Circuit-System circuit diagram

System summarization
z Current is provided by battery, and it goes the F/L 0 fuse inside of chassis fuse box, fuse F/L2, and fuse F13 inside
of body fuse box to the controller of central control lock, so as to lock and unlock the door lock.
Operation of door lock
z The switch of left door lock will be closed when the left door lock button is pressed down by the driver. Pin No. 6
of controller of central control lock to pin No. 1 of left front door lock; to pin No. 2 of left front door lock to
ground through left door lock switch and generates a grounding signal. There is grounding signal input to
controller of central control lock, so it can confirm the left door is at locked state. The current goes through pin
No. 4 of controller of central control lock to pin No. 1 of right front door lock; through the motor to pin No. 2 of
right front door lock and pin No. 2 of controller of central control lock; the motor is electrified and runs forward
and right front door is locked.
z The switch of left door lock will be open when the left door lock button is lifted up by the driver. Pin No. 6 of
controller of central control lock can not form a return circuit so there will be no grounding signal produced. There
is no grounding signal input to controller of central control lock, so it can confirm the left door is at open position.
The current goes through pin No. 2 of controller of central control lock to pin No. 2 of right front door lock;
through the motor to pin No. 1of right front door lock and pin No. 4 of controller of central control lock; the motor
is electrified and runs reversal and right front door is opened.
Service hint
z B035 Controller of central control lock
3-grounding: the voltage is about 24V.
4-grounding: the moment voltage is about 24V when the left door lock button is pressed down.
2-grounding: the moment voltage is about 24V when the left door lock button is lifted up.
z D005 Right front door lock
1-grounding: the moment voltage is about 24V when the left door lock button is pressed down.
2-grounding: the moment voltage is about 24V when the left door lock button is lifted up.
61 z E005 Left front door lock
1-2: Contacts will be closed when the left door lock button is pressed down and the resistance is about 0 Ω.
Contacts will be disconnected when the left door lock button is lifted up and the resistance is about ∞ Ω.
