Cadillac Repair Questions? Ask a Mechanic for Answers ASAP
Let's see if we can get your STS going again:
Do the brake lights illuminate?
Do you get the push brake message if you try to start without the brake on?
Do you have a scan tool to check for engine codes/communication problems?
And you had full communication with all modules using the Tech 2 right?
Was the vehicle running fine and all of the sudden it won't start or did it die on you at some point?
