What is an OBD2 Scanner?

An OBD2 scanner is a diagnostic tool to access and interpret data from a vehicle’s onboard computer. This information helps technicians and vehicle owners diagnose and troubleshoot various problems in a car.

Purpose of OBD2 scanners

OBD2 scanners allow users to read diagnostic trouble codes (DTCs), clear the codes, and monitor real-time data. Using an OBD2 scanner lets vehicle owners identify issues early on, potentially saving time and money on repairs.

OBD2 vs. OBD1

OBD1 was the first generation of onboard diagnostic systems introduced in the 1980s. However, these systems needed more standardization and provided basic diagnostic capabilities. OBD2, introduced in the 1990s, offers a standardized procedure that works across most vehicle makes and models, providing enhanced diagnostic capabilities[^1^].

OBD2 Scanners for Electric Vehicles (EVs)

While traditional OBD2 scanners work well with internal combustion engine (ICE) vehicles, electric vehicles require specialized scanners due to their unique systems.

Differences between EVs and ICE vehicles

Electric vehicles have different powertrains, battery systems, and control modules than traditional ICE vehicles. This means that OBD2 scanners designed for ICE vehicles may not fully support EVs’ unique features and diagnostic requirements.

The need for specialized OBD2 scanners for EVs

As electric vehicles become more prevalent, the demand for diagnostic tools to effectively diagnose and troubleshoot EV-related issues has grown. Specialized OBD2 scanners for electric cars have been developed to meet this demand, offering advanced features and compatibility with EV-specific systems.
