for detailed installation location.
IPDM E/R
• Controls the integrated smart FET, and supplies voltage to the load according
to the request from BCM via CAN communication.
• The headlamp warning signal is input from the LED headlamp control module,
and the IPDM E/R requests the combination meter (CAN communication) to
display the headlamp warning.
• Judges the vehicle status from each signal in order to control the headlamp
aiming control.

OUTLINE
• Semiconductor device (Light emitting diode: LED), which is illuminated when forward bias electric voltage is
applied, is adopted as the source of light instead of halogen bulb or xenon bulb.
• Comparing to halogen headlamp or xenon headlamp, LED headlamp is electrically power saving, durable,
and is illuminated in the similar color to the sunlight. Bright, natural, and eye-friendly visibility can be
obtained.
PRECAUTIONS FOR TROUBLE DIAGNOSIS
Representative malfunction examples are; “Light does not turn ON”, “Light blinks”, and “Brightness is inade-
quate.” Such malfunctions, however, occasionally by occur LED control module malfunction or lamp case mal-
function. Specify the malfunctioning part with diagnosis procedure.
CAUTION:
• Never touch the harness, LED headlamp control module, the inside and metal part of lamp when
turning the headlamp ON or operating the lighting switch, for preventing electrical shock.
• Never work with wet hands, for preventing electrical shock.
• Never perform LED headlamp control module circuit diagnosis with a circuit tester or an equivalent.
• Temporarily install the headlamps on the vehicle. Always connect power supply to the connector
(vehicle side) when checking ON/OFF status.
BCM
• Detects each switch condition by the combination switch reading function.
• Exterior lamp ON/OFF is judged from each signal, and then a request is trans-
mitted to IPDM E/R (CAN communication) to turn each smart FET ON/OFF.
• It also transmits a request to the combination meter (CAN communication) to
turn indicator lamp and warning (information display/buzzer) ON/OFF.
• Blinks the turn signal lamp and hazard warning lamp according to the each
switch condition.
• Requests the turn signal indicator lamp blink to the combination meter via CAN
communication.
• Requests the turn signal operating sound ON to the combination meter via CAN
communication.
• Judges the vehicle status from each signal, and illuminates the stop lamp and
high-mounted stop lamp.
• Judges the vehicle status from each signal, and illuminates the rear fog lamp.
• Refer to
BCS-6, "BODY CONTROL SYSTEM : Component Parts Location"
for
detailed installation location.
Hazard switch
Refer to
Air bag diagnosis sensor unit
• When the air bag operates, a request is transmitted to BCM (CAN communica-
tion) to blinks the hazard warning lamp.
• Refer to
SRC-6, "Component Parts Location"
for detailed installation location.
Combination switch
Refer to
BCS-13, "COMBINATION SWITCH READING SYSTEM : System De-
Combination meter
• Turns the indicator lamp and warning (information display/buzzer) ON/OFF ac-
cording to the request from BCM via CAN communication.
• Turns the headlamp warning ON according to the request from IPDM E/R via
CAN communication.
• Blinks the turn signal indicator lamp and outputs the turn signal operating sound
with integrated buzzer according to the request from BCM via CAN communi-
cation.
• Combination meter transmits vehicle speed signal to BCM and IPDM E/R via
CAN communication.

• Disconnect the battery negative terminal before disconnecting the lamp socket connector or the har-
ness connector.
• Check for fusing of the fusible link(s), open around connector, short, disconnection if the symptom
is caused by electric error.
• Always check for deformation or hole of headlamp housing and engagement of bulb cover. Other-
wise, water may enter into headlamp because of damage of headlamp housing and contact to LED
headlamp control module connector. The normal operation may be inhibited when short circuit to
power supply is detected.
NOTE:
Turn the switch OFF once before turning ON, if the ON/OFF is inoperative.
FRONT COMBINATION LAMP : LED Headlamp Control Module
INFOID:0000000010788741
• LED headlamp control module is integrated in the front combina-
tion lamp and turns the LED headlamp ON according to the
request from IPDM E/R.
• Outputs the headlamp warning signal to the IPDM E/R.
FRONT COMBINATION LAMP : Headlamp Aiming Motor
INFOID:0000000010788742
• Headlamp aiming motor is integrated in the front combination
lamp.
• Headlamp aiming motor adjusts the headlamp light axis upward
and downward according to input drive signal from IPDM E/R.
Front Height Sensor
INFOID:0000000011008901
• Front height sensor is installed in transverse link.
• Front height sensor detects the vehicle front height deviation with
sensor lever, and transmits the detected value as a front height
sensor signal to IPDM E/R.

Rear Height Sensor
INFOID:0000000010788743
• Rear height sensor is installed in lower link.
• Rear height sensor detects the vehicle rear height deviation with
sensor lever, and transmits the detected value as a rear height
sensor signal to IPDM E/R.
Light & Rain Sensor
INFOID:0000000011008902
• The light & rain sensor detects the outside ambient light level, for-
ward light level and sensor conditions.
• Based on ambient light level (day/night detection), forward light
level (tunnel detection) and sensor conditions it judges ON/OFF
condition for exterior lamps.
• And it transmits exterior lamp ON/OFF request to the BCM by the
light & rain sensor serial link.
• BCM controls each function depending on the signals. And it
detects the light & rain sensor serial link error and the light & rain
sensor malfunction.
Hazard Switch
INFOID:0000000010788745
Inputs the hazard switch ON/OFF signal to BCM.
Stop Lamp Switch
INFOID:0000000010788746
• Stop lamp switch is installed to brake pedal bracket.
• BCM detects the brake pedal status from the ON/OFF signal that is
input from the switch.
