The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on inputs from the BCM via CAN communication. When the headlamp low relay is energized, power flows through fuses 36 and 37, located in the IPDM E/R. Power then flows to the front combination lamps to the headlamp low beam.
