From what I have seen it is supposed to be ISO 9141 compliant.

yeap it is. but it wont link. but now i notice something in this scanner. i found a pending code. p0172. im not sure if it was saved in the scanner. is it possible that the scanner detected something? even if the scanner it does not linked??

That may be possible. The scanner may be trying to also maintain a communication stream that the ECM does not support.

JDM cars don't support OBD protocol from my experience. I bought an ELM327 scanner and it refused to connect to my Vitz. I've ordered a Toyota Techstream scanner and I'll see how that goes.

no luck still now.. still check engine light went off
but i like to know with scanner does communicate with my vehcile
any one?

ELM327 cannot work with JDM Vitz, whatever the advertisements say it wont work. Yes the protocol is supported but the way the ECU talks to the software is the problem.

Toyota techstream scanners work with JDM Vitz, and the more expensive JOBD scanners.

I was really disappointed with ELM327. I really wanted Torque in my car, I already bought the app and almost bought a tablet so I can have it permanently in my car.

If I can get my hands on a Vitz ECM, I am going to build an ELM327 compatible device to work with the MOBD protocol, which the JDM cars support.

I will be your first customer :D

OK. Then, find me a cheap ECM in a junkyard over there. I actually had a JDM one and a while back I harvested parts off of it, as I didn't think I would ever need it for anything.
