Power Locks: Description and Operation

System Outline

The current always flows to TERMINAL 1 of the integration relay through the DOOR fuse.

1. Manual Lock Operation
When the door lock control SW or door key lock and unlock SW are operated to Lock position, a lock signal is input to TERMINAL (A) 9 or (A) 7 of the integration relay and causes the relay to function. The current flows from TERMINAL 1 of the relay to TERMINAL 2 to the door lock motors to TERMINALS (A) 1 and 3 of the relay to TERMINAL 9 to GROUND and the door lock motors locks the door.

2. Manual Unlock Operation
When the door lock control SW or door key lock and unlock SW are operated to Unlock position, an unlock signal is input to TERMINAL (A) 8, (A) 6 or (A) 5 of the integration relay and causes the relay to function. The current flows from TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND and the door lock motors unlocks the door.

3. Double Operation Unlock Operation
When the door key lock and unlock SW LH is turned to the unlock side, only the driver's door is unlocked. By turning the door key lock and unlock SW LH to the unlock side, a signal is input to TERMINAL (A) 6 of the relay, and if the signal is input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL 3 of the integration relay to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND, causing the door lock motors to operate and unlock the doors.

4. Ignition Key Reminder Operation
- Operating door lock knob (Operation of door lock motors)
With the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lock knob (Door lock motor), the door is locked once but each door is unlocked soon by the function of the relay. As a result, the current flows from TERMINAL 1 of the integration relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.

- Operating door lock control SW or door key lock and unlock SW
With the ignition key in the cylinder (Unlock warning SW on), when the door is opened and locked using door lock control SW or key SW, the door is locked once but each door is unlocked by the function of SW contained in motors, and the signal is input to TERMINAL (A) 19 of the relay. According to this input signal, the current flows from TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.

- In case of key less lock
With the ignition the key in the cylinder (Unlock warning SW on), when the unlock function is disturbed for example pushing the door lock knob etc., the door holds on lock condition. After closing the door, door courtesy SW inputs the signal into TERMINAL 5 or 6 or (A) 13 of the integration relay. By this input signal, the relay works and current flows from TERMINAL 1 of the relay to TERMINALS (A) 1 and 3 to the door lock motors to TERMINAL 2 of the relay to TERMINAL 9 to GROUND and unlocks all the doors.

5. Glass Hatch Open Operation
When the glass hatch opener SW on, the ignition SW at OFF position or the ignition SW at ON position and the vehicle speed is less than approx. 16 km/h (9.6 mph), the glass hatch is opened.
