Car Diagnostics With Elm3
View on Chrome Web StoreChrome will indicate if you already have this installed.
Overview
This application allows you to connect to the ECU in modern cars with a chromebook (Or computer running chrome) and a ELM327 adapter. For a chromebook the USB version of the ELM327 adapter is recommended (The bluetooth drivers are unavailable on the chromebooks I tested)
The app gives you access to a list of available sensors on your ECU and their values, a realtime view of values chosen by you with a history graph and the list of trouble codes (The check engine light). It also allows you to reset the check-engine light.
