Anyone figure out a consistent way to enable and disable the ET mode yet?

engineering test mode can be entered by pressing and holding the "OK" button while starting the vehicle, and holding it until you see a little "ET" icon appear in the bottom-right corner of the dash

you can see various things, including testing all the dash lights, seeing current DTCs, changing the DTE estimate bias
