TSB : Normal Operation

Details

The smart junction box (SJB) sends voltage reference signals to the RKE keypad through circuits 78 (LB/YE), 79 (LG/RD), 121 (YE/BK). When the buttons are pressed on the keypad, one or more of the signals are routed to ground through circuit 570 (BK/WH). Depending on the signals received, the SJB is able to determine which button is pressed. When a correct code has been entered, the SJB operates the locks accordingly.
