Has anyone installed or had installed a cruise control into a Yaris Hatchback.

It appears to only be a factory option in the sedan and not the hatchback. The dealer says it is not available through him as an accessory for dealer installs.

It seems simple as the cars computers know vehicle speed, have calculation capacity, and have some form of electronic throttle control. Seems like a simple task to add the switches and buttons for human control (???????). But what do I know.

I have found one through Brandon Distributing in MN. I asked for the installation instruction to see how invasive the install was but they only responded that it was easy, made specifically for the Yaris A/T, that there was no vacuum motor, and all was done electrically. I need to know what the unit does to my car before I commit to hacking it up for a cruise control! Anyone installed this unit?

Hi, I had the after market cruise control installed in my 2 door 2007 yaris. My car is 2 months old. The dealer installed the cruise as I bought it from them when I bought my car. My car has been back into the shop 4 times already because it still doesn't work. They have replaced things, even the car's computer and still can't get it to work. That's my experience with the cruise.

Can you tell me the brand name?

The one I found was Rostra Precision Cruise Controls as distributed by Brandon Distributing. This is "suppose to be" the same one Toyota installs at the Port of Entry on the Yaris sedans (supposedly not available on the Hatchback ????). I wonder if the Hatchback does not have the computer software for the speed control function (????).

I have not been able to get enough info to determine how this after market one does it. The one Toyota installs and documents in their shop manual uses the cars ECM computer (embeded cruise control software) to control the speed. Does the Brandon Distributing one do the same? I don't know and Brandon or Rostra refuse to send the installation info that would tell me.

I find it disturbing that yours doesn't work! Please help me by determining what brand yours is. There may be something to the Hatchback not being offered with speed control (???) especially if the sofware for the functionality is not in the Hatchback computer.

Also how does yours not work? All the time, drop out, not Set, not Resume, or ?????

Thanks for any help.

More Info on the Brandon Distributing (BD) cruise control, for anyone who cares.

The BD unit uses the software in the Engine Control Module computer through the electrically actuated throttle (Yaris has no direct mechanical tie between the foot throttle control and the actual throttle...its all electrical). But the BD control head (not the same as Toyota's) is required to be spliced into existing harnesses. Dealer are installing it around the USA. It was developed for a large Toyota dealer and is for sale to the general public as well.

I don't like splicing into the car's harness because if somethng fails in the car the Toyota dealer has very right to blame the BD unit (like the ECM computer blows up to the tune of thousands of dollars).

In looking at the shop manual, it appears all the parts that make up the cruise control are already there (embedded software, stop light switch,etc.) except the control head. It appears that all that is required is to install the Toyota stalk behind the steering wheel and perhaps adding two wires into the ECM if they are not already there (I think they migh be!). I wonder why Toyota dealers are not doing that rather than installing a unit like the BD one that may impact warrantee work??????

Anyone got some insight?

I have written Toyota to see what their comments might be. If all it takes is to install the stalk then that has to be better than the BD unit!

Toyota's official position is the car was offered as an entry level car with minimal options (Hatchback) and was not tested with cruise control. As such, adding cruise control in any way is consider a modification which may impact warrantee (decided on individual case by case, if trouble occurs). They have no plans to offer a dealer installed Toyota factory cruise control. Add the factory parts or the aftermarket cruise control at your own risk. They would not verify that the ECM contained the programming for cruise control or that it was a minimum modification to install the cruise control stalk. Basically you got what you got....no cruise control!

All that is left would be for some brave soul to take the risk and install the crusie control stalk, connect it and find out if it all worked properly. We already know the aftermarket unit works as dealers all over the US are apparently installing the unit and it is working just fine (for everyone but a few....see above post).

I find it interesting that a seperate after market cruise control was designed to use the ECM resident programming (according to BD) but cut into the harness none the less. Maybe getting the signals from the stalk out to the ECM is not as easy as it appears (may need a cable from the stalk through the steering column??). Perhaps more dialog is necessary with BD, if I decide to risk loosing the warrantee.

Still up in the air. The cruise control is really necessary for my leg problem for longer trips that I take about once a month! Darn!

