The Best Car Diagnostic Tool
All cars made after 1996 are required
to contain an onboard diagnostics (OBD) port. Diagnostic codes are sent through
the vehicle's computer and read by diagnostic tools plugged into the OBD port.
These tools are used by automotive technicians and automotive parts stores.
Parts stores will usually charge for such a service. Diagnostic tools are not
cheap but they are an investment that can save hundreds of dollars in
do-it-yourself vehicle repairs. They can also save money and headaches when
buying a used vehicle.
Car MD has some good features to
offer in the way of auto diagnostics. Trouble codes can be uploaded to a
personal computer through the Car MD website. This website reads the codes and
provides recommendations, lists of parts needed, and an estimated cost of labor
Car MD could be a shady used car
salesman's worst nightmare. It can be plugged into any vehicle that was made in
1996 or later. Run a diagnostic test on a used car before buying.
Prices are always subject to change
but right now the Car MD website is offering this product for around $100
Reports by the nonprofit agency
ConsumerReports.org reveal that while this tool does work as promised and is a
value at the price, consumers will get more out of similar but more expensive
diagnostic tools (ConsumerReports.org, 2007).
The Pocket Scan CP9125 made by Actron
is at present a bit more expensive than Car MD but according to
ConsumerReports.org it is a better diagnostic tool. Its superiority comes from
the fact that, in addition to running diagnostic tests and making the results
understandable for a novice, it is also capable of resetting the "check
engine" light. Car MD does not offer this feature. This tool is on the
smaller side which makes it easier to fit into place on some vehicles.
The Innova 3130 scan tool is at the
high end of the price scale. This is a volatile and fairly new business model,
so prices could change radically in the future, particularly given the current
car market, but the creator of this tool is currently selling it for around
$300 (Equus.com, 2009). One of the features that makes this device worth the
price is the all-in-one display screen. The manual is available for online
viewing prior to purchase and it comes with an instructional DVD. This unit can
be updated through a personal computer. 【From：www.obdtools.net】
