In 2015, finding a reliable and feature-rich OBD2 app for iPhone could be challenging. This article reviews Car Scanner ELM OBD2, a popular option at that time, highlighting its capabilities and limitations for users seeking a comprehensive diagnostic tool.
Car Scanner ELM OBD2: A Comprehensive Diagnostic Solution
Car Scanner ELM OBD2 aimed to provide a comprehensive suite of features for vehicle diagnostics using a Wi-Fi or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 adapter. The app boasted a customizable dashboard, allowing users to select specific gauges and charts for real-time vehicle data monitoring. Beyond basic diagnostics, it offered unique functionalities such as custom (extended PIDs) for accessing manufacturer-hidden data, Mode 06 for ECU self-monitoring test results, and emission test readiness checks.
One of Car Scanner’s standout features was its extensive DTC (Diagnostic Trouble Code) database, aiding users in understanding and resolving fault codes. The app also offered free-frames data (sensor states when a DTC is saved), offering deeper insights into potential issues. Performance measurement tools, including acceleration tests (0-60, 0-100, etc.), and trip computer functionality with fuel consumption statistics added further value.
Specific functionalities were available for certain vehicle makes and models. For VAG group cars (Volkswagen, Audi, Skoda, Seat) built on the MQB and PQ26 platforms, Car Scanner offered encoding features to adjust hidden parameters. A HUD (Heads-Up Display) mode projected data onto the windshield, enhancing the driving experience.
Adapter Compatibility and Considerations
Car Scanner ELM OBD2 required a compatible ELM327 adapter. Recommended brands included Kiwi 3, Viecar, V-Gate, Carista, LELink, and Veepeak. The app cautioned against using cheap, clone adapters often found on eBay or Amazon, particularly those marked as v2.1 due to potential bugs and connectivity issues. These could lead to unstable engine performance, connection drops, and increased data lag.
Important Disclaimer and Support
The app developers emphasized that the amount of sensor data supported varied across vehicle ECUs. The app could only display information provided by the car’s system. Importantly, the developers disclaimed any responsibility for incidents arising from the use or interpretation of the data within the application. User support was available via email or through the in-app “Contact Developer” option in the settings.
Conclusion
Car Scanner ELM OBD2 presented a comprehensive solution for iPhone users seeking advanced vehicle diagnostics in 2015. While reliant on a compatible ELM327 adapter and subject to the limitations of the vehicle’s ECU, the app offered a wide range of features, from basic fault code reading to customized data monitoring and performance testing. The caution against using cheap, unreliable adapters highlighted the importance of choosing quality hardware for accurate and stable performance.
