Hello everyone,

I would like to get your experiences on the ELM327 OBDII scanners. I just bought a couple (yes the cheap ebay clone ones, but seller assures that they are good quality and work well) . I am having some trouble pairing it up to my Vitz.

I have the Torque pro app and some Scantool app on my computer. Now they both detect the adapter with no problem, but I cannot get any information from the ECU. There's not much information on the web about these adapters so I checked here and some of you have experience with these.

I saw a video on youtube of someone who used this with their Yaris and it was working quite well.

So, my problem is that I cant read anything from the ECU. The app and bluetooth connection seems fine, but I can't get any readings (RPM, speed etc). Any suggestions on what I should try with settings or anything else ? I am really keen to get this to work. Also if the adapters are faulty I want to return them then.

I've got a 2005 Vitz RS 1.5 JDM spec.

Thanks.

here's that link for youtube video:

I heard on here that Japanese market cars use a different OBD standard, not OBDII.

Japanese Toyotas use M-OBD, rather than OBDII.

The off-the-shelf apps won't work, but the ELM should actually work if commanded properly. Do you have a Windows based laptop that you can connect to the ELM, where I can either send you a custom app, or walk you through some special commands via Hyperterminal to do some testing?

I have actually been wanting to get access to an M-OBD car to test some theories for a device that I have developed.

I have an ELM327 and it works great using the Iphone with the application fuzzycar. Sometimes you just have to restart the programs several times to get it to connect.

You have a US car, which is OBDII compliant. The OP does not.

I personally have not seen any bluetooth or wifi OBD devices that are compatible with Japanese market vehicles (M-OBD, rather than OBDII). The second issue with that would be finding software that supports M-OBD for the phone or tablet you want to use it with.

At this point the best option is the Toyota Techstream system, but that is USB and requires a PC to run the software.

I too was disappointed to learn that my Jdm Vitz RS used M-OBD. I also purchased the elm327 on ebay.

CTscott I can be the test person if u want.

I also purchased one, although on amazon. Wish it read more sensors, but it does the trick for me. I use it with torque app.
No issues with connectivity on my '07 Sedan.
Remember to remove the adapter every time you turn your car off though, drained my battery overnight!

Like I said to someone else above the O.P. and others asking have Asian market Yaris which are not OBDII. All US/Canada market cars are OBDII compliant and therefor do not have the issue of the O.P.

Guys, I've discovered an android apps that talks to JDM toyota using ELM327

Its called hobdrive

Its bloody expensive and its very user UNfriendly.
The demo is free and may give you some basic idea of how it is to use.

Is Toyota Techstream system compatible with M-OBD? If I am not wrong, it support OBDII protocol the same as elm327

Techstream supports a few Toyota specific protocols as well as M-OBD and OBDII.

Just an update guys, I may have cracked getting Torque(pro) to work with our JDM Vitz. So far I have managed to get it to successfully connect, but its not getting any real time readings. I will be trying out a few more things. Hang tight

Try this. This code in the vehicle profile allowed torque pro to read data from most of the sensors in the ECU via an ELM327 reader.

Tried it, does not work. What type of adapter are you using ?

I managed to get this other shitty app hOBDrive demo to get some readings, but for some reason I cannot get Torque to get readings.

It's connecting with your code, but no readings. I tried some more codes I got from the net, same result.

Rakin's NZT240 predates CAN bus (depending on the year). If that is the case, then the comm would be completely different from your 05 Vitz.

ELM327 $6 adapter from ebay. It only works on 2002-2006 cars, tried it on a 2008 NZT260, didn't work. :(

The app OBDDash free on my windows 8.1 tablet was able to connect well enough with my 2007 Vitz RS using ELM327 to read DTCs.

Hi KTS,

Did you have to use any custom initiation strings ?

Oh man I don't want to buy a Windows tablet. If these things work on so many other devices/platform I am sure there is a way to get it to work with Torque.

I am not sure what you mean by custom initiation strings.

I just installed the app and clicked on connect and I was able to read the dtc associated with the check engine light but provide no real time data.

I then started unplugging connectors in the engine bay and checking the codes to verify if it was reading the correct codes and it was.

Also the mini vci cable and techstream v10.something works on my windows 8.1 tablet.

Ah I see.

Yea some apps can read the DTC but no real time data.
hOBDrive shows real time data but its $25 and has a shitty ui.

It must be something small. I've managed to get Torque to connect successfully to the ECU just no readings.

I am going to try some more apps I found recently online

I am hoping you will compile a list of apps and their settings that connect and show either dtc and rtd or both

Sorry , don't want to sound like a stalker here. I am the developer of the OBDdash app. I found this post via google.

I found it surprise that the live data does not work for you given that the check error code works fine. Can you please provide a bit more details about this issue?

On the gauge screen, if you tap on any empty gauge, does the app shows a flyout? if so, does the flyout contains any sensors? If there are sensors listed on the flyout, single tap on any of them should assign this sensor to the gauge, and live data should be displayed thereafter.

Hi FredsToolbox,

I do not have the elm327 atm. I lent it to a friend to check his car. As soon as I get it back from him ill try what you suggest and let you know.

Great job on the app!!!

Hey nice to meet you FredsToolbox.

Any chance of an Android version of your app ?

Sorry, wasn't any plan on the Android move :(

On the bright side, when I did a search of OBD on google play store, I think it returns over 100 apps :)

The reason I made this on Windows tablet is just to fill the void as there was Zero OBD app for Windows tablet at the time I started :)

FWIW, I bought a cheapish ODB scanner from Ebay which was meant to be for the Yaris. It ruined the entire car. Nothing worked afterwards. The engine idled at 300 revs, the gearbox didn't work etc etc.
So, I bought another specific to Toyota (can't remember the name but it was a Canadian company). Rubbish. The bluetooth connection never worked and it told you wonderful things like your road speed only when it did work
