The current always flows to TERMINAL 1 of the door lock control relay through the D/L 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 toTERMINAL 18 or 20 of the door lock control relay and causes the door lock control relay to function. The current flows fromTERMINAL 1 of the door lock control relay to TERMINAL 2 to the door lock motors to TERMINALS 3 and 11 of the door lockcontrol relay to TERMINAL 12 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 inputto TERMINAL 19, 21 or 22 of the door lock control relay and causes the door lock control relay to function. The current flowsfrom TERMINAL 1 of the door lock control relay to TERMINALS 3 and 11 to the door lock motors to TERMINAL 2 of the doorlock control relay to TERMINAL 12 to GROUND and the door lock motors unlocks the door.
3. Double Operation Unlock Operation
When the door key lock and unlock SW front LH is turned to the unlock side, only the driver’s door is unlocked. By turningthe door key lock and unlock SW front LH to the unlock side, a signal is input to TERMINAL 21 of the door lock control relay,and if the signal is input again within 3 seconds by turning the SW to the unlock side again, current flows from TERMINAL 11of the door lock control relay to the door lock motors to TERMINAL 2 of the door lock control relay to TERMINAL 12 toGROUND, causing all the other doors are unlocked.
