How can an OBD2 Scanner help you?

OBD stands for 'On-Board Diagnostics.' This vehicle system monitors and reports on the performance of various components within a vehicle. These reports are intended to alert the driver or technician to any potential issues or malfunctions.


Global OBD scanner coverage is strictly related to emissions-related coverage. It is universal in that all vehicles sold in the US and Canada since 1996 must comply with this standard.


All ten modes of OBD-II are covered by Snap-on diagnostic tools and are accessed by selecting the OBD-II icon on the home screen.

Why is using a Car Diagnostic Tool important?

A car diagnostic tool interacts with a vehicle's on-board computer system to gather diagnostic information about the vehicle's health and performance. These tools can read fault codes, monitor sensor data, and conduct various tests to identify issues with the engine, transmission, emissions system, and other components, enabling the technician to diagnose and repair the problem.

What are the different types of Car Diagnostic Tools?

Code Readers: These are basic diagnostic tools that can only read and clear diagnostic trouble codes. They are typically more affordable than full-function OBD2 scanners and do not provide advanced diagnostic capabilities.


OBD2 Scanners: These handheld devices plug into the OBD2 port of a vehicle (usually located under the dashboard) to read diagnostic trouble codes (DTCs), view real-time data from sensors, and perform basic diagnostic functions.


Multimeters: Multimeter tools measure voltage, resistance, and other electrical parameters in a vehicle's electrical system. They are used to diagnose issues related to electrical components such as sensors, switches, and wiring.
