Sorry for the stupid questions, but could anybody clarify the below for me?
Is this step done with or without holding down the brake pedal?
Is this one click/notch from the complete up/off position, or one click/notch from the rest position?
Is this one click/notch from the complete up/off position, or one click/notch from the rest position?

No prob! After my dealer spent 45 mins trying to figure it out I figured if give it a go before I found the video. After a few drinks and the neighbors looking at me screaming to myself in the car I got it working.

Works great on a 2017 IS 300 F-sport. I had to try it 4 times and it finally worked.
Please note, the last step is to actuate the left turn signal. It should actually read left change lane. Don't do a full two clicks down, just do the one click like you were going to change lanes. Also, setting the flasher count with the intermittent wiper control...even though I had mine set one from the bottom (for 5 flashes) I clicked through all of them and stopped on the second from the bottom before proceeding to the left lane change step.
Hope this helps if some of you were stuck.

this video works...but when you do the little test, before turning the car on, you need to lightly touch it down twice (not once as in the video). works great on my 2016 IS.

1.) Ignition off, doors closed
2.) Hold the wiper switch in the full up position. (this is the wiper off position)
3.) While holding the wiper switch in the full up position, turn the IG on. (two presses of the start/stop switch)
4.) Hold wiper switch in the full up position for 5 seconds
5.) Move the wiper switch down one "click" or "notch", hold for 5 seconds
6.) Move the wiper switch back to the full up position, hold for 5 seconds
7.) Move the wiper switch down one "click" or "notch". hold for 5 seconds (same position as step 5)
8.) Move the wiper switch back to the rest position (neutral)
If this was done correctly, the right turn signal will flash once.
To adjust how many flashes you want, you change the intermittent wiper speed switch. P1 starts with the speed switch all the way at the bottom, P4 will be the top speed. This is found on the wiper stalk.
P1: 3 blinks
P2: 5 blinks
P3: 7 blinks
P4: Function turned off
Set the intermittent wiper speed to the desired setting.
Use the Turn Signal stalk and push down like you want to activate the left turn signal, the flashers should activate
If the turn signal blinks once, you change it to the "3 flashes" setting
If the turn signal blinks twice, you changed it to the "5 flashes" setting
If the turn signal blinks three times, you changed it to the "7 flashes" setting
If the turn signal blinks four times, you turned the function off.
Once this is done, cycle the ignition switch off, and back on, and it should be changed.
