: CAN bus or not?

In the processing of selecting LEDs for the interior of my 2011 CTS, I was confused if Cdillac uses a CAN bus system or not. CAN bus bulbs supposedly have a resistor in them to avoid false signals to the computer control system, Using can bus LEDs in a non can bus system will not work as well. My dealer parts or service folks didn't;t seem to know for some reason.

Just got the answer form the dealer. The 2011 CTS DOES have a CAN bus system. THis should be at least put in the owner's manual to avoid service problems down the road.

Mostly everything made by GM since 2005 has been Can Bus by 2006 Everything was Can Bus by GM.
Some GM's started as early as 2003
