How to Use Actron

by Natasha Parks

Ohio-based Actron manufactures and sells vehicle scanning equipment. Actron's auto code scanner allows you to connect it to your home computer to diagnose a variety of problems with your vehicle. The scanner displays a series of fault codes identifying problems. As of November 2010, the scanners cost between $150 and $300, depending on whether you buy a basic model or upgraded Pro Scanner.

Connect the scanner to your vehicle. Locate the OBD II connector under the steering column, remove the cover, and turn the ignition to the "ON" position, but do not start the engine. Plug the OBD II connector into the vehicle connector.

Scan the required component. The tool automatically reads codes, and monitors and displays your vehicle's data. When this is complete, press the "BACK" key to return to the main screen.

Retrieve the list of diagnostic trouble codes (DTCs) and code definitions from the vehicle's computer. To read the data, press and hold the "READ" key for two seconds, then release it or select the "READ CODES" option from the main menu. If a DTC is reported, there is a potential malfunction in that part of the vehicle. Pending DTCs do not always indicate failure of the component. They show up when a non-persistent problem has been detected.

Erase codes from the vehicle computer by selecting the "ERASE" option. Confirm your choice by selecting "YES," or decline by selecting "NO." If a problem persists after erasing its code from the vehicle, the problem has not been fixed.

Freeze-frame live timing to pinpoint your vehicle's problem. Selecting this option from the menu allows you to display a snapshot of the operating conditions at the time the diagnosis was created.

Play back the timing to scrutinize the data and create a clear diagnosis. You can also find out about the emissions data by selecting "VIEW DATA." This gives details about switches, sensors, solenoids and relays.

Connect the device to the Internet or your home computer to record the results of scans and to download new scanning suites from the manufacturer.
