An OBD2 scan tool is a device that is used to diagnose and interpret error codes displayed by the onboard computer system of a vehicle. These error codes are generated when there is a fault in any of the electronic components of the car. OBD2 stands for On-Board Diagnostics, and the second generation is used in all modern cars sold in the USA. There are several services offered by an OBD2 scan tool, which are detailed below.
 

Reading and Clearing Error Codes

One of the most basic functions of an OBD2 scan tool is to read and interpret the error codes generated by the vehicle's computer system. Once the scanner is connected to the OBD2 port, it can access the codes stored in the system's memory, including both active and pending codes, and display them on a screen. Additionally, the device can clear the codes from the system, reset the check engine light, and turn off any other warning lights that may have appeared on the dashboard.
 

Live Data Stream

In addition ...
... to error codes, OBD2 scan tools can also display live data streams from various sensors in real time. Some of the parameters that can be monitored include engine speed, coolant temperature, fuel system status, throttle position, oxygen sensor readings, and many more. This feature can be used to diagnose problems with the engine or other related systems quickly, making the repair process more efficient.
 

Vehicle Information

OBD2 scan tools can also provide valuable information about the vehicle, such as the VIN (Vehicle Identification Number), the calibration ID of the onboard computer system, and the model year. This information can be useful in determining the correct replacement parts or software updates required for the vehicle.
 

Smog Checks

OBD2 scan tools can also be used in some states to perform smog checks. The device can access the emissions-related codes stored in the vehicle's computer system and determine if the vehicle is emitting pollutants beyond acceptable limits. This feature can help car owners to maintain their vehicle's compliance with environmental regulations.
 

Advanced Diagnostics

Some OBD2 scan tools come with advanced diagnostic features that can help diagnose complex problems with the vehicle's systems, such as ABS (Anti-lock Braking System), SRS (Supplemental Restraint System), or Transmission. These functions may require specialised software, hardware, or cables, and are typically more expensive.
 
An OBD2 scan tool is a powerful device that can provide a wealth of information about a vehicle's electronic components.
