BUDGET ODB-II CODE READER - Toyota Yaris Forums

Martin Bruce · 12-13-2022, 08:14 AM

Rather than go to the local Garage / Shop again, who charged me £30 to read the fault codes, I decided to buy my own cheapie OBD-II connector and use an app on my Android smartphone. The Garage tried to scare me off getting an adaptor when I mentioned it by saying they knew a customer who had blew his ECU up using his own one.

Still, I got a KONNWEI KW902 OBD2 BLUETOOTH ADAPTOR off eBAY, China for about £15 , it took a few days to arrive.

Some might prefer a more pricey professional OBD2 Adaptor, where the firmware is written/ installed by a well-known maker.

I downloaded the 'Torque' Engine Management App (available on Google Play).
Connecting the app with the Adaptor is a bit hit and miss, somtimes takes 2 or 3 presses of the button on the adaptor, using Bluetooth, but does work.

I was able to read the fault codes and save them to a log file, and even clear them from the ECU. I carry the adaptor in the Yaris now, just in case.
