DIY Cruise Control on 07-08 Yaris (step by step)

[CB900F2]

Scott... It appears for my 08 CND Sedan, the wire run from the ECU to AD4 is there, and what is missing is the wire run from AD4 to D3..

Since AD4 is tucked way in the top left side of the inner dash, not sure if you have ever taken apart your Yaris's top dash, and if you have noticed if both ends of AD4 have the light blue wire.. I am really hoping Toyota has the wire run from AD4 to D3, but only decided to tuck away the run from AD4 to D3 some where.

I would find it odd that all of the other wiring is there as even the clutch switch is there, but they manufactured the wire harness with only missing the run from AD4 to D3

What do you think?

Negative or positive ? also the pin 40 on the ECM doesnt contain any sort of power when i check it with a power meter. Is it supposed to have any pulse or something? i am just a little worried to not damage the ECM by doing this sort of a setup. Is it safe ?? 100% ?? :p

I don't believe that Yaris for your area have the cruise functionality. Besides that, the black wire is the horn. There are two additional wires that get added to D3 for cruise control.

Getting to AD4 requires removing the top of the dash. The wire from AD4 to D3 is definitely not tucked, as it would be part of the harness that also contains the horn wire.

In my area YARIS is not available, so i had to buy it from JAPAN. Does it work with JAPANESE models ??

[sheraz2000]

If the Belta has blue and brown as the other two wires in D3, then it should work. If it has the cruise control indicator in the cluster, then to test it just jump the blue to the brown with the ignition on and the CC indicator should light.


For the other, which just has the black wire, the best quick test is to measure the voltage on the ECM pin (A21-Pin 40) with the ignition on. If CC is active on the ECM, then that pin will have 12V on it.

Hello!
I have a question, I hope you all don't mind....
I have an 08 liftback, MT, without wiring. I've installed the buttons and the wiring to ground and ECM. I don't have a harness for the clutch switch, so I need to rig the switch to go into the fuse box in the engine bay. (If this is wrong please correct me)

The clutch switch has two contacts, so I assume I run two wires off of those contacts into the fuse box. My question is which wire goes where? Looking at the picture on the top of the 4th page of the pdf, I'm not entirely sure.

Would this work on a 2009 Sedan?

Got my cruise stuff, now I'm just waiting for a day off to go get it installed.

Correct on the clutch switch wiring. The clutch switch goes to the blue wire indicated below and the white wire, to pins to the right of the blue.

Thanks for the response! Checking to make sure I understand:
So both wires from the clutch switch splice into the blue wire and the white wire is moved to the right of the blue?

No, one wire from the clutch switch connects to the blue and the other connects to the white.

Thank you so much.

Cruise control works great! A big thanks to everyone who contributed!

thanks for reply.

For the European Yaris, you need to use an aftermarket cruise control, since the European ECM doesn't seem to have the function built in.

Check out the link below. This Belgium based company makes an aftermarket CC for European Toyotas:

This thing means that toyota don't make too many productive lines for different cables, why they should do this for ECM?

I don't know why they have different programs for the ECMs for the different markets. I would think that people all over the world would appreciate cruise control.

well, when i opened up the D3 connector on my belta, i got these wires. Tell me what to do from here forward. SORRY about the blurry pic, was taken from my mobile cam. But the wire colors r pink, orange, grey and black. there is no blue and brown cable. How to check if my car has CC in ECM.
