ON-VEHICLE INSPECTION
1.CHECK SHIFT LOCK OPERATION
a. Move the shift lever to the P position.
b. Turn the ignition switch to the LOCK position.
c. Check that the shift lever cannot be moved to any position other than P.
d. Turn the ignition switch to the ON position, depress the brake pedal and check that the shift lever
can be moved to another position.

1.GENERAL
When the front and rear door system detects that the front and rear doors are ajar, it automatically
actuates the motor to fully close the front and rear doors.
Position detection switches are provided in the door closer mechanism in each of the front and rear
doors' lock assemblies to detect whether the front and rear doors are open, closed or ajar. If a
detection signal that indicates that a front or rear door is ajar is transmitted to the door ECU, the
door ECU actuates the door closer motor to fully close the door.
In this system, each door is independently controlled by the door ECU inside each door. The door
ECUs, which communicate via the BEAN, belong to the door bus.
A mechanical cancel mechanism is provided. This mechanism enables the front and rear doors to
be opened by operating either the outside or inside door handle while the door closer system is
operating. Through the function of the link and the lever that move together with the movement of
the door handle, the mechanical cancel mechanism cuts off the transmission of power from the
motor and disables the operation of the door closer system, thus enabling the door to be opened.
If the operation of the door close system is not completed within approximately 3 seconds (a
foreign object is jammed in window, for example), the door ECU will interpret it as a malfunction
and stop applying the current to the motor.
2.FUNCTION OF COMPONENT
The close system consists mainly of a door closer assembly and the door ECU. Each door closer assembly
contains a switch and a motor. The components' functions are listed in the table below.
