OPERATION
ETACS-ECU determines whether the shift position is
"P" or not according to the shift position signal sent by
A/T-ECU.

TECHNICAL DESCRIPTION (COMMENT)
If the doors are not unlocked when the selector lever
is shifted to the "P" position, a malfunction of the shift

position  signal  input  circuit(s)  or  ETACS-ECU  is
suspected. Also, the selector "P" position-linked door
unlock  function  may  have  been  "disabled"  with  the
customization function.
