remote controller ID codes is attempted,
the oldest remote controller ID code will be
erased and that inputted after the fourth
one will be registered.
• When keyless start control module which
was used in another vehicle has been
installed, register the ID code of the remote
controller to the keyless start control
module first and then the following code.
