP and "skidding car" lights will all come on.
