Types of OBD Scanner

OBD scanners are essential tools for accessing and interpreting a vehicle's onboard diagnostics system. By connecting to the OBD port of a car, these scanners can read diagnostic trouble codes (DTCs), monitor real-time data, and provide insights into the vehicle's health. There are several types of OBD scanners, each designed to cater to specific needs and preferences.

• Handheld OBD-II scanners: Also known as portable OBD-II scanners, they are the most widely used type of OBD-II scanner. As the name suggests, they are small, handheld devices that can easily be carried around and used. These scanners are designed to connect to the OBD-II port of a vehicle and can read and clear DTCs. They may also display live data streams and perform emissions readiness tests. Basic functionality is typical, such as reading and clearing codes, making them a popular choice for DIY mechanics and small repair shops.
• Bluetooth OBD-II adapters: Bluetooth OBD-II scanners are designed to connect to the OBD-II port of a vehicle and communicate wirelessly with a smartphone or tablet through a Bluetooth connection. This allows users to access diagnostic information and control various vehicle functions using a dedicated mobile app. These adapters are usually small and plug directly into the OBD-II port, providing a convenient and wireless solution for vehicle diagnostics and monitoring.
• Professional-grade OBD-II scanners: Professional OBD-II scanners are designed specifically for automotive technicians and professionals. They are more advanced and have broader capabilities than handheld or Bluetooth scanners. For instance, they can access all vehicle systems, including ABS, air conditioning, and others. Professional-grade OBD-II scanners typically have larger screens, advanced diagnostic functions, and support for various automotive makes and models. Some can perform active tests, programming, and key coding.
• OBD-II safety scanners: These scanners are designed to ensure the safety and security of vehicles, especially those with advanced driver assistance systems (ADAS) and connected features. They diagnose and validate the proper functioning of safety-related components and systems, such as brakes, airbags, seat belts, and collision avoidance systems. OBD-II safety scanners can also perform calibration and alignment checks after maintenance, repair, or parts replacement to ensure the vehicle's safety systems function correctly and consistently.
• OEM-specific OBD-II scanners: These OBD-II scanners are developed by the vehicle manufacturer for use with their specific brand and model vehicles. They provide in-depth diagnostics, programming, and coding capabilities tailored to the vehicle's systems and components. OEM-specific OBD-II scanners can access proprietary data, perform advanced functions, and communicate seamlessly with the vehicle's modules, making them essential tools for authorized dealerships and specialized automotive repair shops.
