no substitute for good old-fashioned troubleshooting.
Once you have isolated and repaired the failed problem(s), you can
use your AutoScanner to clear the codes from the computer's memory.
This will also turn off your Malfunction Indicator Lamp (MIL), or Check
Engine Light, and may reset all Inspection/Maintenance (I/M) monitor
statuses to “Not Ready”.
The following Quick Start section will help you begin to use your OBD II
AutoScanner right away. Subsequent sections of this manual contain
more detailed information to help you get the most out of your scanner.

1.2 Quick Start
Connect the OBD II AutoScanner to the vehicle’s Data Link Connector
(DLC) which is normally located under the dash on the driver’s side.
Once the connection is made, the tool will turn on, boot, and then
display the Main Menu. If the display is hard to read, adjust the contrast
using the Tool Setup/Test function.
All AutoScanner functions can be performed with the Key On-Engine
Off (KOEO). The ERASE function cannot be done with the Key
On-Engine Running (KOER).
To retrieve Diagnostic Trouble Codes
(DTCs), press the READ key on the
AutoScanner. This function can be
performed with the KOEO or KOER.
If DTCs are present, they will appear on the display. Use the ▲ or ▼
keys to view the codes. The definition will continuously scroll to the left if
it is longer than the display (20 characters). To freeze the scrolling message,
press and hold the ENTER key. When done, press the BACK key to return
to the Main Menu.
CAUTION! Avoid Cooling Fan! It May Turn On During Test.
