How to disable traction control on the Lexus CT200h

We had a new Lexus CT200h come in for dyno testing and ran into a problem. The traction control was engaging not allowing the car to drive on the dyno. This was caused by the rear wheel speed sensors showing a disproportionate (or in this case zero) speed compared to the front wheels. No problem off to the internet for a solution! Hmm no solution on the internet....dammit! Well good news for me and now for you my resources go much further than forum land. So just in time for winter I present to you how to engage the Lexus CT200h into Certification Mode (which disables the traction control I believe for smog testing).

Do with this what you will I assume no responsibility for your actions or any actions taken against you by Lexus or Toyota Motor Corporation.

Step 1. With your foot off the brake press the power button on
Step 2. Make sure the vehicle transmission is in Park setting
Step 3. Press the accelerator pedal completely to the floor and then fully release three times.
Step 4. Press and hold brake pedal
Step 5. Engage transmission into Neutral setting
Step 6. Release brake pedal
Step 7. Press the accelerator pedal completely to the floor and then fully release three times
Step 8. Press and hold brake pedal
Step 9. Engage transmission into Park setting
Step 10. Press the accelerator pedal completely to the floor and then fully release three times
Step 11. In the lower right corner of the instrument cluster you should see ii display Certification Mode

I forgot to take a picture of the dash to show it in certification mode but I made this one just to show you where it will be located. Also note it is not displayed continuously it pops up intermittently. But once displayed it is engaged.

To return to normal all you have to do is turn the car off fully. The next time you start the vehicle the traction control will begin functioning normally. That's it! If I remember correctly the traction control light and ABS lights will also come on once you begin driving. These will also go away after driving a couple miles after returning the car to normal.
