Toyota Avensis

Hi,
eigentlich wollte ich bei meinem Avensis T22 facelift 'nur' den AUX-Eingang freischalten und die Lenkradfernbedienung bzw. die Knöpfe am Radio dazu benutzen, irgendwelche Programme auf meinem PC zu starten. Nachdem ich die Software von dem CAR2PC-Adapter heruntergeladen und festgestellt hatte, das diese ja wohl der allerletzte Rotz ist, habe ich mich entschlossen selber sowas zu basteln. Also habe ich angefangen Datenblätter und Pinouts zu wälten um dann mit einem Scope herauszufinden, daß auf den Beiden TX-Leitungen (TX+ und TX-) ca. 2,5V anliegen (+/- ca. 0,3V - halt das, was da an undefinierbaren Signalen herumwuselt). Relativ enttäuscht (da ich damit grade mal garnix anfangen kann), bin ich dann auf dieses Forum gestoßen. IrDo you have any idea if that's a...or rather, WHICH CAN bus am I 'finding' there?
If so, HOW CAN I GET SUCH A DEVICE AS QUICKLY AS POSSIBLE?! - (Yes, yes, PM to admin...)

Here's a scope excerpt that I took from TX- (top) and TX+ (bottom). Resolution: 2053x594, size: 43.716 bytes (I like gif ) http://www.rienesl.de/images/ich_mach_lauter.gif
Unfortunately, I don't have a two-channel oscilloscope, so I had to capture the signal twice and put the results together.

Damn, it looks like I caught an IEBus. At least that's what the datasheet of a chip from my steering control told me. I am now trying to proceed under http://www.softservice.com.pl/corolla/avc/index.php or http://www.softservice.com.pl/corolla/avc/bboard/. Thanks and keep up the good work!

Hi Martin,

Just check Google under 'Prius hack,' and you'll find things like...

http://www.hybridinterfaces.ca/install.html

und auch andere Umbauanleitungen für den Prius. Vielleicht findest du da ja auch Hinweise in welchen Farben Toyota seine CAN-Bus-Leitungen so zu bemalen pflegt ...

Hi,
Unfortunately, the information there only refers to the CAN bus. I already found that page - still, thank you!
Best regards,

Hey everyone,

I've also recently acquired an Avensis with the facelift, and I'm also looking for a way to control the steering wheel controls. However, I had some other ideas that would be very useful for this car.
For example, the development of an embedded control unit that automatically closes all windows and folds in the mirrors when locking the car, and which, upon repeated pressing of the unlock button, opens the windows again (e.g., by pressing three times) and unfolds the mirrors (e.g., by pressing twice). A convenient turn signal function can also be easily implemented (a single tap causes it to blink three times).
For this purpose, I am looking for tax codes within the CAN bus, as well as information about affordable chips that can be used for this.
We could turn this into a great open-source project, as there are likely many more people who could benefit from these solutions.
Perhaps someone has some information or ideas on that topic.
Best regards.
Alex.

Hi,
Sure, here's the translation of the text from German to English:

'A few notes:'
'I've also recently acquired an updated version of the Avensis and I'm equally...'

'However, I had a few other ideas that didn't quite fit in with...'

Um, the Avensis doesn't have foldable mirrors...

> when the unlock button is pressed repeatedly, ...
> Tap the window button again (e.g., three times) and the mirrors will return to their previous state.
> opens (press twice).

It's going to be difficult; the window control unit is not connected to the turn signal relay in any way.

A comfort blinker is simply that as well.
> to implement. (Tap and make it flash three times).

I've already created it. If you're interested in the schematic diagram, just let me know. Otherwise, you can simply buy it from Conrad for 40 euros.

'For this purpose, I am searching for tax codes within the CAN bus and information about...'
Chips that you can use for this and that don't cost a fortune.

Unfortunately, the Avensis uses the IE-Bus (AVC-LAN) for the remote control and the onboard computer, which means it is not compatible with CAN solutions. I am currently trying to recreate the circuit of <!-- m --><a class='postlink' href='http://www.softservice.com.pl/corolla/avc/'>http://www.softservice.com.pl/corolla/avc/</a><!-- m -->, but it's not working very well, as the whole thing is still in a prototype status, and I don't understand much about microcontrollers...

Morning, Martin.
der neue Facelift Avensis hat elektronisch einklapbare Spiegel. Ich hab dafür einen Knopf links neben dem Lenkrad. Das einzig Dumm ist nur, dass man drauf sehr leicht vergisst. Deswegen dachte ich mir, da hängt eh alles am CAN Bus und man macht einen Monitor Steuer Kastl, dass am Bus lauscht, wann die FB Betätigt wird und dann klappt er die Spiegel über ein Signal am Bus ein und macht die Fenster zu. FüI've seen something like that before, for example on a BMW 5-series, but not for the Avensis.
I assume you have the Avensis model up to 2006, right?
'If you manage to figure anything out about the steering wheel control module, I'd appreciate any information you can share. I'm planning to install an Alpine radio and would like to get that function working.'
Best regards.
Alex.

I just found this part on the Conrad website.
<!-- m --><a class='postlink' href='http://www.conrad.de/goto.php?artikel=852637'>http://www.conrad.de/goto.php?artikel=852637</a><!-- m -->

Regarding the open-source aspect, I was more thinking of a module that handles these tasks. There's also software involved in that, so it knows which signals are currently coming through the bus and what actions to take based on those signals.

I don't want to install a car PC in my car; I prefer a 2DIN navigation system instead. A PC consumes too much power and crashes too often.

Best regards.

Alex.

Hi Alex,
The problem is that you are completely wrong here in this thread. I actually have an Avensis facelift, and it definitely does NOT come with folding mirrors, but that's simply because I have a T22 (as stated in the first line of my first post). You have a T25, and there have been quite a few changes since then. Since I don't have any wiring diagrams or maintenance manuals for this model, I unfortunately can't help you with that at all...
Best regards,
Martin.

Oops - oh, I see - thank you - I'm not yet very familiar with Toyota's internal part designations - I used to have a 626 and now I'm just getting acquainted with the subject matter .
But maybe someone who also has a T25 and some experience with it, or enjoys tinkering, will stop by .

Thanks for the tip about Conrad.

Best regards.

Alex.
