Code reader app/dongle?
 

Are there any good options of an app that can be connected to truck with a dongle to read codes/diagnostics? Maybe a Bluetooth option and an app that can do multiple vehicles?

Thank you.

You can buy an ELM327 OBD2 reader and download the Forscan Lite or Torque Lite apps if you have an Android. They work via Bluetooth.

Thanks I'll check it out!
