Having problems with your 1997 Cadillac DeVille ?
Theft car system
\015 Started the car and a warning light came on 'theft car system, car may not restart.' we started it and engine worked, and turned it off. Is there something we need to do so this does not happen again?\015
Dear Hun~ It all has to do with the Vats system in your car. You can bypass it or get a new key or you might need a new ignition cylinder.
I have the same prob with my 97 caddy mine was because i pulled the pcm fuse out , when i put the fuse back in the message appeared i just need the comp reset the code
