    If you have any knowledge of On-Board-Diagnostics or OBD2 you no doubt know it is a system that monitors your vehicle’s performance and can let the driver know of any problems via the ‘Check Engine’ light on the dashboard. All car, light truck and SUV manufacturers happen to be mandated to have this system placed in their vehicles since 1996. When issues with the vehicle’s systems occur the on-board computer generates a code to allow the driver diagnose the issue. This code could be read by connecting and obd2 diagnostic tool for the vehicle’s computer.

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

    To start with you will generally have to have a cable to hook up with a scanner or a PC with OBD2 software. Most scanners are universal because they will read the most common codes, but some of them may work with certain vehicles so be sure that the scanner you have is compatible with your automobile.

    Always make sure that the vehicle’s engine is turned off before connecting your reader.

    Locate the OBD2 system connection plug. If the vehicle is compliant with OBD2 protocols it’ll have a female 16-pin connection plug typically near the center console about the driver’s side. Different vehicles might have different locations like underneath the steering wheel, behind the ashtray, between your front seats or underneath the driver’s seat. A simple check online should let you find the area for your particular vehicle whether it isn’t readily noticeable.

    Look at the vehicle’s connector plug to ensure all the necessary pins are present. Most importantly the #4 and #5 pin for grounding and the #16 pin for your 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 vehicle. Then connect the contrary end of the cable in your scanner.

    An alternative to a hand-held scanner is always to connect to your personal computer that has OBD2 software installed on it. You will need a cable with the 16-pin connector on one end having a USB connector on the other to hook up with your PC. Bluetooth connectors are offered also for this application.

    Once you are connected it could take a short interval of energy for the reader to initialize. Your scanner will look into the vehicle’s computer to find out which protocol is necessary and the increase the risk for connection. The scanner will see the malfunction code stored 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 the vehicle even though some scanners will provide information for basic codes. Some scanner manufacturers provide access to programs that will interpret the code and offer repair procedures based on that code.
