Unlock Input Circuit

Pressing a front power door lock switch to the UNLOCK position connects CKT 781 (ORN/BLK) through the switch to ground CKT 1250. CKT 781 (ORN/BLK) grounds the MALL module connector C2 terminal C6 in order to provide the door unlock input signal.

Pressing the door unlock button on the keyless entry transmitter causes the RFA module to ground terminal E5. With this action the RFA module grounds CKT 781 (ORN/BLK). In turn, CKT 781 (ORN/BLK) grounds the MALL module connector C2 terminal C6 in order to provide the door unlock input signal.
