CIRCUIT - SYSTEM SCHEMATIC DIAGRAM 61-59

System description:
The battery current is transmitted to the fuse F2 in the engine fuse box, and then to the pin
B6 of body control module connector C55 through the F1 in the internal fuse box, to supply
electric energy to the left front door unlock switch. 61
The battery current is transmitted to the fuses F28 and F13 in the engine fuse box, and
then to the pin B7 of body control module connector C55 to supply battery energy.
Central control signal
When the vehicle speed reaches a certain value, BCM will lock all doors automatically.
The left front central control lock pin 1 is earthed, and the pin 2 is for output to provide the
central control lock unlock/lock signal to D6 of the body control module connector C57.
Door lock signal
Locking:When the left front door is locked, the pin 4 of the left front door will be earthed,
and the pin 5 will output the signal to E30 of the body control module connector C58
to provide the locking signal.The output from the pin B1 of the body control module
connector C55 is divided into four ways.
a.To pin 6 of the left front door lock assembly, output from the left front door lock
assembly pin 7 through the door lock motor,then to the pin B3 of the body control
module connector C55 to lock the left front door.
b.To pin 3 of the right front door lock motor, output from the right front door lock
assembly pin 2 through the door lock motor, then to the pin B2 of the body control
module connector C55 to lock the right front door.
c.To pin 6 of the right front door lock motor, output from the left rear door lock
assembly pin 7 through the door lock motor, then to the pin B2 of the body control
module connector C55 to lock the left rear door.
d.To pin 3 of the right rear door lock motor, output from the right rear door lock
assembly pin 2 through the door lock motor, then to the pin B2 of the body control
module connector C55 to lock the right rear door.
Unlocking: Output from the pin B2 of the body control module connector C55 to the
right front door lock motor, right rear door lock motor and left rear door lock motor
respectively. Output from another terminal of the door lock motor to the pin B1 of
the body control module connector C55, to activate the right front door lock motor,
right rear door lock motor and left rear door lock motor respectively. The left front
door lock motor is unlocked in the following way: the current is output from the pin
B3 of the body control module connector C55 to the pin 7 of the left front door lock
assembly, and then to the pin B1 of the body control module connector C55 via the
pin 6 of left front door lock motor through the motor, thus to unlock the left front door
motor.
