I have a 97 SH and as I was getting on the interstate I went to set the cruise and the check engine light came on and about 3 seconds later the ATTS light came on. If it was just an ATTS problem would the CEL come on as well or is that going to be somthing different? And next question does anyone have any idea what a dealer charges to hook it up to read it?
thanx

 

Disregard think we got it worked out

 

hey can you tell me what happened becasue the same thing just happened to mine too, and i just bought the car. is it serious or just something simple?

 

Hey, I have a '99 SH, and I had the same question a while ago. What I found out is that apparently if your CEL comes on, your ATTS light comes on automatically as well. So even if your ATTS is fine, both panel lights come on. All I can think of is to get the whole thing checked out, which kinda sucks...

 

yeah i found out that it is my number 1 oxygen sensor, i'm gonna fix that and then hopefully the ATTS light will go off
