Hi Capp777,

I am still around and trying, but getting no where.

I did try that header but got a “No Data” response.

I was thinking maybe a virtual PID might work so I tried [1a05] and [1a0105] in the equation but got 0 both times.

I have since focused on reading up on the AT commands just to educate myself before I get deeper into this thing.

Thanks

There got to be a way to address only
that module. Sorry I’ve not found a
solution yet. :-(

Capp777,

I really am thankful for your help regardless of whether or not we succeeded. You have gone out of your way and I really appreciate that.

On a different note, the Linear Logic people obviously figured it out since the Scangauge II does have an X gauge which gave the right result.

I don’t know if it really means anything, but here are the inputs for the X gauge (I inserted the spaces to make it more readable):

TXD: 68 6A F1 01 05
RXF: 03 1A 04 41 05 05
RXD: 28 08
MTH: 00 09 00 05 FF D8

It appears the crucial one is the RX filter RXF but I have no idea what is Torque’s equivalent.

Thanks again for your help.

I think its just an oversight with Torque Pro
not parsing the second message. Most people
have extended pids that return TFT. Your
VW is unique in using 0105 which is ECT by
the standards I believe.

The Info you provided looks like it is specifically
looking for the 1A message and using it thus
getting correct results.

Not sure why Ian chose to only parse the first
message as it is not uncommon for function
requests to be answered by more than one
module (but OBD would have expected 0105
to be ECT).

One last thing to try Nx addressing. N0, N1,…
which is equivalent to the A, B,… addressing.
While I don’t expect different results than we
have seen so far… I don’t believe in leaving
any stones unturned.

Hi Capp777,

I don’t have the car with me since my son borrowed it.

I will try the N addressing when I get it back. Meanwhile, does this thread have any bearing on our problem?

I’m not sure any of those commands are
for ISO (They were using CAN).

Your response messages weren’t multiframed.
Just single messages from different modules.

As of 1.8.128 Torque is supposedly able to handle
messages from multiple modules. Torquescan
should show these messages as [fcxxxx] which can
be referenced in the equation. Read changelog for
1.8.128.

Edited.

Hi Capp777,

I tried the headers you listed and there was no luck.

I also tried the N0 and N1. It turns out they are the same as variables A and B, but nothing beyond N1 returns anything.

Thanks

I would be tempted to make a custom pid
with 0100 pid to test which modules respond
and see what header bytes are returned.

And add in settings external PID

Diagnostic start command: ATH1
Diagnostic stop command: ATH0

Just adding to the desire to see trans temp available for the Eurovan.

I have a little newer engine (2003 with the 24valve VR6), but I have not found confirmation that the Torque app is already set up to read trans temp from my vehicle either.

Anyone made a breakthrough for the OP’s 2000 EV?
Anyone know if the trans temp can be read from an ’03 EV?

Thanks in advance!

I gave up. If you find out, please let me know.

Ian is aware of your issue. Hopefully a fix
will be coming in the future.

Capp777,

Thank you and I appreciate it. With that said, I do recognize that VW vans are rather rare, so if Ian cannot get to it right away, I will be fine with it.

Thanks again for all your help. I am just glad that we gave it our best shot. If it didn’t work, so be it.

Best

go to the settings section for “developers”, enable logging traffic bluetooth exchange
Link to the log put here

How do I enable the Android Developer mode for android 7?
We go in the “Settings” and select the section “About the phone (About the tablet).”
Then we’ll scroll down and see “Assembly number”, tap it seven times.
After the seventh tap, the system will inform the user that he has become a developer. So we enable (or open) the mode for developers on the Android-device.

Cintakc,

My God! You are spot on. I am a “developer” now, except I have no idea what I am “developing” :-)

Thank you. I will put up a log as soon as I got one, but I can’t get to it right now. I am camping.

Best

Copper,

Can you retest the Rx addressing using the
latest version of Torque Pro (1.8.158)?

Wishful thinking on my part since Ian has
not updated changelog description and I
can’t test.

Has there been any progress with Rx
addressing for multiple functional
address responses?
