SYSTEM
HIGH BEAM OPERATION/FLASH-TO-PASS OPERATION
With the lighting switch in the 2nd position and placed in HIGH position, the BCM receives input requesting the
headlamp high beams to illuminate. The flash to pass f eature can be used any time and also sends a signal to
the BCM. This input is communicated to the IPDM E/R across the CAN communication lines. The CPU of the
combination meter controls the ON/OFF status off the HIGH BEAM indicator. The CPU of the IPDM E/R con-
trols the headlamp high relay coil which supplies power to the high beam headlamps.
The combination meter receives a high beam request signal (ON) through the CAN communication lines and
turns the high beam indicator lamp ON.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the headlamps remain illuminated fo r a period of time, unless the lighting switch position
is changed. If the lighting switch position is changed, then the headlamps are turned off.
AUTO LIGHT SYSTEM
AUTO LIGHT SYSTEM : System DiagramINFOID:0000000009463545
AUTO LIGHT SYSTEM : System DescriptionINFOID:0000000009463546
• BCM (Body Control Module) controls auto light operati on according to signals from optical sensor, lighting
switch and ignition switch.
• IPDM E/R (Intelligent Power Distribution Module Engine R oom) operates parking, license plate, tail, front fog
lamps and headlamps according to CAN communication signals from BCM.
• Optical sensor detects ambient brightness of 800 to 2,500 lux. And optical sensor converts light (lux) to volt-
age, then sends the optical sensor signal to BCM.
OUTLINE
The auto light control system has an optical sensor that detects outside brightness.
When the lighting switch is in AUTO position, it autom atically turns ON/OFF the parking, license plate, tail,
front fog lamps and headlamps in accordance with the am bient light. Sensitivity can be adjusted. For the
details of the setting, Refer to BCS-19, "HEADLAMP : CONSULT Function (BCM - HEADLAMP)"

TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal swit ch) is in LH or RH turn position with the ignition
switch in the ON position, the BCM receives input reques ting the turn RH or turn LH lamps to illuminate. The
BCM controls the turn signal power to the respective turn signal lamp. The BCM also sends a turn indicator
signal ON request via the CAN communication lines to the combination meter. The combination meter then
activates the appropriate turn signal indicator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in the ON position, the BC M receives input requesting the hazard lamps illuminate.
The BCM controls the turn signal power to both the LH and RH turn signal lamps. The BCM sends a hazard
indicator signal ON request via the CAN communication lines to the combination meter. The combination
meter then activates both the LH and RH turn signal indicators and audible buzzer.

PARKING, LICENSE PLATE AND TA IL LAMPS : System DescriptionINFOID:0000000009463554
PARKING, LICENSE PLATE AND TAIL LAMPS OPERATION
When the lighting switch is in 1st or 2nd position, BCM detects the LIGHTING SWITCH 1st or 2nd POSITION
ON. The BCM sends a parking light ON request via the CAN communication lines to the IPDM E/R. The IPDM
E/R then activates the tail lamp relay which sends power to the parking and instrument illumination circuits.
EXTERIOR LAMP BATTERY SAVER CONTROL
With the combination switch (lighting and turn signal switch) in the 1st or 2nd position and the ignition switch is
turned from ON or ACC to OFF, the battery saver feature is activated.
Under this condition, the exterior lamps remain illumi nated for a period of time unless the lighting switch posi-
tion is changed. If the lighting switch position is changed, then the exterior lamps are turned off.

Operation Procedure
CAUTION:
Do not start the engine.
NOTE:
When auto active test is performed with hood opened, sprinkle water on windshield before hand.
NOTE:
• If auto active test mode cannot be actuat ed, check door switch system. Refer to DLK-100,
"Component Function Check".
• When auto active test mode has to be cancelled halfway through test, turn ignition switch OFF.
1. Close the hood and lift the wiper arms from the windshield. (Prevent windshield damage due to wiper
operation)

Concept of auto active test
• IPDM E/R starts the auto active test with the door
switch signals transmitted by BCM via CAN communica-
tion. Therefore, the CAN communication line between IPDM E/R and BCM is considered normal if the auto
active test starts successfully.
• The auto active test facilitates troubleshooting if any systems controlled by IPDM E/R cannot be operated.
