Types of OBDII Scanner

An OBDII scanner is a tool used to read and interpret the diagnostic information from a car's Onboard Diagnostic II (OBD II) system. This system monitors the performance of the vehicle's emission system and can alert mechanics and car owners about potential issues that may affect the vehicle's emission controls. There are several types of OBDII scanners, which include:

• Basic OBD2 scanners: These are handheld devices that connect to the OBD2 port of a vehicle to read and clear diagnostic trouble codes (DTCs). They are used to perform basic functions like code reading and code erasing.
• Advanced OBD2 scanners: These are more sophisticated than basic OBDII scanners. They have advanced features, including live data streaming, freeze frame data, and access to vehicle-specific systems. They can perform more in-depth diagnostics, such as reading and clearing codes from systems like ABS, airbags, and others.
• Bluetooth OBD2 scanners: Bluetooth OBD2 scanners are small devices that plug into the OBD2 port of a vehicle and connect to a smartphone or tablet via Bluetooth. They allow users to access the vehicle's diagnostic data using an app on their mobile device. Some are designed for specific functions, like monitoring engine performance, while others offer broader diagnostic capabilities.
• Professional OBD2 scanners: These are high-end diagnostic tools used by professional mechanics and automotive technicians. They offer comprehensive diagnostic capabilities, including access to all vehicle systems, advanced live data streaming, coding and programming functions, and special service functions like oil reset, DPF regeneration, etc. Professional OBD2 scanners are essential for workshops that need detailed diagnostics and troubleshooting capabilities.
• Key Programming OBD2 scanners: These scanners are used to program and synchronize keys within a vehicle's ECU. They are important tools for locksmiths and key-cutting shops. Some advanced OBD2 scanners come with key programming capabilities, while standalone key programmers are available for vehicles that require key reprogramming after replacement.
• OEM-specific OBD2 scanners: these are diagnostic tools designed for specific vehicle manufacturers. They provide access to proprietary diagnostic functions and modules that standard OBD2 scanners might not handle. OEM-specific OBD2 scanners are essential for dealerships and specialized workshops that work on specific vehicle brands.
• Multibrand OBD2 scanners: These diagnostic tools are designed to work with various vehicles from different manufacturers. They offer a balance between general and specific diagnostics, making them suitable for workshops dealing with multiple car brands. Multibrand OBD2 scanners typically include basic diagnostic functions and can be upgraded for more advanced capabilities.

Specification and maintenance of OBDII scanners

Various OBDII scanners have different specifications that enable them to perform different functions. Below are some of the general specifications that users should be aware of:

• Display

  Some OBDII scanners have a basic LCD, while others have a high-tech color display. The display screen shows the user what is going on in the car's computer. Advanced scanners have larger screens that are brighter and more colored to show more details.

• Buttons

  Automotive scanners have buttons that allow the user to interact with the car's computer. The buttons include a menu button that goes to the main screen, a back button that takes the user back to the previous screen, and an up, down, left, and right button that navigates through the options on the screen. Some scanners have a touch screen and may not have more buttons.

• Connection port

  The connection port is used to plug the scanner into the car. It allows the scanner to communicate with the car's computer system. It is located under the steering wheel. The connection port is sometimes referred to as the diagnostic link connector or DLC.

• Power source

  Some OBDII scanners get their power from the car when plugged into the connection port. Others are powered by batteries. More advanced scanners get their power from the electrical system of the car and have a backup battery.

• Vehicle communication interface

  The vehicle communication interface allows the scanner to communicate with the car's computer system. It enables the user to access different features and functions, such as reading and clearing codes, retrieving live data, and running diagnostic tests. The interface connects the scanner to the car's computer system. It allows for communication between the two devices.

• Software version

  Some OBDII scanners have a software version that is updated regularly. The software version controls what the scanner can do. Some scanners allow users to update the software version by downloading the latest version from the manufacturer's website. Others have a software version that is fixed and cannot be changed.

Maintaining an OBDII scanner is important to ensure it functions properly. Below are some of the maintenance requirements:

• Users should follow the manufacturer's instructions when maintaining their OBDII scanners.
• It is important to keep the scanner clean. Users should wipe it with a soft cloth regularly to remove any dirt or dust. Cleaning prevents dirt from getting into the buttons and damaging them.
• Users should check the cables and connectors of the OBDII scanner to ensure they are not damaged. If they notice any damage, they should replace them immediately. This ensures a stable connection between the scanner and the car's computer.
• Users should charge the battery of the OBDII scanner regularly. They should only use the charger provided by the manufacturer to prevent damage to the battery.
• It is important to store the OBDII scanner in a dry, clean place away from direct sunlight when not in use. This prevents damage to the scanner.
• Users should update the software of the OBDII scanner to ensure it has the latest features and improvements. The process of updating the software varies depending on the scanner being used.

How to Choose OBDII Scanner

Choosing the right OBD II scanner can be difficult, but it doesn't have to be. Keeping in mind the following factors will help make the decision easier:

• Understand scanning needs

  Consider the types of vehicles that need to be scanned and the issues that need to be addressed. For example, a car owner can use a basic scanner, while a mechanic needs a professional one.

• Check compatibility

  Ensure the scanner is compatible with different vehicles, especially those that are older or newer.

• Live data and freeze frame

  Get a scanner with live data and freeze-frame capabilities. It helps to view real-time data and capture moments of an error.

• Future-proofing

  Consider a scanner that can be updated online to remain compatible with future vehicles and technology.

• Ease of use

  Choose an easy-to-use scanner with a clear screen and intuitive buttons. Consider one with a color display for better visuals.

• Diagnostic depth

  Consider how deep the scanner can go into diagnostics. Some scanners are more comprehensive and can do more than others.

• Additional features

  Consider extra features like an OBD II leak detector, printing reports, or advanced data analysis. They offer more value.

• Budget

  Set a budget for the scanner. Prices vary, so find one that meets the needs without breaking the bank.
