Re: check engine light

It's OBDII so stop at any major auto parts store and they will read it for free and clear (if its not a hard code). :thumbsup:

Re: check engine light

Let's move this to the proper forum..........

and your car has its own built-in code reader/scanner system. Use the sticky post just above this in the Deville forum - "How to pull codes". Study and use the proper year/car group for OBD-II. --------hang on ........

How can I reset my check engine light on my 2001 dts
------------------------
the check engine light only illuminates when there is a problem -
so - you don't want to simply shut it off -
you need to find out WHY the light came on -

and you don't need to take your car anywhere to read the codes -
you have a built-in scanner - so you can do it yourself -

to check for Diagnostic Trouble Codes -

if you don't know how -
go here and read the ENTIRE post -

http://www.cadillacforums.com/forums/cadillac-deville-1985-2005-including-1985/138257-how-pull-codes-dtcs.html

if you have any codes - post them here -
ALONG WITH THEIR DEFINITIONS -
