A diagnostics app that works through an OBD2 adapter

Car Scanner ELM OBD2 is a diagnostics and trip tool that reads data from the car's engine management system, also called the ECU. It needs a Wi-Fi or Bluetooth OBD2 adapter based on the ELM327 chip, which plugs into the car's diagnostics socket and passes data to the phone.

The listing says the app works with any car that uses the OBD 2 standard. That covers most vehicles built after 2000, and some back to 1996.

Reading and clearing fault codes

The app reads diagnostic trouble codes and can clear them, in the way a standard scan tool does. Each code comes with a description from a built-in database of DTC codes. It can also read freeze-frame data, which is the sensor state saved when a fault was stored.

Mode 06 shows results from the ECU's self-monitoring tests. An emissions readiness check reports whether the car is ready for an emissions test.

Live data on custom dashboards

You build your own dashboard from gauges and charts and choose which readings each one shows. The listing also describes custom extended PIDs, which request values the manufacturer does not show by default. A separate screen displays every sensor at once.

A HUD mode projects the dashboard onto the windshield. An acceleration tool times runs such as 0-60 and 0-100. A trip computer mode tracks fuel consumption statistics.

Coding hidden settings on supported cars

Coding changes settings that are normally hidden in the car's modules. The listing covers VAG cars (Volkswagen, Audi, Skoda and Seat) on the MQB, PQ26 and MLB-EVO platforms. Named functions include video in motion, MirrorLink in motion, traffic jam assist activation, drive mode profile editing and ambient light configuration.

The listing also includes Toyota and Lexus cars with CAN bus, some Renault and Dacia models, and several service functions for other makes. It notes that compatibility for some of these depends on the car's modules and firmware versions.

Connection profiles and choosing an adapter

Connection profiles add extra features for specific makes, including Toyota, Mitsubishi, GM, Opel, Vauxhall, Chevrolet, Nissan, Infiniti, Renault, Hyundai, Kia, Mazda, Ford, Subaru, Dacia, Volkswagen, Skoda, Seat and Audi.

The listing recommends OBDLink, Kiwi 3, V-Gate, Carista, LELink and Veepeak adapters. It warns against cheap clone adapters marked v.2.1, saying they can drop connections and slow data reads. It also notes that the app can only show readings the car provides.
