Operation By Lighting Switch

WARNING: This page is about a different car, the 2007 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

With the lighting switch in the 1ST or 2ND position (or if the auto light system is activated), the BCM receives input signal requesting the parking, front side marker, license plate and tail lamps to illuminate. This input signal is communicated to the IPDM E/R across the CAN communication lines. The CPU in the IPDM E/R controls the tail lamp relay coil, which when energized, directs power

through 10A fuse (No. 37, located in the IPDM E/R)
through IPDM E/R terminal 57
to license plate lamp LH and RH terminal 1
to rear combination lamp LH and RH (tail/side marker) terminal 1, and
through 10A fuse (No. 36, located in the IPDM E/R)
through IPDM E/R terminals 28 and 49
to front side marker lamp LH and RH terminal 1
to front parking lamp LH and RH terminal 2.

Ground is supplied

to front side marker lamp LH and RH terminal 2
to front parking lamp LH and RH terminal 3
through grounds E9, E15 and E24, and
to license plate lamp LH and RH terminal 2
through grounds D406 and D504, and
to rear combination lamp LH (tail/side marker) terminal 5
through grounds B7 and B19, and
to rear combination lamp RH (tail/side marker) terminal 5
through grounds B117 and B132.

With power and ground supplied, the parking, side marker, license plate and tail lamps illuminate.
