My VX manual shows DTC P0705 Transmission Range Switch
(Mode Switch) Illegal Position . . . . . . . . . . . . 7A1 30

First thing I'd check is the 15A fuse (CB 15) in the engine compartment. According to the manual "This fuse can burn due to a short circuit in the backup lamp." Does your back up light come on?

Also, Tom's toad mode has the rear drive shaft disconnected which is why his odometer doesn't advance while being towed.
