For those who do repairs what is your favorite scan tool? I am thinking
about purchasing an Actron cp9145 for $180.00

I use this one http://www.obd-2.com/#home on my laptop. It gives me the
ability to save the scans on the laptop for future reference. It also has
excellent support and constant updates.

I bought an Actron 9135 (I think it has less built-in info than the 9145)
because it was the least expensive device ($160) that looked like it met my
needs... at least when I needed it. I only use the reader occasionally, but
it sure is useful when I need it!

The code CD that comes with the reader seems useless, though. Their website
is more up-to-date and easier to use.

Seems to me that some smart person could make a OBD scanner adapter/SW
package to work with a Palm pilot or similar handheld PC. An inexpensive
adapter.

Do I understand this right: One downloads the appropriate software for
the car of interest?

If so, very slick!

Remco

Software I was impressed with from;
http://www.autotap.com/

Made for Palm OS machines or PC computers.

OBD-II is actually three separate protocols: ISO, VPW, and PMW. Your
car uses just one of these three. Inorder to be compliant to OBD-II
the device must be able to interface to each of the three protocols.

I suspect taht ISO, VPW, and PMW are lower layer protocols that are
just responsible for getting the "OBD-II content message" (i.e.,
trouble code X) transmitted from the vehicle to the reading device.
The code itself is universal across the three protocol (e.g., trouble
code 1011 (made up) means speed sensor malfunction over each of the
three protocols).


Many of the cheap PC versions of the interface require the user to
purchase a cheap interface card (under $100) that supports just one of
the three protocols. So it is technically not a certified OBD-II
device. Then there are an assortment of free and non-free programs
that you can use with the card.

Each manufacture has extended OBD-II interface and will have codes
that are unique to that manufacturer. I believe you can get access to
these online but if not the service manual should theoretically have
the codes.

OBD-II is quite limited in that there are just a few operations that
can be invoked. Examples include: a) fetch code, b) run a test c)
clear code.

Many (all?) manufactures have extended the interface to allow other
operations. One program allows you to send any command but you
basically have to figure out the binary representation of the command.
Theoretically this is dangerous because it is error prone and the
specs probably arent published.

I wonder if you can reload the firmware of the engine control module
this way?

I'd be surprised if any software can make the interface work without the
hardware, because the connector and voltage levels are not compatible with
any normal pc hardware. Usually the card does the hardware adaptation and
changes the message to a byte-oriented protocol the computer can deal with.

I opted for a stand-alone tool because I don't have a laptop or PDA handy
and I don't foresee the need for logging, etc.
