Power Locks: Description and Operation

DOOR LOCK CONTROL

SYSTEM OUTLINE

Current always flows to TERMINAL 3 of the integration relay through the POWER fuse.

1. MANUAL LOCK OPERATION
To push the door lock control SW or door key look and unlock SW to LOCK position, a look signal is input to the integration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 13 to TERMINAL 2 of the door lock motors to TERMINAL 3 to TERMINAL 12 of the relay to TERMINAL 8 to GROUND and the door look motor causes the door to lock.

2. MANUAL UNLOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to UNLOCK position, an unlock signal is input to the integration relay and causes the relay to function. Current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door look motors to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and the door lock motor causes the door to unlock.

3. DOUBLE OPERATION UNLOCK OPERATION
When the door key lock and unlock SW LH is tuned to unlock position, only the front LH door is mechanically unlocked. Turning the door key lock and unlock SW LH to the unlock side causes a signal to be input to the relay, and if the signal is input again within 3 seconds by turning the door key look and unlock SW LH to the unlock side again, current flows from TERMINAL 12 of the integration relay to TERMINAL 3 of the door lock motors, TERMINAL 2 to TERMINAL 13 of the integration relay to TERMINAL 8 to GROUND, causing the door lock motors to operate and unlock the doors.

4. IGNITION KEY REMINDER OPERATION

- Operating door lock knob (In door lock motor operation)
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using door lock knob (Door lock motor), all doors are locked once but each door is unlocked soon by the function of the integration relay. As a result, current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.

- Operating door lock control SW or door key lock and unlock SW
With ignition key in cylinder (Unlock warning SW on), when any door is opened and locked using the door lock control SW or door key lock and unlock SW, all doors are locked once but each door is unlocked by the function of the SW contained in motor, which inputs the signal to the integration relay. According to this input signal, current flows from TERMINAL 3 of the relay to TERMINAL 12 to TERMINAL 3 of the door lock motors to TERMINAL 2 to TERMINAL 13 of the relay to TERMINAL 8 to GROUND and causes all the doors to unlock.
