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

[09sedan]

have 2 questions for CtScott the almighty yaris guru:

i have a november 2008 built 2009 yaris sedan (Canadian market)

1. if i use the 2 switch setup, and i turn it on and have to brake will the CC automatically deactivate?

2. how do you tap into the cables on the connector from the on/off switch?

3. is the D3 connector the white connector on the LEFT side of the yellow connector?

Yes the brake overrides CC.

If yours has the wiring from the ECM to the steering column, then you can use splice tap connectors (available from most auto parts stores) to connect to the existing wires. Your Canadian sedan may not have the wiring from the ECM to the steering column, and if that is the case you would need to add the ECM pin.

ok cool thanks for the info!, so D3 connector is left side of the yellow connector ? and if there is a blue wire there, then i can just tap into it, if not i have to run a wire through the firewall to the ecm?

Correct on both.

great news, i just checked and i have all 3 wires, and my dash cluster has the set and CC indicators.

do i have to use the switches you mentioned, or can i use a plain SPST Normally open pushbutton that i can buy from my local electronics store?

Hi Scott,

If I don't have cruise control in Yaris 2008 EECU ( In NZ ) can I change US market ECU and will it start as normal ? Then can I do my DIY CC ?
Cheers.

Possibly, if you have the 1NZ-FE engine. I believe that your cars follow the JDM Vitz wiring. I have not done a pin for pin comparison of the US versus JDM ECMs to see if any pins need to be moved around.

Thanks Scott, If its hard I'll go for this option.

You do realize that that device is not cruise control, but rather a device that makes the throttle seem more responsive?

Ive had my Yaris World cc for maybe two years now. I drove a friends car with stalk cc and HATED it. My four button cc is SO much easier to use!

Question: one button is on/off, another button is set/decel, and button is resume/accel.

What is the fourth button?

Cancel.

Yes I noticed that now. I'm still looking for a CC that I can fit externally.
Cheers SCott...

I have the 2009 automatic with OEM cruise control and the stalk annoys me and frustrates my wife even more. We loved the OEM flick stalk on the old Camry!

Could I tap into the wiring and add this even though I have the OEM stalk? Essentially I'd have two sets of cruise control controls... control controls lols I can't see why I can't do it this way, but I don't want to poke it and end up with no cruise control.

I'd like to add a set of buttons or a joystick somewhere, but leave the OEM stalk in place so when it comes time to sell the car on I can take the secondary buttons out so as to not confuse anyone.

Can you post a picture of your OEM stalk? I am wondering if your Australian CC is different (and perhaps actually an aftermarket system).

If it is actually the OEM type used on the US Yaris, then you can indeed add the extra set of controls by tapping the two wires.

I've had the steering wheel cover off to do the headlight relay mod, and from memory there's just one thick black cable going to this stalk. Presumably that goes back to the same wires you've described though.



Oh yes, this was done by the Toyota dealer before we got the car, so it's as factory as they do it here. I remember asking about the Camry style flick switch and they said something about not being able to do that as factory and they'd have to "put the cruise control in afterwards" so it could be an aftermarket one that Toyota uses.

OK - That is definitely an aftermarket system, so there is a module somewhere under the dash or under the hood that controls it.

Hello,

I just bought a 2011 Yaris, and was wondering if this mod is easily possible on that model as well, i.e., is the wiring present from the ECM to under the steering wheel ?

Thanks!

It is for sure for 2011 liftbacks, but Sedans are not as cut and dry. At least up to 2009, if the Sedan did not have the power package, then the wiring was installed from the ECM to a junction connector under the top of the dash, but not from there to the steering column.

The easiest thing to do is to pop the steering column cover and check for the blue and brown wires on connector D3.
