Headlamp (Hi) Circuit: Description

The IPDM E/R (intelligent power distribution module engine room) controls the headlamp high relay based on inputs from the BCM via the CAN communication lines. When the headlamp high relay is energized, power flows through fuses 34 and 35, located in the IPDM E/R.

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

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