down the driver side door latch, doors shall be
locked with the door lock signal output by locking
device; if you pull up the driver side door latch,

after a door lock signal output by locking device.
If you hold the latch switch, a door unlock signal is
output by locking device and then 3 unlock signals

(0sec.<T3<0.5sec.) after the latch switch is
pressed; at the same time, if latch switch is pulled
up, doors won ’ t be locked with an unlock signal
output.

lasting for T3 (5sec) in T2 (40msec), so the doors
are under unlocked status.
