It's like taking the cmos battery out of a motherboard to reboot the bios back to factory settings after a failed overclock.

I know I am always rebooting my windows PC, I never knew you had to reboot your vehicle! Thanks for the info might come in handy some day.

I recently experienced the same problem with the CD player/changer in my wife's Escalade. After having the car in the shop for front strut replacement, the CD player wouldn't play CDs, and worse, the CD player motor wouldn't stop running even after the car was off and the keys removed. My worst fear was having to replace out of warranty the whole integrated CD/DVD changer, navigation system to the tune of untold $$. When I told my mechanic, he went immediatly to the fuse panel and pulled the fuse. Then he put it back and everything worked again good as new.

Often times a simple battery disconnect will "reset" the OBD system.  But if there are any significant warnings they will reappear from the memory that didn't get erased.  Sometimes 40 to 60 engine starts will erase error messages too.  If the computer doesn't receive the signal it took to trigger the error code during this time period.

Agree it's an interesting post.  I've had two rental vehicles (different manufacturers) where the transmission just suddenly disengaged and the gas pedal stopped working.  What finally got the vehicles in gear again was cycling the ignition key.  Must be using a Windows operating system... ;-)  In all seriousness, I think vehicles are getting too complicated to be reliable in the long term.  I don't want my car to be like Microsoft Office where they have piled in more and more distracting "features" which offer fertile ground for introduction of more bugs without fixing bugs I first ran across a decade ago...

I've had experienced mechanics mention to me several times that disconnecting the battery and also shorting out the disconencted battery cables for about a minute (to ensure complete reset and that non-volatile memory is cleared) is a good practice for oddball electrical & control system behaviors.

This is a fascinating post.  In my wildest dreams I would never have thought a "horseless" carriage might need rebooting to correct issues with electrical equipment.  I'm a mechanical engineer and just don't think along these lines.  QUESTION: Since this seems to be one solution to several problems, do any of the manufacturers provide "re-set" switches to allow for the reboot process?  I have two older vehicles and there is certainly nothing in the use and care manuals to indicating rebooting might be necessary.  Just checked both to verify.

That's certainly a good possibility.  However, I suspect that in general, a significant battery disconnect time will pretty much reset any sensors.  If the trigger conditions still exist, the sensor would trigger again eventually; if not, no harm, no foul!
