1. Push the clutch pedal
2. Pull the handbrake (hold it)
3. Start engine
4. 2x foot break (at the second hold the break)
5. Handbrake: open – pull – open – pull
6. again 2x foot brake, but this time do NOT hold it)
Then should turn on the VSC and TRC lights.
i have a yaris TS with keylessGO… i don´t know how it is at the normal with key. and i also don´t know how it is at the automatic yaris…..
please just test it. at the automatic yaris i think you must not push the clutch pedal from #1 (hahahahah, because someone has stolen it)
to active the VSC and TRC just restart the engine.
