Find Out How Easy It really is to Use an OBD2 Scan Tool
For those who have any familiarity with On-Board-Diagnostics or OBD2 you no doubt know it is a system that monitors your vehicle's performance and will let the driver are conscious of any problems via the 'Check Engine' light about the dashboard. All car, light truck and SUV manufacturers have been mandated to have this system set up in their vehicles since 1996. When problems with the vehicle's systems occur the on-board computer generates a code to let the driver diagnose the issue. This code can be read by connecting and car diagnostic software towards the vehicle's computer.



OBD2 scan tools are for sale to use by any vehicle owner and are available in a wide range of price and performance. Professional mechanics normally have access to modern-day readers. Whatever the type of code reader you will find the way it is used is really the same.

To begin with you will generally need a cable to hook up with a scanner or even a PC with OBD2 software. Most scanners are universal in that they will browse the most common codes, but some of them may only work with certain vehicles so ensure that the scanner you've is compatible with your automobile.
Always make sure that the vehicle's engine is powered down before connecting your reader.
Locate the OBD2 system connection plug. If the vehicle is compliant with OBD2 protocols it's going to have a female 16-pin connection plug typically nearby the center console about the driver's side. Different vehicles could have different locations like beneath the steering wheel, behind the ashtray, between the front seats or under the driver's seat. A fast check online should allow you to find the place for your particular vehicle when it isn't readily noticeable.
Look at the vehicle's connector plug to ensure that all the necessary pins exist. Most importantly how the #4 and #5 pin for grounding as well as the #16 pin for the battery power supply.
Connect your OBD2 scan tool to the vehicle's computer. Your cable with the 16-pin plug at one end should hook up to the female port on your own vehicle. Then connect the contrary end of one's cable for your scanner.
An alternative to a hand-held scanner is to connect to your personal computer that has OBD2 software attached to it. You may need a cable with all the 16-pin connector on a single end using a USB connector alternatively to hook up with your PC. Bluetooth connectors are also available for this application.
Once you are connected it may take a short interval of your time for the reader to initialize. Your scanner will look at the vehicle's computer to find out which protocol is required and the increase the risk for connection. The scanner will read the malfunction code saved in your vehicle's computer and display it on the watch's screen.
To interpret the code you might need to consult the service manual for your vehicle even though some scanners will provide information for basic codes. Some scanner manufacturers offer access to programs that will interpret the code and provide repair procedures according to that code.
