SYSTEM DESCRIPTION

1. POWER DOOR LOCK CONTROL SYSTEM DESCRIPTION

(a) The power door lock system locks/unlocks all the

doors. The master switch and the door control switch on the passenger door send "lock/unlock" request signals to the main body ECU. Then, the main body ECU sends these request signals to the lock motors in each door to lock/unlock all the doors at once in response to the inputs. Operating the driver's door lock using a mechanical key sends request signals to lock/unlock the doors to the main body ECU via the master switch. "2-step unlock function" is optional for unlocking procedures of the key-linked lock for the driver side door.

DESCRIPTION

The driver's door unlock detection switch is built into the driver's door lock assembly. The switch turns on when the driver's door is locked and turns off when the door is unlocked. The main body ECU is connected to the driver's door lock assembly via terminal LSWD and driver's door lock/unlock state signals are input to the main body ECU. The main body ECU applies voltage to the door unlock detection switch via terminal LSWD. When the door unlock detection switch is on (there is continuity between the switch terminals), a lock st ate signal is input to the main body ECU. When the switch is off (there is no continuity between the switch terminals), an unlock state signal is input.
