Unlock (Transmitter) Driver's Door
When an unlock command is received from the transmitter, the body control module provides battery voltage through circuit 694 to the driver door lock motor. The motor is grounded by circuit 295 going through the LOCK relay in the IPFB to ground through circuit 550.The Saturn Security System is disabled when the UNLOCK button is pressed. If the horn chirp mode is enabled, the horn will chirp twice for confirmation that the Saturn Security System is disarmed.
