Anyone ever get a mesasge on the DIC saying:

Check Theft Control System

(I think thats what it said, I selected past the message without writing it down...)

Replaced the front tires yesterday and the tire shop said the alarm kept arming itself while it was on the hoist and going off. They thought someone in the shop had the keys and was messing with them...

hum, never heard of that one. Could be something wrong with your alarm then, if it kept going off and you got a message. Has it ever gone off by itself recently with you?

Stock GM alarm right?

yea, stock alarm...it'* kendras car so i dont drive it that much. Have to have her keep an eye on it. Once I selected past the message i havent gotten it back.

Service Theft System-34 Is the message displayed in the DIC. There may have been a momentary glitch in the Theft Deterrent System.
