The car sometimes on starting gives message Service Theft System and codes are current VTD B 1009 & VTD B 2734. It does not happen every time. it is any anying message. Any idea what should I check. I believe there must be some security module. Are there any security sensors. If so, where are these located. Any ideas how to troubleshoot this problem

Thanks
John

I googled these codes and did not get any good info. Does anyone has any idea how security system works. Are there any modules or sensors installed in car. Any ideas please?

Thanks
John

There is a link to code definitions in the sticky thread on how to pull DTCs.

Yes, there are modules involved. In a nutshell - There's an RFID chip in the head of the key, and an "exciter" in the lock cylinder. If a key that hasn't been paired with the car is used, the starter and fuel pump are disabled.

go here for code definitions -
http://www.cadillacfaq.com/faq/answers/dtccode.html


ALWAYS include code definitions along with the code numbers -

no one has them all memorized -

and MOST viewers who don't see the definitions along with the codes
will simply bypass the thread -
