HEADLAMP (LO) CIRCUIT

HEADLAMP (LO) CIRCUIT

Description

INFOID:0000000009694063

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.

(Without daytime light system) power then flows to the front combination lamp LH and RH low beams.

(With daytime light system) power then flows to the front combination lamp LH low beam and the daytime light

relay 2 which becomes energized and then power is sent to the front combination lamp RH low beam.

PARKING LAMP CIRCUIT

Description

INFOID:0000000009694066

The IPDM E/R (intelligent power distribution module engine room) controls the tail lamp relay based on inputs

from the BCM via the CAN communication lines. When the tail lamp relay is energized, power flows through

fuse 37, located in the IPDM E/R. Power then flows through the tail lamp relay to the front and rear combina-

tion lamps, license plate lamps.
