DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag

[SEALL]

thanks! i will check it out,one more question:the Resistors should be 240 ohms/390 ohms/910 ohms and 1/8W or 1/4W? or whether it should be with limits?

Correct for the values. Either 1/8W or 1/4W is fine.

Thanks for all,i checked the PIN 40 on the ECM yesterday,but it was no volts on it,so i can confirm that the CC pin on the ECM wasn't actually used for Chinese market.
thank you for all the help.

Maybe you should buy a USDM ECM off ebay. Then, you'll have the only Yaris in China with cruise control.

hahahaha~~~good idea！but how much the USDM ECM? and I need to change the ECU or ECM's Program? or install it directly into the in-situ and do not change anything?

I'm not sure about the compatibility, but USDM ECMs can often be purchased for under $100 off ebay. The engine type, transmission type, ABS yes/no, and VSC yes/no are important to match when swapping ECMs. Our USDM ECMs are for 1NZFE and 2NZFE engines. I haven't noticed which engine you get over there.

Dear Scott,

Thanks for the update .. I dont think the Yaris in the UAE is European.. I checked up the VIN and it states my car is made in Japan and is ment for the GCC market. I was really looking forward to install the CC ,, is there any other way to do it or any how can I check if the ECU is having the CC function?

First, make sure that you are really in pin 40 of the ECM.

Second, what is the part number on the label of your ECM?

My yaris's engine is 4ZRFE,1600cc,Super ECT 4-speed AT,ABS yes,VSC no,maybe only have the 1600cc engines of the Chinese market.

I think you are correct. Are you able to see the part number label on your ECM?

I don't know what's the part number,I saw the lable on my ECM,there are some number on it:89661-0DA20 ; TD275100-9872 ; C90.

89661-0DA20 is the part number. It looks like it is a China specific ECM.

Anybody know about relevant wiring in 2010 liftbacks?

I'd like to try this on a 2010 2-door base liftback purchased in the US!

2010 is identical to 2009 for the DIY cruise mod.

It seems useless to put on a USDM ECM.

Agreed. I don't think it would be compatible with your engine.

Although there is no success, but very grateful to you for your help,And your very pleasant exchanges.

I'm going to try the 4 button set up and plan on getting it installed this weekend. I decided to put all the resistors in their own enclosure and attach the buttons with butt connectors. I can tuck the module up under the dash and if a button ever goes bad (read as: When I spill my drink into one), I can simply unplug the switch and replace it without any soldering. I have some buttons but I'm going to see if I can find something better.

I'll take more pics as I progress.
I couldn't find the right resistors so I had to stack them to get the right Ohm requirements.
I've got about $24 dollars into it so far.

Added more pics. I haven't settled on where I want the buttons or what type I want so I installed the cheap ones I had next to the Aux Port for now

I mounted the CC module on the cross bar under the steering wheel. The box has to lay on its bottom, not on its side as shown in the first picture of it. The steering column cover wont fit if it mounted on its side.

It works! CTScott, and everyone else that contributed, thank you for all the great info.
