Steering Wheel Thumb Controls?

Mon Oct 12, 2015 9:20 am

i have a 2012 SE Premium with radio station and volume control buttons on the left thumb, along with bluetooth phone buttons a little lower on the left side also.

Now my right thumb panel is blank, except that i pulled that little cover off (#1 philips from the back side) and found a 4 pin connector wired up to the back side of the cover--all dressed up with no where to go, 4 extra wires to nothing?

Does anyone have right thumb buttons on their steering wheel--what do they control?

Maybe cruise control--wouldn't that be nice.

Interesting. In other Mitsubishi cars with the same steering wheel (Lancer for instance), the cruise control buttons are on the right side.

Do the wires go down through the column somewhere?

Everything electrical on a steering wheel (horn, airbag and any other controls) go through what's called a clock-spring assembly on the steering column. If there is an unused connector on the steering wheel, there *should be* a matching unused connector (for whatever the wheel connector was used for) down on the steering column somewhere. However, it's also very likely that they used a steering wheel from another car which had cruise, put it in the iMiEV and *did not* include any further wiring or connectors for it in the car harness, since they knew it wasn't needed

*If* the wiring is there, boy it would be oh so easy to work up a steering wheel paddle to control regen! :mrgreen:

When you take apart the clock-spring from a steering column, you'll quickly see how it got it's name ;-)

Not as easy as it first looks. There is, of course, the clockspring assembly but it has very few wires. If you look at the wiring diagrams you can see how they do it. In the case of the radio controls, when you push a button on the steering wheel (for example volume +) a specific resistance is sent down the wire that the radio recognizes as the volume + command. By doing this, all radio commands can be sent down one wire pair in the clockspring. I don't know if the cruise control uses the same wire pair or not but the horn and airbag inflator are on their own wire circuits. If you could build a circuit that uses resistances not used by other devices on the steering wheel, then you could control other things (like regen) but the other end of the circuit is another matter. If you are really lucky, the cruise control uses a similar design and it's own wire pair.

A little research reveals that the steering wheel is the same as the 2008+ Mitsubishi Lancer, mirage, etc... hard part, is whether the circuitry is available in the i-miev to handle the buttons :(
GetUsedParts has a 2014 for $75 at http://mandmautosalvage.hollanderapps.c ... 5698171239
Would recommend getting from a salvage yard (vs ebay) since you can get matching steering column, electrical harnesses or other modules... if you later find that you need more parts.

I'm guessing the same thing for RHD, so they can use the same wheel for all global markets?

Perhaps it is where cruise is on other cars that share the wheel.

The same wheel is used in the Lancer, which has cruise control buttons on that side.

One of my local dealers told me the controller/buttons utilizes canbus to run multiple commands over a single clockspring. So even if I bought the butthurtingly :o expensive steering wheel (which btw is an "empty shell" without airbag, buttons++) I would probably still struggle with getting the electronicabamob to work properly.

At the same visit I asked for side mirrors with the integrated side indicators. But even there they believed I would enter a conflict with the canbus etc. Not surprised over the prices here either. Just the empty housing costs a big fraction of a traction battery ... :?

I hope someone will undertake further investigations in these two "coming up" subprojects. Perhaps someone which have access to the very parts needed. :idea:

Mmm... butthurt :shock:

Now that's an enticing i-MiEV steering wheel! Good luck on the programming. These canbus/firmware issues are why I've not gotten into anything more than superficial performance modding of modern vehicle systems, sticking to electrical and mechanical mods on my antiques.
One would expect that by now, hackers would have enabled a crazy new world of customized vehicle software that would enable drivers to monkey with factory settings (with liability waivers). Beyond the 'performance chip' market, I'm not seeing hardly any of this. To you programmers out there- is it just too hard?
