Unlock (Transmitter) Driver's Door

When an unlock command is received from the transmitter, the BCM provides battery voltage through circuit 1391 to the driver door UNLOCK relay in the RIPFB. The UNLOCK relay coil, grounded by circuit 450, energizes and causes the relay contacts to close. When the contacts close, battery voltage is provided through the LOCKS fuse, through the relay, and out the RIPFB to the driver door motor.

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.
