DIY Cruise Control for 2012 Yaris - Good News!

[motoman740]

Sounds pretty straight forward:

-Disconnect the battery for 30 min before touching anything
-Remove the steering wheel side cover
-Pop off the 3 air-bag clips(if you disconnect the airbag I think the ABS light will turn on)
-Connect and install the cruise control stalk to the 4 pin connector
--If you have steering wheel controls for the radio then transfer the 2 wires from the cruise stalk to the 10 pin connector
-Put everything together and cross your fingers

Indeed. the tricky thing is just figuring out the airbag removal, as it is different from the 2nd gen Yaris, with the clips instead of screws.

With the light piece that you mentioned above, I think you meant SRS, not ABS light. But, if you disconnect and reconnect the airbag connectors with the battery disconnected the SRS will not log a DTC and turn the light on. If you were to do it with power, or connect the battery to test the cruise before reconnecting the airbag, then you would get the SRS light.

Good to know.
Also, I was looking at the steering wheel yesterday and I think the clips just hold it in place, and all you need to do is pull the thing straight out.

I think that the clips are holding against a groove in a plastic rod. This is the only other image from the service manual, and it looks like those three plastic rods are positioned where the other image shows to press the clips:

Its just that the base airbag is a little different than the one in your diagrams

I see that now. This is a picture that I snapped when I test drove a 2012 base. Unfortunately with the sales guy breathing down my neck, I wasn't able to poke around as much as I would have liked to. The 2012 base airbag cover looks a whole lot like the 06-11.

Look on the sides of of the lower steering wheel cover for the two holes, where the Torx screws would be on a 06-11.

I shot a few photos showing the pins and how to access them to remove the air bag/horn button. Just a note - I turned the steering wheel for easier access to the pins (thus photos show upside down). I never diconnected the airbag as it will rest on the steering wheel and allow easy access to install the stalk and connections.
