System Outline

Current always flows to TERMINAL 2 of the door lock control ECU through the POWER fuse.

1. MANUAL LOCK OPERATION
To push the door lock control SW or door key lock and unlock SW to LOCK position, a lock signal is input to TERMINAL 4 of the door lock control ECU and causes the ECU to function. Current flows from the POWER fuse to TERMINAL 2 of the ECU to TERMINALS 6 to TERMINALS 7 (LH), 6 (RH) of the door lock motors to TERMINALS 3 (LH), 2 (RH) to TERMINAL 1 of the ECU to TERMINAL 11 to GROUND and the door lock 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 TERMINAL 3 or 10 of the door lock control ECU and causes the ECU to function. Current flows from TERMINAL 2 of the ECU to TERMINAL 1 to TERMINALS 3 (LH), 2 (RH) of the door lock motors to TERMINALS 7 (LH), 6 (RH) to TERMINAL 6 of the ECU to TERMINAL 11 to GROUND and the door lock motor causes the door to unlock.

3. IGNITION KEY REMINDER OPERATION
* Operating the door lock knob (in door lock motor operation)
With the ignition key in cylinder (Unlock warning SW ON), when the door is opened and locked using the door lock knob (Door lock motor), the door is locked once but each door is unlocked soon by the door lock knob (Door lock motor), the current flows from TERMINAL 2 of the ECU to TERMINAL 1 to TERMINALS 3 (LH), 2 (RH) of the door lock motors to TERMINALS 7 (LH), 6 (RH) to TERMINAL 6 of the ECU to TERMINAL 11 to GROUND and causes all the doors to unlock.

* Operation the door lock control SW or door key lock and unlock SW
With the ignition key in cylinder (Unlock warning SW ON), when the door is opened and locked using the door lock control SW or door key lock and unlock SW. The door lock is locked once by each door is unlocked by the function of SW contained in motor, which the signal is input to TERMINAL 9 or 12 of the ECU. According to this input signal, the current in ECU flows from TERMINAL 2 of the ECU to TERMINAL 1 to TERMINALS 3 (LH), 2 (RH) of the door lock motors to TERMINALS 7 (LH), 6 (RH) to TERMINAL 6 of the ECU to TERMINAL 11 to GROUND and causes all the door to unlock.
