System Description: Notes

Control of illumination lamps operation is dependent upon the position of lighting switch (combination switch). When lighting switch is placed in 1ST or 2ND position (or if auto light system is activated) BCM (body control module) receives input signal requesting illumination lamps to illuminate. This input signal is communicated to IPDM E/R (intelligent power distribution module engine room) across CAN communication lines. CPU (central processing unit) of IPDM E/R (intelligent power distribution module engine room) controls tail lamp relay coil. This relay, when energized, directs power to illumination lamps, which then illuminate.

Power is supplied at all times

To tail lamp relay [located in IPDM E/R (intelligent power distribution module engine room)]
Through 10A fuse [No. 71, located in IPDM E/R (intelligent power distribution module engine room)].

Power is also supplied at all times
