- through grounds M30 and M66.
Then front door key cylinder switch (driver side) operation signal (lock) is sent
- to BCM terminal 22
- from power window main switch (door lock and unlock switch) terminal 14
When the door is unlocked with front door key cylinder switch (driver side), ground is supplied
- to CPU of power window main switch
- through power window main switch (door lock and unlock switch) terminal 6
- through front door key cylinder switch (driver side) terminals 3 and 2
- through grounds M30 and M66.
Then front door key cylinder switch (driver side) operation signal (unlock) is sent
- to BCM terminal 22
- from power window main switch (door lock and unlock switch) terminal 14
BCM is connected to power window main switch and power window sub-switch as serial link.

- through front door switch driver side case ground.
When the front door switch passenger side is ON (door is OPEN), ground is supplied
- to BCM terminal 12
- through front door switch passenger side terminal 1 and
- through front door switch passenger side case ground.
When the rear door switch LH is ON (door is OPEN), ground is supplied
- to BCM terminal 63
- through rear door switch LH terminal 1 and
- through rear door switch LH case ground.
When the rear door switch RH is ON (door is OPEN), ground is supplied
- to BCM terminal 13
- through front door switch RH terminal 1 and
- through rear door switch RH case ground.
FUEL LID OPERATION
When door is unlocked with power window main switch (door lock and unlock switch), fuel lid lock actuator is unlocked. Ground is supplied
- to BCM terminal 44
- through fuel lid lock actuator terminals 1 and 2
- through passenger side select unlock relay 4 and 3 (With Intelligent Key)
- through BCM terminal 50.
In this condition, fuel lid can be opened if it is pushed.
OUTLINE
Functions Available by Operating the Door Lock and Unlock Switches on Driver's Door and Passenger's Door
- Interlocked with the locking operation of door lock and unlock switch, door lock actuators of all doors and fuel lid lock actuator are locked.
- Interlocked with the unlocking operation of door lock and unlock switch, door lock actuators of all doors and fuel lid lock actuator are unlocked.
Functions Available by Operating the Key Cylinder Switch on Driver's
- Interlocked with the locking operation of door key cylinder, door lock actuators of all doors and fuel lid lock actuator are locked.
Select Unlock Operation

CAN Communication System Description
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.
