Why a Scan Tool
Obtaining Trouble Codes »
the vehicle's computer is constantly
monitoring all aspects of vehicle operation. If a problem is detected, a trouble
code is saved into the vehicles computer memory. Some problems illuminate the
dashboard Check Engine light, others do not. Reading the error code can help
determine if a problem exists.
Save Money » a mechanic can charge $100 or more to read a single
trouble code - quite expensive. The Auterra Dyno-Scan scan tool saves money
allowing you to read and clear codes as many times as required.
Do-It-Yourself Vehicle Repair » the home mechanic needs a scan tool
to perform any type of vehicle maintenance. Accessing the trouble codes and extinguishing
the Check Engine light after repairs are made is essential. Vehicles with the
Check Engine light illuminated fail smog, even if you've repaired the problem
yourself and now would pass inspection.
Informed Consumer » not repairing the vehicle yourself? When the
Check Engine light illuminates, read the trouble code before taking the vehicle
in for repair. Being an informed consumer helps to prevent unnecessary repair
Purchasing a Used Car »
buying a used car is a gamble. Is the car
mechanically sound, or is it going to require expensive repairs? Auterra scan
tools read trouble codes from the vehicle's memory. Not all trouble
codes illuminate the dashboard Check Engine light so a scan tool is required.
The Dyno-Scan can be used to verify
if a used vehicle trouble code log is free of errors. This does not guarantee
the car is free from defects, its just one more indicator that you the consumer
can take into consideration.
VIN Switch Scam Protection » Every
vehicle made has a unique Vehicle Identification Number (VIN) plate located on the
dashboard that can be viewed through the windshield. VIN switching is a
technique used by thieves to disguise the identity of a stolen vehicle by
replacing the VIN number plate with a number from a non-stolen vehicle.
Fraudulent titles and registration papers are also created to complete the scam.
The unsuspecting customer then purchases the vehicle and tries to register it,
only to find out its stolen. Law enforcement takes the vehicle from the buyer,
returns it to the original owner, and the buyer loses the entire cost of the
vehicle. The thieves are so adept at counterfeiting, even used car dealerships
have been tricked into selling a stolen vehicle. To help protect yourself against
this scam, the Dyno-Scan reads the VIN number from the vehicle's on-board
emission control unit (ECU). The on-board ECU computer
VIN and the windshield VIN plate must match. If they do not match, find
another car to purchase as this vehicle VIN plate has been tampered with. This crime is on
the rise and avoiding it could save you tens of thousands of dollars.
Engine Tuning » Automobile enthusiasts
use our products to assist in obtaining the most performance possible from an
engine. Did that engine modification really make more horsepower? How fast is my
car in the 1/4 mile? The scan tool Record/Playback feature can also be used to record engine
sensors, such as ignition timing advance, as the vehicle travels down the drag strip. After the run,
performance data is reviewed and compared to previous runs or other vehicles.
Ignition timing advance in particular is useful for determining when the ECU's
knock retard is kicking in.
Preventative Maintenance » on every oil change a quick check of the
vehicle's trouble codes can head off costly repairs. It only takes a few
seconds. Only emission related errors cause the Check Engine light to
illuminate. Other vehicle problems, like automatic transmission malfunctions,
may only be detected by reading the trouble code. Finding problems before it
becomes serious can reduce costly repair bills.
Used Car Dealer » buying cars at used
car auto auctions to resell? Use our scanner to verify the vehicle is free of defects
before placing a bid on a vehicle. A vehicle that requires expensive repair is
not likely to be a wise business investment.
Aftermarket Installer »
install stereos, alarm systems, or performance components on vehicles? If you
accidentally trip the Check Engine light, don't go to the dealer. Read and clear
the fault code yourself saving time and money.

data logging capabilities.
