System Description: Notes

WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.

Control of the parking, license plate, and tail lamp operation is dependent upon the position of the lighting switch (combination switch). When the lighting switch is placed in the 1ST position, the BCM (body control module) receives input signal requesting the parking, license plate, side marker and tail lamps to illuminate. This input signal is communicated to the IPDM E/R (intelligent power distribution module engine room) across the CAN communication lines. The CPU (central processing unit) of the IPDM E/R controls the tail lamp relay coil. This relay, when energized, directs power to the parking, license plate and tail lamps, which then illuminate.

Power is supplied at all times

Through 15A fuse (No. 41, located in the IPDM E/R)
To tail lamp relay, located in the IPDM E/R, and
Through 15A fuse (No. 34 located in the IPDM E/R)

To ignition relay, located in the IPDM E/R, and
Through 50A fusible link (letter j , located in the fuse and fusible link box)
To BCM terminal 55, and
Through 15A fuse [No. 3, located in the fuse block (J/B)]
To BCM terminal 42.

With the ignition switch in the ON or START position, power is supplied
