You should be able to get your actron updated for CAN communications.

Right, I ment to add that you dont need a module, but CAN communications compatability.

Also there is an update for the PCM to work better with aftermarket scanners.

hmm thats interesting....good info to know. Id think GM wouldnt care about compatibility as long as it works with a Tech 2/CANdi box....

From reading I believe (SoCalDieselTech's) posts among others, the Candi module can be a problem even at the dealers. Hopefully future updates will help.

I called Actron. If you have had it less than 90 days with receipt, they will update it for free of charge, but you must call them first. If over 90 days or no receipt, $60 and i believe he said 3 weeks, to get it done.

The Actron CP9125 I bought seems to work. Of course, I don't have any codes yet. But when I plug it in, it just says "No Codes", as opposed to reading an error. Does that mean it works?
