PINPOINT TEST A: ALL DOOR LOCKS ARE INOPERATIVE FROM ONE SWITCH

Normal Operation
The smart junction box (SJB) monitors circuits CPL42 (GY/YE) and CPL43 (VT/GY) for a ground signal. If the door lock control switch connects circuit CPL42 (GY/YE) to ground circuit GD161 (BK/YE) or circuit GD175 (BK/BU) the doors lock. If the door lock control switch connects circuit CPL43 (VT/GY) to the ground circuit GD161 (BK/YE) or circuit GD175 (BK/BU) the doors unlock.
