DIY - 2009 Cruise Control for $10, without pulling the steering wheel and airbag - Page 11 - Toyota Yaris Forums

ditso · 10-16-2009, 06:38 PM

I really enjoyed CTScott's instructions on how to add cruise control. I haven't purchased a Yaris yet but I'm planning to do so this spring. Since CTScott obviously is a very smart individual, I was wondering whether he could provide instructions on how to add a headphone jack in approximately the same location as the two cruise control switches. The jack would not necessarily need to shut off the speakers in the car--just tap into the sound system. Before someone goes ballistic on how "unsafe" this is, I would like to point out that my drive is very early in the morning on an interstate with very little traffic. I would take the headphones off when driving in serious traffic. Thanks.

2010 Yaris 5door Auto, DIY cruisecontrol switch installed. pardon the red sharpie treatment, it needs another coat.

it's teh bomb. the switch action feels like toyota engineered this thing, it really does. easy to hang yer arm off the
armrest and + or - ...and it is precise.

So I think I might have screwed up somewhere, I just notice in the last day or so after I installed this mod (stills not working but I havn't had time to track down the problem). I noticed that the airbag off light on the passenger side will light up only for a bit randomly while driving. The airbag on light works fine when someone is riding with me. Any ideas on what I did wrong?

The two are probably unrelated. The airbag light occasionally flickering may be due to the empty seat weight calibration being off.

For the cruise issue, start with your connection at the ECM. Make sure you are in the correct pin there. If you just want to verify that the cruise and airbag issues are unrelated, disconnect the cruise wire to the ECM.

Posting pictures of your connection to the ECM and you resistor setup/wiring to it will help as well.

Can you track down the electrical wiring diagrams for the Chinese market Yaris? Someone from Europe tried the CC mod and it didn't work. Once I got a copy of the EWD for their market, I found that the CC pin on the ECM wasn't actually used for their market.

OK，thanks for all,and do you know how much volts on pin 40?

Pin 40 measures 12 volts with nothing connected to it.

SEALL · 10-27-2009, 10:53 PM

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.

SEALL · 10-28-2009, 09:31 PM

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.

I installed the CC, when I switch it on the speedometer jumps once , pressing the set buttom dosen't set the speed . While installing , by mistake I connected the 12 V supply instead of the ground which stalled the engine immediately . Can anyone help me if I have screwed up the CC function of my ECU. The car is running fine otherwise.

So far it looks like only US and Canada Yaris have the cruise functionality built into the ECM. In the UAE do you get European Yaris? If so, cruise is definitely not built in.

sabya78 · 11-01-2009, 03:09 AM

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?
