System Diagram

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.
