Component Parts and Harness Connector LocationNKS003OK
System DescriptionNKS003OL
The control of the headlamp system operation is dependent upon the position of the combination switch (light-
ing switch). When the lighting switch is placed in the 2ND position, the BCM (body control module) receives
input signal requesting the headlamps (and tail lamps) 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) located in the IPDM E/R controls the headlamp high and headlamp low relay coils.
These relays, when energized, direct power to the respective headlamps, which then illuminate.
