How do you reset a computer on a Honda CR-V 2003?

Answer 1

UNLESS you are referring to the factory pre-set parameters (which cannot be re-programmed) - to remove all the computer's 'learned' shift setpoints, etc, or remove other stored codes, simply un-hook the battery cables for a short length of time - this will 'kill' all the stored information in ALL your on-board items - including the clock and your radio and any other electronics you may have that rely on the vehicles battery power.

CAUTION: If you have a 'security-type' radio make sure you know the code for gaining access to it once you restore the vehicle's battery pwer.
