DIY Cruise Control FAQ (2006-2010 Yaris) - Toyota Yaris Forums

Hey CTSCott - if you remember I bought a CC stalk from you along with the wiring kit. It worked fine for a month or two and you may remember me posting that it stopped working occasionally and would also sometimes make the car accelerate on it's own.

It eventually stopped working entirely but just now had time to go out with a multimeter to test it. This was done about a foot of wire away from the computer thingy (on the firewall in the engine bay) at one of those snap-close connectors I used. The ignition was on (I know you told me to do it with the ignition off, but hopefully this works too) but the engine off.

Car on but engine off: 12.3v
With the on/off button held: 0.2v
Held down: 6.1v
Held up: 3.4v
Held toward: 8.6v

Any idea why the CC wouldn't be working AT ALL? I have no idea what these values are supposed to be. I'm concerned that maybe the wire thickness I used may be too much, but I have no idea how these things work. I think it was the same type that you used in the wiring kit (had to buy extra from radio shack).

Thanks a ton for your help!
