A car diagnostic tool can be an invaluable asset for any car owner, helping to identify potential problems before they become major expenses. In 2019, one of the leading solutions was Car Scanner ELM OBD2, a mobile application that leverages the power of OBD2 adapters to provide comprehensive vehicle diagnostics. This review delves into the features and functionality of Car Scanner, examining why it was considered a top contender for the best car diagnostic tool.
Car Scanner ELM OBD2: In-Depth Features
Car Scanner ELM OBD2 distinguishes itself through a rich suite of features designed to empower car owners with detailed insights into their vehicles’ performance and health.
Customizable Dashboard and Data Monitoring
The application allows users to personalize their dashboard with gauges and charts displaying real-time data, including engine RPM, speed, coolant temperature, and fuel consumption. This customizable interface allows users to prioritize the information most relevant to their needs. Beyond standard parameters, Car Scanner supports custom (extended PIDs), unlocking access to data often hidden by manufacturers. This feature provides a deeper understanding of your car’s inner workings. Figure 1 showcases an example of a customized dashboard displaying crucial engine parameters.
Diagnostic Trouble Codes (DTCs) and Freeze Frame Data
Like professional scan tools, Car Scanner can read and reset DTC fault codes, providing descriptions from a vast database. This allows users to understand the nature of potential issues and even clear minor faults. Furthermore, the application can access freeze-frame data – a snapshot of sensor readings at the moment a DTC is stored. This information is crucial for diagnosing intermittent problems and pinpointing the root cause of a fault.
Emission Readiness and Sensor Monitoring
Car Scanner enables users to check their vehicle’s readiness for emission tests, a vital feature for ensuring compliance with regulations. Additionally, the app provides a comprehensive overview of all sensor readings on a single screen, simplifying the process of identifying potential sensor malfunctions.
Vehicle Compatibility and Enhanced Profiles
While adhering to the OBD2 standard (applicable to most vehicles manufactured after 2000, and potentially some from 1996), Car Scanner boasts enhanced connection profiles for various car manufacturers. These profiles unlock additional features specifically tailored for Toyota, Mitsubishi, GM, Opel, Vauxhall, Chevrolet, Nissan, Infinity, Renault, Dacia, Hyundai, Kia, Mazda, Volkswagen, Audi, Skoda, Seat, BMW, and more. This ensures a more comprehensive diagnostic experience for a wider range of vehicles. Figure 2 illustrates the app’s compatibility with different car makes and models.
Additional Features: HUD, Acceleration Tests, and Trip Computer
Beyond core diagnostic functions, Car Scanner offers a Heads-Up Display (HUD) mode for projecting data onto the windshield, enhancing safety by keeping vital information within the driver’s line of sight. The app also includes a tool for precise acceleration measurements (0-60, 0-100, etc.) and functions as a trip computer, tracking fuel consumption statistics.
VAG Group Encoding
For vehicles from the Volkswagen Audi Group (VAG) built on MQB and PQ26 platforms, Car Scanner provides encoding functionality. This allows users to adjust hidden parameters within the car’s settings, potentially customizing features and unlocking hidden functionalities.
ELM327 Compatibility and Recommendations
Car Scanner requires a compatible Wi-Fi or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 adapter to connect to the vehicle’s diagnostic port. Recommended adapter brands include Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak. Users are cautioned against purchasing cheap, generic ELM327 adapters, particularly those marked as v2.1, as these are known to have compatibility issues and potential performance problems that could negatively impact vehicle operation.
Conclusion: A Powerful Diagnostic Solution
Car Scanner ELM OBD2 offered a compelling suite of features for car owners seeking a powerful and versatile diagnostic tool in 2019. From customizable dashboards and comprehensive DTC analysis to advanced features like HUD mode and VAG group encoding, it provided a valuable resource for understanding and maintaining vehicle health. While newer tools may have emerged, Car Scanner remains a testament to the potential of mobile-based diagnostics and its impact on car ownership.
