## What is Talk2Otto?

Talk2Otto reads your vehicle's own diagnostic computer and hands what it finds to OTTO, your automotive best friend at OttoBotRepair.com.

Plug a Bluetooth OBD-II dongle into the diagnostic port under your dash, tap Connect, and Talk2Otto shows you what your engine computer is reporting right now:

- Trouble codes behind the check engine light
- Engine RPM, speed, coolant temperature and throttle position
- Engine load, fuel trims, intake pressure and air temperature
- Timing advance, mass air flow and oxygen sensor voltages
- Whatever else your vehicle supports - the app asks your car which sensors it has instead of guessing

THEN SEND IT TO OTTO
Ask OTTO for a four-digit code on OttoBotRepair.com, type it into the app, and your codes and readings land in that conversation. OTTO can then work through them with you: what the codes mean on your vehicle, what to check first, and what the repair usually involves.

WHAT YOU NEED
- A Bluetooth Low Energy OBD-II dongle (widely available for around $25)
- A car or light truck sold in the United States from 1996 onwards, or a vehicle sold in Europe from 2001 (petrol) or 2004 (diesel)

WHAT IT READS
Standard OBD-II data as defined by SAE J1979. Manufacturer-specific systems such as ABS, airbags, transmission modules and tyre pressure monitoring need dealer-level tools and are not covered. Electric vehicles expose very little standard data.

PRIVACY
Nothing leaves your phone unless you enter a code and send it. There is no account in the app, no location access, no advertising and no analytics.
