and sold only in Japan
. says wiki , so i cant help .
did you read the FSM? yet, buy it.
if not you will fail. (100 % sure there)
IMMO are not just swapped like light bulbs.
if you know that, then same answer. why not look a the FSm
if you read the FSM it says i a nutshell for most IMMO
only the dealer can marry them back up.
they must be sync'd up.
call your dealer and ask this.
or go to japan.toyota.com (get URL in JAPAN)
and look at the PARTS page, and See every part on car.
including PCM./BCM and IMMO.
keep in mind most cars think its thief swapping IMMO to steal car.
so wont let him/her.
on my car, as soon as it sees the wrong VIN, bam, your dead.
im not sure how 2001 does this but it does. in some way.
and in most cases lots of ways...
i hope im wrong and the japan car, brains are dumb. but i bet not.
