Headlamp (Lo) Circuit: Description

The IPDM E/R (intelligent power distribution module engine room) controls the headlamp low relay based on inputs from the BCM via the CAN communication lines. When the headlamp low relay is energized, power flows through fuses 40 and 41, located in the IPDM E/R.

(For USA) power then flows to the front combination lamp LH and RH low beams.

(For Canada) power then flows to the front combination lamp LH low beam and the daytime running light relay 2 which becomes energized and then power is sent to the front combination lamp RH low beam.
