OBD2 Protocol? Options

[GripNSipp]

Does anyone know the protocol 6th Gen Celica's use? I bought a cheap OBD to Bluetooth dongle and it powers on in my '99 liftback but none of the apps I try to use it with will connect to the engine. After some research I've came to the conclusion that the cheap dongle doesn't have the right hardware for my car's protocol. I think I'll try buying a different one I just need to know what protocol I should look for.

This is the dongle I bought and these are the protocols it supports
1.SAE J1850 PWM(41.6Kbaud).
2.SAE J1850 VPW(10.4Kbaud).
3.ISO9141-2(5 baud init,10.4Kbaud).
4.ISO14230-4 KWP(5 baud init,10.4 Kbaud).
5.ISO14230-4 KWP(fast init,10.4 Kbaud).
6.ISO15765-4 CAN(11bit ID,500 Kbaud).
7.ISO15765-4 CAN(29bit ID,500 Kbaud).
8.ISO15765-4 CAN(11bit ID,250 Kbaud).
9.ISO15765-4 CAN(29bit ID,250 Kbaud).
10.SAE J1939 CAN(29bit ID,250*Kbaud).
11.USER1 CAN(11*bit ID,125*Kbaud).
12.USER2 CAN(11*bit ID,50*kbaud).

It connected fine in a Chevy Prism I tried it in but wouldn't work in my friend's Honda Civic either

What app are you using? I used dash commander and it worked fine.

I tried that app and I got this. Do you remember which dongle you used?

Would try cleaning the OBD-II port with contact cleaner and putting the dongle in and out as pins could be corroded. If that doesn't get it would look into Torque or some other free apps. All else fails this one is guaranteed to work on all vehicles: https://www.amazon.com/BAFX-Products-34t5-B...=obd+ii+scanner

Screw it might as well spring for a nice one. Should be easy to return as well. While I was researching all the OBD stuff I came across others talking about Toyota Techstream. Is there anything cool you can do with that?

when you buy a dongle you're supposed to look at the supported apps to run it before buying it. Apps like Torque.

I used this connector:

It will work with the stock 5sfe ECU.

ok I bought the fancier dongle and now it works. According to Torque the Celica's protocol is J1850 VPW(10.4Kbaud).

Glad to hear you got it sorted.
