Car Scanner ELM OBD2

Car Scanner ELM OBD2 is an app designed to provide comprehensive diagnostic, performance, and trip computer functionalities for your vehicle. By connecting to your car’s OBD2 engine management unit (ECU) via an OBD II Wi-Fi or Bluetooth adapter, the app allows you to monitor various aspects of your car’s operation in real-time. It enables users to view live sensor data, retrieve and clear diagnostic trouble codes (DTCs), and even customize the display of information through a personalized dashboard, making it a versatile tool for understanding your vehicle’s status.

Vehicle Diagnostics and Monitoring

The app serves as a robust diagnostic tool, allowing users to see what their car is doing in real-time by displaying live sensor data. It can read and reset Diagnostic Trouble Codes (DTCs), providing access to a large database of DTC descriptions to help understand the issues. When a fault code is saved, Car Scanner ELM OBD2 can read freeze frames, which capture the state of various sensors at the moment the DTC occurred. Additionally, the app supports Mode 06, offering access to ECU self-monitoring test results, which can aid in troubleshooting. For emission compliance, it can check if your car is ready for emission tests, and it provides a single screen to view the status of all sensors.

Customization and Extended Data Access

A key feature of Car Scanner ELM OBD2 is its ability to let users create a custom dashboard. You can arrange the gauges and charts you want to see, tailoring the interface to your specific needs. The app also supports adding custom (extended PIDs), which can reveal information that car manufacturers might not typically make visible. Furthermore, it includes numerous connection profiles for specific car brands such as Toyota, Mitsubishi, GM, Volkswagen, Audi, and others, potentially unlocking additional features and data relevant to those vehicles. The dashboard also offers a HUD mode, allowing you to project data onto your car’s windshield.

Performance Measurement and Trip Computer

Beyond diagnostics, the app provides tools for measuring vehicle performance. It includes a feature for accurate acceleration measurements, such as 0-60 mph or 0-100 km/h times. It can also function as a trip computer, offering statistics on fuel consumption to help users track their driving efficiency.

Advanced Vehicle Coding

For owners of certain VAG group vehicles (Volkswagen, Audi, Skoda, Seat) built on MQB, PQ26, and MLB-EVO platforms, Car Scanner ELM OBD2 supports coding. This capability allows users to change hidden settings within their car’s systems. Documented exclusive functions include Video in motion (VIM) and Mirrorlink in motion (MIM).

Connectivity and Compatibility

To function, the app requires an external OBD II Wi-Fi or Bluetooth adapter to establish a connection with your car’s ECU. It is designed to work with any vehicle that uses the OBD 2 standard, which includes most vehicles built after 2000, and some models as far back as 1996.
