What is OBDII, OBD-II scan tool and OBD scanner software?
OBD is a computer-based system built into most modern automobiles which monitors emission related controls, performance of the engine, and detects malfunctions. OBD-II systems provide access to the health information of a vehicle and access to numerous data from the Engine Control Unit. The system offers valuable information when troubleshooting problems, including diagnostic trouble codes and various real time parameters, for instance.
OBD-II scan tool is a device that is used for communicating with a vehicle's OBD system and accessing the OBD information. A scan tool can be either a stand alone hand-held device, or it can be a small device attached to a vehicle accompanied with feature rich PC based OBD diagnostic software. The PC-based approach provides several benefits over the handheld, and with it, it is the software that brings the value. That's why we created OBDAutoDoctor.
How do I know whether my vehicle is OBD II compliant?
As a general guideline, your vehicle is most likely to be OBDII compliant if it fulfills one of the requirements listed below:
- USA: All cars and light trucks manufactured since 1996
- EU, Gasoline (positive-ignition engine): Registered in the EU after 1 January 2001 (EOBD)
- EU, Diesel (compression-ignition engine): Registered in the EU after 1 January 2004 (EOBD)
- Japan: All vehicles since 2004 (JOBD)
For vehicles that don't belong to any of those groups, refer to the vehicle's owner's manual for the compatibility info.
How does the OBDAutoDoctor diagnostic software work?
To start communicating with your car, you need to have ELM327-based scantool interface and a OBDII compliant car. Just connect the OBDII code reader to the physical 16-pin OBD connector plug located near the dashboard (typically below the streering wheel), lauch the scan tool software, and you are ready to go. The connection between the interface and the software can use bluetooth, WiFi, serial port or USB connection depending on the type of hardware you have.
Why do I need OBD software?
Are you tired of spending a lot of money on expensive dealer visits? Guess what? OBDAutoDoctor can reduce the amount significantly. By identifying the minor problems before they become major problems can save you a lot of trouble. For example, by diagnosing a rather low-cost repair such as the replacement of malfunctioning oxygen sensor, OBDAutoDoctor can save you the cost of replacing the expensive catalytic converter later.
You can also save time and money by making sure your vehicle is ready for emissions testing before taking your car to the inspection. By using OBDautoDoctor you can determine if your vehicle is ready for the tests. You can save even more if you are DIY mechanic. Just use OBDAutoDoctor to identify the problems, and do the repairs yourself. For example, by replacing an easy-to-change mass air flow sensor in 15 minutes yourself can save you as much as $200.
