I have a 2002 deville, for the last week i have had the service theft system light on coupled with traction control and a constant security system light. I have a 02 cadillac deville dhs and the service theft system is on and car will not start mechanic's assistant: Today i tried to start my car but was unable to due to the service theft system;
Will give it a try had a key made thinking maybe that was it but still. Conducting necessary tests after the reset, such as checking. Last week i got the recall notice for my deville.
Usually a simple reset is able to clear up most of the. To check/service the starter motor and solenoid you must remove the intake manifold. There may be something there. The most common overheating problem with the northstar engine is a blocked purge line.
If the alarm system is acting up in your cadillac deville then the first thing that you should do is try to reset the system. I tried to relearn the key but that did not work. How long have you had problems starting the vehicle? How do you cahnge the thermostat on 2002 cadillac deville.
I own a 2000 cadillac seville sts and every once in awhile a message comes on the dash telling me to (service the theft system) the next time i start the engine the message. It's dry (no coolant involved) so it's a 20 minute nuts/bolts/electrical connector job.
