Any one that can read ISO generic OBDII parameters.  I use software for a
laptop and Autotap interface.  It works on both my Subarus, my son's Honda,
and my sister's Chev.

I've got one I grabbed nearly on impulse from Wal Mart of all places
for $100--works fine.

I posted the model and make here in the past--search the archives if
interested. Innova something or other I think.

I still like the Auterra.  I have both the windows and the palm version.

Hi,
If you have a laptop, get a interface kit and OBD II scan software
(some are freeware some are commercial). Then you can do more than
reading/clearing trouble code. I use Proscan and ELM327 USB interface box.

I took our '97 Outback in for service at a mechanic I trust, who is happy to
talk details with me, last week. It needed stuff I would usually do (struts,
radiator) that I just have not had time for, we have a trip coming up.
I mentioned that I had read out OBD codes, none there. He asked what I used
to read them, then went on to say they just got a new and fancier reader and
it was finding all sorts of things their previous readers were not getting.
Now the new one was a multi-thousand-dollar complete system scanner, from GM
I think, not a generic OBD reader. But now I am concerned, I thought that
the codes were all supposed to be standardized. Naturally the system will
grow, e.g. the addition of the CAN codes, but presumably a fairly large
commercial firm like that already had something reading all of the
standardized things, and like mine able to read out code numbers even for
manufacturer-specific codes even if it did not know what a particular code
meant.
Can anybody enlighten us as to what the somewhat hidden things might be, and
whether any affordable readers might see them? He said they had checked out
a car with their previous machinery and seen no codes, then connected the
new reader and found ten! Based on our discussions in the past and how he
has been willing to be open with me, I don't think he was just trying to
make me feel like I need to bring the car in rather than do my own work, we
have a pretty good arrangement where I do the things I feel comfortable with
and go to him for things like alignment where I don't have the needed tools.
