Under car scanner

Types of Under-Car Scanners

An under-car scanner, also known as a vehicle lift or car inspection scanner, is a device used by automotive technicians and mechanics to inspect cars. It is used during the vehicle inspection process to access the undercarriage of a car and check for damages or wear. There are several types of under-car scanners, each with unique features and capabilities. Here are some of them:

• OBD-II Scanners

  These are handheld devices that plug into the OBD-II port of a car, usually located beneath the dashboard. They read and clear diagnostic trouble codes (DTCs) and display real-time data from various sensors. OBD-II scanners are further classified into:

  - Basic OBD-II scanners: These devices read and clear codes and are used for emissions-related issues. They cannot access advanced data or perform special functions.

  - Professional OBD-II scanners: They are more advanced than basic OBD-II scanners. They access various vehicle systems, including ABS, SRS, and others, and perform special functions like actuator tests and key programming.

• Bluetooth OBD-II Adapters

  These are small devices that plug into the OBD-II port and connect wirelessly to a smartphone or tablet. They allow car data to be accessed using a compatible app, and some can read and clear codes, while others provide live data and advanced features.

• CAN Bus Scanners

  These are used to diagnose and communicate with the Controller Area Network (CAN) bus, a vital network in many modern vehicles. They are important for accessing systems beyond the OBD-II interface and integrating with other diagnostic tools and equipment.

• Under-car inspection systems

  This is a diagnostic tool that inspects and analyses a car's undercarriage. It provides a detailed report on the condition of various components, such as the exhaust system, suspension, and others. Some inspection scanners have advanced features like video inspection, allowing for a visual inspection of hard-to-reach areas.

• Handheld automotive scanners

  These are portable and easy to carry. They are used for reading and clearing codes and accessing various vehicle systems. Some handheld automotive scanners have advanced features like touch screens, built-in printers, and data logging capabilities.

• Vehicle diagnostic machines

  These are professional-grade tools used for comprehensive vehicle diagnostics. They can communicate with multiple vehicle systems, including engine, transmission, ABS, SRS, and others. Some have advanced features like programming capabilities, key coding, and module coding.
