System Description
INFOID:0000000004201450
Control of the headlamp system is dependent upon the position of the lighting switch (combination switch).
When the lighting switch is placed in the 2nd position, the BCM (body control module) receives input request-
ing the headlamps and park lamps to illuminate. This input 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 headlamp high and headlamp low relay coils. When energized, these
relays direct power to the respective headlamps, which then illuminate.
