Operation

Exterior light warning light
1.  When the auto leveling control module/adaptive LED headlights control module or body control module (BCM) detects a malfunction with the ignition switched ON (engine off or on), it sends (1) any of the following signals to the instrument cluster via CAN communication.
―  Headlight auto leveling system non-initialization signal
―  Headlight auto leveling system malfunction signal
―  Exterior light malfunction signal
2.  The instrument cluster turns the transistor on (2) based on each signal.
3.  When the transistor turns on intermittently, the exterior light warning light flashes (3), and when the transistor is on continuously, the exterior light warning light turns on (3).

Exterior light warning indication
1.  The instrument cluster receives (1) the following signals from the auto leveling control module/adaptive LED headlights control module or body control module (BCM) via CAN communication with the ignition switched ON (engine off or on), it displays (2) the exterior light warning indication in the multi-information display.
―  Headlight auto leveling system non-initialization signal
―  Headlight auto leveling system malfunction signal
―  Exterior light malfunction signal

Turn Signal/Hazard Warning Indicator Lights


Purpose

•  The turn signal/hazard warning indicator lights notify the driver that the turn lights are flashing.


Function

•  When the instrument cluster receives a turn signal/hazard warning indicator lights on signal sent from the body control module (BCM) via CAN communication, it flashes the turn signal/hazard warning indicator lights.
Note
•  If a turn light is burned out, the turn signal/hazard warning indicator lights flashing speed increases.


Structure/Construction

•  The turn signal/hazard warning indicator lights are built into the instrument cluster.

Operation

Turn signal indicator light
1.  When the turn switch is in the LH or RH position, the instrument cluster sends (1) a turn switch LH signal or turn switch RH signal to the body control module (BCM) via CAN communication.
2.  When the body control module (BCM) receives the turn switch LH signal or turn switch RH signal with the ignition switched ON (engine off or on), it sends (2) the signal to the instrument cluster as a turn signal/hazard warning indicator lights on signal.
3.  The instrument cluster turns the transistor on (3) intermittently based on the turn signal/hazard warning indicator lights on signal.
4.  When the transistor turns on intermittently, the turn signal indicator light flashes (4).

Hazard warning indicator light
1.  When the hazard warning switch turns on, the climate control unit sends (1) a hazard warning switch on signal to the body control module (BCM) via CAN communication.
2.  When the body control module (BCM) receives the hazard warning switch on signal, it sends (2) the signal to the instrument cluster as a turn signal/hazard warning indicator lights on signal.
3.  The instrument cluster turns the transistor on (3) intermittently based on the turn signal/hazard warning indicator lights on signal.
4.  When the transistor turns on intermittently, the hazard warning indicator light flashes (4).

Lights-on Indicator Light/Lights-on Indication


Purpose

•  The lights-on indicator light/lights-on indication notifies the driver that the TNS (parking lights) is turned on.


Function

•  When the instrument cluster receives the lights-on indicator light on signal sent from the body control module (BCM) via CAN communication, it turns on/displays the lights-on indicator light/lights-on indication.


Structure/Construction

•  The lights-on indicator light is built into the instrument cluster.
•  The lights-on indication is displayed in the multi-information display of the instrument cluster.
a30zzn00000437


Operation

Lights-on indicator light
1.  When the light switch is in the TNS (parking lights) position, the instrument cluster sends (1) a TNS (parking lights) signal to the body control module (BCM) via CAN communication.
2.  The body control module (BCM) sends (2) a lights-on indicator light on signal to the instrument cluster.
3.  The instrument cluster turns the transistor on (3) based on the lights-on indicator light on signal.
4.  When the transistor turns on, a ground circuit with the lights-on indicator light is established and the lights-on indicator light turns on (4).
a30zzn00001909
Lights-on indication
1.  The instrument cluster receives (1) the lights-on indicator light on signal from the body control module (BCM) via CAN communication, it displays (2) the lights-on indication in the multi-information display.

Headlight High-beam Indicator Light


Purpose

•  The headlight high-beam indicator light notifies the driver that the headlights HI are turned on.


Function

•  When the instrument cluster receives the headlight HI on signal sent from the body control module (BCM) via CAN communication, it turns the headlight high-beam indicator light on.


Structure/Construction

•  The headlight high-beam indicator light is built into the instrument cluster.
a30zzn00000440


Operation
