WARNING: This page is about a different car, the 2003 Nissan Altima. However, it is still accessible from the selected car via links, so may be relevant.

Power is supplied at all times:

Through 40A fusible link (letter m , located in the fuse and fusible link box)
To ignition switch terminal B.
With the ignition switch in the START position, power is supplied:
From ignition switch terminal St.
To intelligent power distribution module engine room (IPDM E/R) terminal 11.
With the ignition switch in the ON or START position, power is supplied:
Through 10A fuse [No. 12, located in the fuse block (J/B)]
To intelligent power distribution module engine room (IPDM E/R) terminal 43.
Ground is supplied, with the selector lever in the P or N position:
To intelligent power distribution module engine room (IPDM E/R) terminal 46
Through park/neutral position switch.
From ignition switch terminal St.

To terminal S of the starter motor windings.
The starter motor plunger closes and provides a closed circuit between the battery and the starter motor. The starter motor is grounded to the cylinder block. With power and ground supplied, the starter motor operates. In the event that the CAN communication line fails, the IPDM E/R will continue to receive a starter relay on signal from the BCM as long as the ignition switch remains in the START or ON positions.
