Steering Wheel Controls - Page 5

Make sure it's set to ohms, and try between TX+ and TX-. When you hold a button down you should see the meter change. If not, try between ACC and TX+ or ACC and TX-.

Still nothing!!

But when I try to measure voltage through GROUND and TX- I have 2,5V on idle and 2,4 when pressing one button...
But with TX+ I get 0,6V without a change!!!

I don't want to pay $120 to get new steering wheel controls IN CASE mine don't work anymore!!!
I suppose the only solution is to try from a friend's controls!!!!

THANK YOU for ALL the help!!!!

Maybe it really is digital? I don't think you broke it, it's just different.

One more possible thought: Does the SWI-X say it works with your exact make and model car? I think they assume it works with some year range.

No, it doesn't have corolla (although it has some other toyota models)...
If it is digital isn't there a way to interface it??

I never got your email. I started changing the source code to make it into a girder plugin, but I never finished and I never backed up my original. The codes currently broken and I'm in the middle of about 5 other projects, but I will either try to put the code back and get it compiling again, or just post it as it is now so you can get an idea of how it works this weekend.

I will also eventually finish making it into a girder plugin, but probably won't have time till at least january.

Do you have the service manual for your car? This is how I figured mine out. It actually had the exact resitances to test for and even how to test them.

If it is digital it might say which bus or something it uses, but probably not how to test it.

I've searched for the service manual on the net but cannot find it!!!
do you know a possible link? It is the european version!!!

Do it on eBay. Just do a search for toyota corolla service manual.

been searching for the past couple hours and havnt really found anything solid yet, keep getting thrown off by special cases, such as using existing car switches and such, but if anyone could help me i would be grateful

, i dont have any steering wheel controls however i have been wanting to put a few buttons on the dash somewhere to control volume, tracks and such. i was just wondering what i would need to build this, i would want a minimum of 3 up to 7 momentary switches that this program (or any other if anyone knows of anything that would work) could read. im decent with soldering and pretty good with fabrication w/ plastics/bondo/fiberglass so im not really limited there. just need to know how to hook up the buttons to the joystick port (i have a old joystick that i can rip apart).

You can use phidgets kits...
But you have to make the program

Nic · 09-13-2004, 06:37 AM

easiest way is to use the serial port and girder, try google for girder or something

Curiosity · 09-13-2004, 10:58 AM

You could also use the joystick buttons connected directly to the momentary buttons you want to use and the standard girder joystick plugin will do what you need. If it's USB you'll get more buttons out of it. If it's the joystick port, I think it's limited to 4 unless you use a combination of inputs and diodes.

OK, jumping in here at the end (and at the deep end), I would certainly like to preserve my steering wheel controls when I build the in car computer, however I haven't done circuits and just can't get my head around the diagram god of cpu has done.

If 5v is supplied by the gameport, what is the power node doing and where is it coming from? Where the nodes (the red dots) join, how is this done physically? Would you do so by soldering onto a PCB or by simple joining and soldering of wires?

See, I'm a noob extraordinaire!
