Check to see if you have the two wires on the steering column for cruise (and the two cruise control icons on the cluster). If they are there, then you can do a real quick test by grounding the blue wire (with the ignition on) and the cruise control on icon should light up. If the wires aren't there, then you can check the voltage on the ECM pin 40. If there's 12V on that pin with the ignition on, then cruise is enabled, but just the wiring needs to be run.

Saggio- I put the two-switch DIY type on my '08 LB. I ran the wires from the clutch switch and ECM in through the AC drain grommet. I superglued a roller switch from Radio Shack onto the metal bracket beside the clutch pedal for use as a clutch switch. Everything works fine.

Hi, to everybody, In from Puerto Rico, Im glad that I found this great forum, full of great and interesting info about Yaris. I recently bought a used 2009 Toyota Yaris Sedan, and Im doing some great mods that I have found here in the forum, after reading for a while I decided to do the DIY Cruise Control mod on my sedan, it have oem power locks and power windows, all the wiring is in place, and the cluster have the CC symbols, I installed the oem stalk and wire, but when I tried to turn the Cruise control on, nothings happens. I swapped the stalk with the one in my wifes rav-4 and it didnt worked also, but the one I bought worked in the Rav-4, so the problem is not the stalk, or the wire. Is there any optional procedure or relay that I need to install?

Thanks in advance for your help, looking forward to see my Yaris with cruise.

Does it have an auto or manual transmission?

OK. I just noticed that you said that you have a 2009 Sedan and the wiring was in place. So, you had the blue and brown wires, not just the black horn wire on connector D3 (the one on the bottom of the steering column)?

magnum23 · 10-13-2010, 09:09 PM

Yes just double checked and it have the 3 wires in place.

OK - Just to triple check - We're talking about the connector next to the yellow one on the left side of this picture?

If that's good, look at the part number on the ECM (The silver box on the passenger side of the firewall) and post it. I don't know if anyone from PR has tried the cruise mod, and I think that you might get a different version of the ECM, from what we get here.

magnum23 · 10-13-2010, 09:32 PM

Yes that is good, mine is exactly as the picture you posted, where exactly is this part, (The silver box on the passenger side of the firewall)?

Pop the hood and look to the left:

OK - That's the same as my 09 LB, so the ECM is fine.

Do you have a volt meter and know how to use it?

magnum23 · 10-13-2010, 09:59 PM

I dont have one accesible right now? But why I should check? What do you think is the problem?

Thanks in advance.

Thanks in advance.

If you measure the voltage between the blue and brown wires (with the ignition in the on position) at the connector under the dash, you should see 12V. If you hold the on/off switch it should drop to 0V and then pop back to 12 when you release it. That's a good starting point.

Hey CTScott, can you take a look at this for me? Since Toyota Canada is "recommending" the Rostra CC units be removed for a full refund, I think I'd like to take the opportunity to install the OEM CC unit.

Here is a list of the parts I've compiled which I should need. It's for a Canadian 2008 AT.

Before I go ahead and order I'd like to make sure I'm ordering the right stuff!

Cheers
