TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

Details of time display
CRNT: Displays when there is a malfunction now or after returning to the normal condition until turning igni-
tion switch OFF → ON again.
PAST: Displays when there is a malfunction that is detected in the past and stored.
1 - 39: Displayed if any previous malfunction is present when current condition is normal. It increases like 1
→ 2 → 3...38 → 39 after returning to the normal condition whenever ignition switch OFF → ON. The counter
remains at 39 even if the number of cycles exceeds it. It is counted from 1 again when turning ignition switch
OFF → ON after returning to the normal condition if the malfunction is detected again.

Component DescriptionINFOID:0000000001527651
Part Description
BCM• Monitors the combination switch position.
Requests the IPDM E/R (via CAN communication lines) to actuate the headlamp
high and low relays based on combination switch position .
Requests the combination meter (via CAN communication lines) to turn the high
beam indicator lamp ON.
IPDM E/RControls the integrated headlamp high and low relays based on input from the BCM
over the CAN communication lines.
Combination switch
(Lighting & turn signal switch)Refer to BCS-9, "
System Description".
Combination meter
(High beam indicator lamp)Controls the high beam indicator lamp ON during high beam operation based on input
from the BCM over the CAN communication lines.
Headlamp assem-
blyHID control unit Controls electricity flow through the xenon bulb.
Xenon bulbUses two tungsten electrodes and is filled with xenon gas and other metal halides.
Electricity flows between the electrodes to illuminate.
High beam solenoid Actuates the mobile valve shade to control high and low beam operation.
Mobile valve shadeWhen actuated by the high beam solenoid, it shades light output from the xenon bulb
for low beam operation and opens to allow more light output during high beam opera-
tion.
