HEADLAMP (LO) CIRCUIT
DescriptionINFOID:0000000012432807
The IPDM E/R (intelligent power distribution modul e engine room) controls the headlamp low relay based on
inputs from the BCM via the CAN communication li nes. When the headlamp low relay is energized, power
flows through fuses 40 and 41, located in the IPDM E/R.
(Without daytime running light system) power then flow s to the front combination lamp LH and RH low beams.
(With daytime running light system) power then flows to the front combination lamp LH low beam and the day-
time running light relay 2 which becomes energized and t hen power is sent to the front combination lamp RH
low beam.

PARKING LAMP CIRCUIT
DescriptionINFOID:0000000012432810
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.

COMPONENT PARTS
A. LH side of instrument panel B. Behind center of instrument panel C. Center of instrument panel
No. Component Description
1. BCM The BCM receives the fan ON and A/C ON signals from the front air control and sends a com-
pressor ON request to the ECM.
2. Fuse Block (J/B) Located in the passenger compartment, behind the left lower IP, the Fuse Block (J/B) con-
tains the front blower motor relay and several fuses required for the air conditioner control
system.
3. Blower relay The blower relay controls the flow of current to fuse 20, 21 and 22 in the Fuse Block (J/B).
The relay is connected directly to ground, and is energized when the ignition switch is in the
ON or START position.
4. Front blower motor The front blower motor varies the speed at which the air flows through the ventilation system.
5. Front blower motor resistor Ground for the blower is supplied through blower resistor and the blower speed switch. As
the switch is moved from position 1 through 4, more current is allowed to flow through the
motor, for a higher speed. This is because less resistors are in the path as the switch is
moved to a higher position. When the switch is on the highest position, all resistors are by-
passed.
6. Thermo control amp. Thermo control amp. is composed of thermistor and amplifier. When the A/C switch signal is
received from the front air control, the thermo control amp. transmits the A/C ON signal to the
BCM according to evaporator fin temperature. When the thermistor detecting temperature of
the air that passes through evaporator is extremely low, the thermo control amp. sends the
A/C OFF signal to BCM, and stops the compressor.
7. Front air control The front air control controls the operation of the A/C and heating system.
