DIY Cruise Control FAQ (2006-2010 Yaris)

[johnliu38]

I wodner if I can do the same trick on my Taiwanese version of 2010 Yaris Hatch Back because I heard its ECM has built-in cruise control function, but got locked. Some people charge US$250 for hacking the ECM and enable the CC function... Not sure if it's really locked or not... Is there anyway I can do to identify the CC function of my Yaris?

Check to see if you have the two wires on the steering column for cruise (and the two cruise control icons on the cluster). If they are there, then you can do a real quick test by grounding the blue wire (with the ignition on) and the cruise control on icon should light up. If the wires aren't there, then you can check the voltage on the ECM pin 40. If there's 12V on that pin with the ignition on, then cruise is enabled, but just the wiring needs to be run.