OK...I got all the Yaris cruise control information for those of you that care.

1). Toyota for the California area has no option for cruise control for the Yaris Hatchback, either originally or dealer installed.

2). Toyota for the California area threatened possible revocation of a warrantee repair if sedan parts or after market parts where installed to obtain cruise control, if either caused damage to the car's systems requiring repair. This was to be judged on a case by case basis (its the law, I believe, that they have to prove your modification created the warrantee problem before they can refuse to pay).

3). All the parts and the programming are already in the car for cruise control except the control head (Set, On/Off, Resume switches mounted on a stalk under the steering column in the sedan). What may also be missing is the cable that weaves through the steering column for the stalk (??).

4). Brandon Distributing (BD) makes an after market crusie control for either the Manual or A/T model Yaris. It is a control head (same functionality as the sedan cruise control stalk). The A/T model requires splicing into one wire that goes into the ECM computer at the point where the cruise control signal from the control head normally would enter the ECM. The control head would also be required to be grounded. The unit uses the Toyota embedded programming for the cruise control function. So you get install instructions, and the control head with attendant wiring with the BD kit. There is no vacuum motor for throttle control since the throttle of a Yaris is controlled via an electric motor run by the ECM computer.

5). The BD unit is the dealer installed option developed for the Gulf States Toyota distributor, or so BD claims, but is available to the general public via the internet at their site. Some dealers in the USA may be installing it too (???).

6). I was not able to accurately define what Toyota of Canada is installing but they list a dealer installed optional cruise control, as they would not comment on their units maker.

I have decided that the risk is minimal in installing the BD unit as it is a passive device and cannot hurt the ECM computer even if continuously grounded which would only occur with a wiring error on my part. I might add BD was very helpful in my pursuit of information on which to make this decision. The huge Yaris Shop Manual I found on the internet also helped immensely.

BAD NEWS!!!!!
My Toyota mechanic friend says the California Yaris Hatchback's have a different computer than cars from different parts of the USA and Canada. They tried to add the cruise control to four different Hatchbacks and none had the progaramming in the ECM computer for that feature and would not work. They even tried the sedan ECM computer in the Hatchback with no luck.
Before doing anything for a crusie control I think it very wise to find a dealer who has successfully installed one! Californians are screwed, again!

I feel like a Yo-YO!

Rostra responded that they DO NOT use the ECM programming and it is inconsequential that the ECM programming is there or not. The Toyota mechanic friend was using just the Toyota factory cruise control stalk and relying on the ECM cruise control programming to be there and that apparently is why his approach didn't work.

The Rostra unit, according to their latest direct communication (not through BD), taps into the electric foot throttle wiring and has its own computer. The car's ECM does not even know the cruise control is controling the throttle electrically and not the driver's foot. This iscompletely different than what BD told me!

I think it is time to commit! I'll buy the Rostra unit (not through BD if I can help it). At least I got the name and email address of the Rostra Engineering Manager. If I have any problems I'll contact him directly.

The Rostra 2006/7 Toyota Yaris Cruise Control arrived today and I reviewed the instructions. I did not buy it from Brandon Distributing (BD) as he led me completely astray when I asked technical information on the unit and its installation. Instead I used M&R Electronics who had pictures on their web site, unlike BD, and understand the unit so well that they want to be the technical support for it rather than Rostra, even though Rostra has technical support for the unit. It appears Rostra uses M&R as consultants on occasion for some of their designs, according to a sales rep for Rostra.

Anyway, you are required to tap into about four wires under the dash: two for brakes, one for the Vehicle Speed Sensor, and one for power. In addition you must route a wire through the firewall to the transmission connector to tap into the Neutral Safety Switch wire. The harness supplied also has a ground lug that has to be run to the body. The power lead includes a fuse for the Cruise Control Unit.

There are two modules, the Cruise Control Module and the Interface Module, with all the required harnessing. The Accelerator Pedal Assembly normally tells the ECM electrically what speed you want. For this system you disconnect the exiting connectors to the pedal assembly and insert the cabling provided. It interrupts the normal pedal signals and inserts the Cruise Control signals when the Cruise Control is on and reverts back to your input when the Cruise Control is off. There is a stalk with the control switches (on/off, set, etc.) that you must mount near the steering wheel (??).

