71-52 WIRING - SYSTEM CIRCUIT DIAGRAM

Description:

• When the battery current flows from fuse F2 in the engine fuse box, via the interior
fuse box F1 to pin B6 of the body control module (BCM) connector C033, the front
left door release switch is powered.
The battery is powered when current flows from fuse F13 in the engine fuse box
to pin B7 of the BCM connector C033.

• Central control signal
When a certain of driving speed is reached, all doors are locked automatically.The
current is grounded at pin 11 of the front left power window switch and outputs from
pin 2, thus transmitting the central control lock signal to pin D6 of BCM connector
C035.

• Door lock signal
To lock: when the locking switch of the front left door lock assembly is on, pin 7is

grounded and a corresponding signal is output from pin 9to pin E28 of the BCM
connector C036, transmitting the locking signal. Signal output of pin B1 of BCM
connector C033 divides into four directions:
a. To pin 4of the front left door lock assembly, via the door lock motor, then sent
from pin 1of the assembly to pin B3 of BCM connector C033, the front left door is
locked.

b. To pin 2of the front right door lock assembly, via the door lock motor, then sent
from pin 1of the assembly to pin B2 of BCM connector C033, the front right door
is locked.
b. To pin 2of the rear left door lock assembly, via the door lock motor, then sent
from pin 1of the assembly to pin B2 of BCM connector C033, the rear left door is
locked.
b. To pin 2of the rear right door lock assembly, via the door lock motor, then sent
from pin 1of the assembly to pin B2 of BCM connector C033, the rear right door is
locked.

To release: when the release switch of the front left door lock assembly is on, pin
7is grounded and corresponding signals are sent from pin 10to pin E27 of BCM
connector C036, transmitting the release signal. The signal output from pin B2 of
BCM connector C033 are transmitted to pin 1of front right door lock motor, rear
right door lock motor and rear left door lock motor respectively. For the
high-frequency door lock motor, signals are sent from pin 2of the door lock motor
to pin B1 of BCM connector C033; then the front right door lock motor, rear right
door lock motor and rear left door lock motor will operate.
To release the front left door lock motor, signals are sent from pin B3 of BCM
connector C033 to pin 1of the front left door lock assembly via the motor. When
signals are transmitted from pin 2of the front left door lock motor to pin B1 of BCM
connector C033, the front left door lock motor is released.
