Using an OBDii Scan Tool Is Easy-Find Out How
If you know anything about On-Board-Diagnostics or OBDii then you know it is a method to monitor your vehicle's performance and will let the driver know of any problems via the 'Check Engine' light on the dashboard. All car, light truck and SUV manufacturers have been ordered to have this system installed in their vehicles since 1996.
When problems with the vehicle's systems occur the on-board computer generates a code to let the analyze the problem. This code can be read by connecting an OBDii scanner to the vehicle's computer.
OBD2 scan tools are available for use by any vehicle owner and can be found in a wide range of price and function. Professional mechanics usually have access to more sophisticated readers. Regardless of the type of code reader you have the way it is used is pretty much the same.
To begin with you will first need a cable that connects to a scanner or to a PC with OBD2 software Autel MaxiTPMS PAD. Most code readers are universal in that they will read the most common codes, but some of them may only work with certain vehicles so ensure that the scan tool you have is compatible with your vehicle.
Always ensure that the vehicle's engine is turned off before connecting your reader.
Next locate the OBDii system connection plug. If your vehicle is compliant with OBD2 protocols it will have a female 16-pin connection plug typically located near the center console on the driver's side. Different vehicles may have different locations like under the steering wheel, behind the ashtray, between the front seats or under the driver's seat. A quick check online should let you find the location for your particular vehicle if it isn't readily noticeable.
Check the vehicle's connector plug to ensure that all the necessary pins are present. Most importantly that the #4 and #5 pin for grounding and the #16 pin for the battery power supply.
A different approach is to connect to a PC that has OBD2 software installed on it. You will need a cable with the 16-pin connector on one end with a USB connection on the on the end to hook up to your PC x431 pro mini. Bluetooth connectors are also available for this application.
Once you are connected it may take a short interval of time for the reader to initialize. Your scanner will check the vehicle's computer to determine which protocol is needed and the make the connection. The scanner will read the malfunction code stored in your vehicle's computer and show it on the screen.
To understand the code you may have to look it up in the service manual for your vehicle although some scanners will provide information for basic codes. Some code reader manufacturers also provide access to programs that will interpret the code and provide repair procedures based on that code.
