I'm going to buy a scanner and don't know which one of the zillion out
there to buy. I just mess with cars for fun and don't need an expensive
The fastest and easiest thing is to just go to the nearest Sears and
picking up their Actron OBDII scanner, which is reg.$129.99 and on sale
for $100 -- I presume that one is as good as any, for what I want it
Anyone know of a better one for the same price or less?

I have been following this thread and have a question: I clicked on
the above links and also looked up the Sears one the OP wanted, and I
noticed the inepensive one ($29) had the CAN feature while the $99 Sears
one did not.
What is CAN, and why would a much more expensive device not have it,
whereas the cheap one does?
CAN is an acronym for Controller Area Network. It's a communication
protocol used on many vehicles and industrial applications as well.
Developed by Bosch.
The unit Sears sell IS CAN compatible, all of the Actron units sold
after about 2008 have CAN built in.
Why do you need it? There are quite a few vehicles that use the CAN buss
for the various control modules to talk. Without it you will either get
the wrong information OR no information at all.
The problem now is that there are even more protocols in the line and
it's making things interesting. The good thing with many of the new
tools is that it is possible to update much of it in software.
All vehicles 2008 on are required by the EPA to be CAN protocol so any
scanner you buy should have CAN protocol.
The cheap units are just a code reader, not a scanner. If you want the
ability to look at sensors and diagnose problems you need a scanner not a
reader. Other features to consider is being able to keep a history of the
scans for reference. To do that you it will need PC attachment and software.
Look at some of the PC scanners for their features.
No such requirement. The only EPA requirement is that the vehicle must
have either OBD or OBDII interface functionality. Makers can use
whatever they like behind the interface as long as the port communicates
The CAN protocol is just another step in the line of communication
protocols. The original protocols cannot handle all of the information
and control modules that are on the newer vehicles.
You're looking at the Actron CP175 that Sears has on sale. Amazon has it for
$82.25 w/ free shipping.
But the question is - what features do you want? Do you just want to pull
generic codes from the powertrain for domestic cars? For foreign cars?? Do
you want enhanced codes too? Do you want the option to pull tranmission
codes? ABS codes? Airbag system codes?
Do you want to look at sensor values in real-time? You need to know this
before you buy a scanner.
Before buying ANY tool you need to ask yourself what do you want to do
with it. The 9175 you are looking at ONLY reads the GENERIC codes and
lets you clear them.
For that the cheap HF unit (98568) at 45 bucks would work.
........................ and don't let the MSRP prices scare you. The
retailers give hefty discounts.
MSRP on the 3120 is $340.87 but Amazon.com sells it for $144.14
