How to determine if a car has CAN interface? Anybody know if a 2007 Impala SS uses the CAN interface already?
My old version of autotap doesn't seem to communicate with it.

The car has only 300 miles on it and it is in limp mode (no 1st and 4th gear) already. I dropped it off a the dealer this morning. I would have like to have read the actual code that was set before the dealer clears it.

hptuners Standard($499) or pro mpvi($649)will allow you to scan enhanced GM parameters/read codes on any vehicle on its supported list http://www.hptuners.com/products/vcmsuite_vehicles.php free of charge including CAN vehicles and will usually scan generic parameters & dtc's on every other gm vehicle from 96+ with the exception of a small few with oddball pcm's. It will also gives you (4) pcm locked licenses with the option to upgrade to year/model licenses.

You should also look into EFILive. With the new interface, you can read your codes directly from the interface without ever having to hook up a laptop. Couple that with an advanced scan tool and powerful Tuning tool, it can't be beat for the price of $749.

Considering autotap wants $250 to upgrade to a model that supports CAN, I might as well get a tuner. We have 3 LSx now, the 00 TA, 04 Avalanche, and the 07 Impala SS.
I wanted to start playing with the TA this winter anyhow.
Do both EFI Live and HPTuners allow you to read/clear the codes in non-GM vehicles? My parents have a pair of Fords that I troubleshoot as well.

Forgot to mention, the Impala with 300 miles on the odometer popped the fuse for 1/4 shift solenoid already. I was a little unprepared to troubleshoot it being that I have had the car for only 4 days now. The dealer couldn't find a short.
Now knowing what the code was for, I checked the harness as well. It is tough to see how that harness would short out since most of runs along the plastic intake. Could it be a bad shift solenoid that is sticking? It was a 10 amp fuse.

From the EFILive website:
"Communications protocols: OBDI/ALDL; OBDII/VPW, OBDII/CAN; GM-LAN"
EFILive is a GM specific tool, however, with the introduction of the CAN protocal, all generic parameters should be the same across all manufactures.
Here's some more info on V2: http://www.efilive.com/overview_flash2.aspx
And here's a link to the forum: www.forum.efilive.com
