I am selling my 1996 Impala SS (LT1), I have an OBD-II code reader... does the 2006 CTS-V use the same Code Reader?? I just want to know if I need to keep it or not?

Mike and my soon to own 2006 InfraRed CTS-V!

All vehicles are now OBDII.

All vehicles are now OBDII.

Yep which is actually mandated by the federal government and not just something nice the auto manufacturers do for us. :)

Hmmm, where's the plug?

You may need a new code reader, although all cars 96 and up are OBD-II for 06 the V got a new style ECM that uses GMLAN for communication.
While it MAY BE compatible, it also may not.
Only one way to know, plug it in.