The kit seems very complete and the instructions adequate but the quality of the picture figures leaves a little to be desired. I suppose once you get into it the lost picture detail will be deemed unnecessary (??). My son, a former mechanic, will install it with my help when he gets time. I could do it myself but under the dash work is tough on me at my arthritic age.

I m so sorry about all the confusion. The kit is much as I initially expected (I installed a digital Cruise Control more than 20 years ago on a Nissan) until BD lead me totally astray creating all the confusing about whether the Rostra used the Yaris's ECM Cruise Control programming (which it most definitely does not). I also learned, in a phone conversation with a Rostra sales rep that they have sold about 3500 units for Yaris's with only one known failure (bad switch in stalk). I'll let everyone know when I get it in and working.

THE ROSTRA CRUISE CONTROL WORKS EXCELLENT!!

My former mechanic son installed the Rostra Cruise Control per the excellent instruction (The instructions need better pictures!) in two hours last evening. No problems.

I took the Yaris out on the freeway today for a little trip for about 1 1/2 hours driving time, on level ground, up one of the steeper grades on the local freeway (Cajon Pass for those of you that know the greater Los Angeles area), and it worked just fine. No complaints.

So even with all the "problems" initially in understanding the unit, caused by Brandon Distributing, I am very satisfied now that it is in and working. Again I bought it through M&R Electronics on the Internet. I recommend them.

This happily ends the pursuit of a cruise control installation in a 2007 Toyota Yaris Hatchback with auto. Bye!

Thanks for all your research, I was considering getting a Yaris but the cruise control issue bothered me. Now I know there is a remedy!:-)

It seems your all talking about the cruise control with automatic transmission. Did anybody install with the five-speed.

LDBennett, I also live in Victorville, California and was wondering if the guy who installed your cruise control can install mine?

I can of course pay for his work.

LDBennett,

Thank you so much for all of your research I am looking into the Yaris hatchback and really like it but it was a deal breaker that it did not have cruise control. I have a dealership here in Vegas trying to sell me the Yaris S hatchback which he swears has cruise controll in it for 17,749.25. Now I can look into less expensive models and still get my cruise control.

Thank you again so very much

Does anyone know if the Rostra cruise control will work on the new 2008 Yaris Sport Hatchback?

The Yaris sport liftback is the same mechanically as the base model. It's just more expensive and has a spoiler and other lame superficial add-ons for people who think they are unique.

Hi, You mentioned a big manual for the Yaris you found on the internet. Would you happen to have that link? Would be greatly apreciated.

I live in Tulare, CA, and I purchased a 2008 Yaris hatchback from the Visalia, CA Toyota dealership...to have a cruise control installed withing 7 to 10 days after taking delivery of the car. I'm still waiting for that install. They've not yet fulfilled their agreement in the contract. So, today I called them and left a message...of course no one could take my call...that I want my money that I paid for the cruise control...that's $600!
Now...having read the information so graciously posted here...I've decided to just live with the car as it is...after getting used to commuting in it for two hours every day, it would probably seem strange now if I did have cruise control.

I bought a used 2007 Yaris auto hatchback here in Canada - they fitted the after market cruise control which they said was a genuine Toyota part, a lie of course.

Last week, I broke down - cause, the cruise control unit blew the throttle sensor! Suddenly, no drive and I had to be towed to the nearest Toyota dealer - this is the second unit they have fitted - the dealer I was towed to told me all about the problems with the after market cruise control unit - basically my yaris is not fitted with the wiring for cruise control, this was done from the 2009 model onwards - so any unit fitted with an after market part will invalidate your warranty - it might work but in my case the cruise was so bad it gave a surge which blew the throttle sensor - when the dealer tried to hook it back up, he said the car was just bucking a like a bronco so he left it disconnected so I could get home.

Now I am giving the yaris back and going with a model that has Toyota cruise aldready fitted i.e. a Corrolla or Matrix. So, beware all those fitting after market cruise parts on the yaris, it might work for a while but the car was not designed for it and it is not reliable.
