11.9.3 System Working Principle
11.9.3.1 System Working Principle
Door Lock Switch
– System has two lock switches, one is located in the left front
door combination switch and the other is in the left front
door key cylinder. Other key cylinders can only be used to
unlock a single door and can not activate the central locking
function.
– The two lock switch locking signals input to the BCM share
a common input terminal, but the unlocking signal is input
individually.
Locking Operation
When the BCM receives locking input signal or the automatic
locking requirements are met, the BCM locking output terminal
will send power supply to control the door motor to lock four
doors. For hatchback model, the locking command is also sent
to the hatchback lock motor.
Unlocking Operation
When the BCM receives unlocking input signal or the automatic
unlocking requirements are met, the BCM unlocking output
terminal will send power supply to control the door motor to
unlock four doors. For hatchback model, the unlocking
command is also sent to the hatchback lock motor. (rear
compartment (hatchback) unlocks separately).
Super Locking (If Equipped)
On the vehicle with the super locking feature, in addition to door
lock there is also a super locking motor. If BCM receives the
super locking input signal, it will immediately send power from
the super locking output terminal to control the super locking
motor to activate super locking.
Note
Even on the vehicle with the super locking feature, the
rear compartment (hatchback) lock does not have the
super locking feature.
