Szerintem ez a lényeg:

"Unlocking a double-locked car

This action can only be initiated from the driver's door key lock. When the key is rotated CCW from its double-locked position, it releases the ground connection of the unlock inhibit microswitch. (Actually, once this is done, the trunk key lock can also be used to unlock the car.) As the key is rotated another =89 90=B0 CCW, it mechanically unlocks the door latch, raises the door lock button and moves the door lock linkage to a position that closes an unlock switch. The "UNLOCK" relay operates, and unlocks all doors. (During any UNLOCK relay operation, 12 volts is also applied to the second steering diode, which allows the double-lock motors to operate.) The current return path to ground from all lock and double-lock motors is via their connection to the (unenergized) LOCK relay NC contact to ground. The double lock motors operate quickly enough to also allow the door lock motors to operate."

 

Hajrá!
