  1. The project was successfully completed last year without an engine change. This was a 2017 GCC Yaris and the wiring in the dash and instrument cluster lamps were already fitted for CC. The changes needed were a CC stalk and new clock spring assembly on the steering column with the extra pins (which actually did come from a Corolla) and the ECU which was changed from an 89661-0U270 to 89661-0U350.
  2. Did you check the 12 pin connector underneath to see if pins 1 and 2 are installed in the loom going back to the ECU? Do they have any volts if you were to measure them with a multimeter? The reason I ask is that all these variations often use common parts, which might mean that there could be some version of your vehicle (maybe under a different name or body style or badge even) that uses the same engine / gearbox combination with a cruise control. If there is no wiring installed or there are no volts on the pins, then it is very doubtful.
  3. It might still be worth the OP checking out Pins 1 and 2 on that 12 pin Clock Spring connector below the steering column. If they are present, short them together momentarily with the engine running and see if any lights come on the instrument cluster.
  4. I am wondering Is there any combination of the engine and gearbox (item 3 and 5)? Perhaps a G spec model (item 4)? Even if a different basic model code?
  5. What is the engine and gearbox? Mine which used the 0U270 originally, replaced with the 0U350 is the 1NRFE engine and CVT gearbox. The information should be on the inside of the drivers door.
  6. Yes. I bought mine from here: https://www.obdii365.com/wholesale/vxdiag-vcx-nano-for-toyota-tis-techstream-compatible-with-sae-j2534.html The software is a cracked copy, the current links are on their website but it ships with a CD.
  7. Have you been able to connect Techstream to the OBD port... and see what data you have in the cruise control pages? It should be populated similar to the above. If not, you will need to find another ECU with cruise that is compatible with your engine and gearbox. @flash22 might be able to help find one.
  8. See the small connector on the right - it should have 4 pins inside it. The connector at the bottom should have 12 pins inside it.
  9. From the picture it looks like you might need to replace the clock spring as the connector for the CC stalk looks like it has no pins in it. The picture is a bit fuzzy though, so hard to tell. The instrument cluster looks similar to mine. The connector should look like the pictures below: On the underside of the dash, the white connector plugs into the other end of the clockspring. The wiring loom for the cc control should include the red and brown wires shown (although the colour code may vary by model). You could use a test switch or use a couple of small pieces of tinned copper wire to momentarily short those two pins to see if the CC light comes on and off when the engine is running. Also you could measure the voltage across them to see if they go all the way back to the ECU. If you have those wires installed, but the CC light does not activate, then you need to look at the engine ECU. It should be behind the passenger glove box under the dash. I have added a picture of the location of mine. What is the part number?
  10. If you go through my earlier posts you will find pictures. The stalk connects to a connector under the airbag in the steering wheel. This connector typically has other pins which connect to the horn button and possibly steering wheel audio controls, as well as a separate bright orange connector on a yellow lead for the airbag. The connector is part of a unit called a "spiral loom" or "clockspring" which basically allows for the rotation of the steering wheel. Basic models may have a clockspring fitted which does not have enough pins for the CC control as was the case with me. I found a suitable one from a breakers yard (from a Toyota Corolla) which was compatible. You have to remove the steering wheel to replace it and also be aware there will probably be a steering wheel angle sensor clipped behind it. Do not make the mistake of removing it and refitting it in the wrong position like I did. If you are lucky, your replacement part will come with an angle sensor already attached. Keep it that way and it should work, although you may need to do an steering angle reset which can be done with tech stream or a paper clip if you want to google it. Once you have the clockspring sorted, you need to find the loom under the dashboard that goes between the clockspring and the ECU. I was lucky enough that all the wiring was present, but check the pin numbers on my earlier posts. Also I was lucky that the instrument panel already had the correct LEDs fitted for the cruise control indications. But again YMMV. Finally, the ECU must support Cruise Control. If it doesn't you will have to find a replacement ECU which supports the same engine and gearbox combination for a higher spec model which does have cruise control. Sadly I had to buy a new one from Toyota which wasn't cheap, but I was able to fit it myself as a drop-in replacement and use techstream to program the VIN. If you're lucky your ECU will just work, or you might find one at a breaker's yard. Hope that helps.
  11. The unit you show is probably capable of reading the ECU, but I am not sure if it will reprogram it unless it is SAE J2534 compatible. I note that the cable you have shown says it is, but it is also described as a "diagnostic tool" which you might find is "read only". As I was buying a replacement ECU, I had to reprogram the VIN and potentially the keys, (although on my particular model it turned out the keys did not need reprogramming). Anyway, I had to ask the question to the support guys at obdii365.com who were helpful (although their English was a bit hit and miss). They recommended a different programmer so I can only speak from my experience, to say that the one i bought worked for me. https://www.obdii365.com/wholesale/vxdiag-vcx-nano-for-toyota-tis-techstream-compatible-with-sae-j2534.html If I were you, I would get in touch with them and explain what you are trying to do. From my earlier post at the top of this page... The "cracked" version of Techstream Global which I downloaded from: https://www.obdii365.com/wholesale/mini-vci-for-toyota-with-toyota-tis.html ...did program the VIN. The USB communication interface I used is the VCX Nano, VXDIAG (powered for TIS) which is SAE J2534 compatible for reprogramming. It was also capable of registering the transponder for the keys.
  12. Personally, I wouldn't buy anything from Ali Express, having been ripped off when I bought the CC lever from one of their suppliers and ended up with a poster instead, which they refused to refund. I bought my kit direct from https://www.obdii365.com If you have to press the clutch pedal to start it, then yes you have a switch.
  13. Hi F117. Have a good read through these posts and it should guide you towards the things you need to check. I note you have audio controls on your steering wheel, which would suggest the clock spring will support a CC connector. However, you will need to check what wiring you have between the clock spring and the ECU behind the dashboard. My early posts show the connector underneath the clock spring after removing the steering column plastic clamshell. If the wiring exists you need to check the voltages on the pins to see if it goes all the way to the ECU. Your instrument cluster may or may not have the LEDs fitted for the CC active indications. I was lucky, but you need to check your specific vehicle. As your vehicle is a manual, you also need to see if a clutch pedal switch is fitted and wired in. I would suspect not if your car does not have CC as standard. There are a number of YouTube videos you can search for which deal with fitting this switch. Ultimately, you might also have to change the ECU for a compatible type which will support CC as I did. Unless you can find one in a breaker's yard, this is likely to be a costly item from the dealer. Lastly, the precise sequence you follow will depend on your specific vehicle type and as yours is a very different engine/transmission combination to mine, it would probably be worth your while to start a new thread on this forum and document each step, so any advice will be specific for your vehicle.
