spiff72 — It's also my understanding that when in 'N' all braking is done by the friction brakes — no regen.

greyghostTCH — In my TCH I can't force the ICE to start when in 'N,' but in either 'D' or 'B' it will start, as mentioned by nash, if the accelerator is pressed momentarily.

jbollt — I believe that, using Toyota's Intelligent Tester, the technician can indeed put the TCH into a test mode that allows all manner of things to be done that the driver cannot do! Things like running the ICE for troubleshooting, etc. The Repair Manual discusses this (offhand I can't say precisely where).
