Default Stupid Question

I have had had an ABS/TCS error for a while now. I finally bought a scan tool to read codes. It tells me that the right rear wheel sensor is bad. Oddly, I replaced this same one about 4 years ago.
To run complete diagnostics, my scanner says to put ignition into "ON" mode without the engine running.
I am drawing a blank.
If I hit the button, the engine starts.
Do I need to start it and stall it or is there another way?

Thanks in advance.

Press down on the ignition and hold for about 10 seconds, it'll be key on engine off.

Hold the bottom of the start button for about 5 seconds. When you hold this button for a second or so the car will be in accessory mode. When you hold it for longer, the car turns "on" without the engine running.

Curious. What scan tool are you using and we're you getting a CEL?
