METER ILLUMINATION CONTROL : System Description

INFOID:0000000009721253

SYSTEM DESCRIPTION

The combination meter controls the meter illumination by the illumination control switch signal from the meter
control switch and the position light request signal transmitted by the BCM via CAN communication.

Daytime Mode

Meter illumination level can be adjusted in 22 steps using the illumi-
nation control switch (1) in daytime mode.

Nighttime Mode

• Combination meter changes the meter illumination to the nighttime mode by the position light request signal

from BCM via CAN communication.

• Meter illumination can be adjusted in 22 steps using the illumination control switch in nighttime mode.

Driver Welcome Function

Ring illumination gradually turns ON when a driver gets in the vehicle with intelligent key and closes the driver
side door.
NOTE:
Ring illumination gradually turns OFF when not turning the ignition switch ON at a certain period of time.

Description

Combination meter

Turns the oil pressure warning lamp ON/OFF according to the oil pressure switch signal received 
from BCM via CAN communication. 

IPDM E/R

Reads the ON/OFF signals from the oil pressure switch and transmits the oil pressure switch signal 
to the combination meter via BCM and CAN communication. 

Oil pressure switch

Refer to 

MWI-52, "Description"

. 

BCM

Transmits the oil pressure switch signal received from IPDM E/R via CAN communication to the 
combination meter via CAN communication.

Dial Effects Function

Combination meter detects the engine start when input engine speed signal at first. Pointers of speed meter
and tachometer sweep and ring illumination gradually turns ON when combination meter detects the engine
start. Then, combination meter starts the normal control.
NOTE:
• Engine coolant temperature gauge and fuel gauge do not function.
• Dial Effects Function can be turned ON/OFF from “SETTING” on the information display.

• The combination meter receives the information required for controlling the operations of the information dis-

play from the BCM via CAN communication.

• The combination meter incorporates a trip computer that displays the warning / information according to the

information received from various units.

PARKING BRAKE RELEASE WARNING

The combination meter indicates the parking brake release warning judged by the vehicle speed signal
received from the ABS actuator and electric unit (control unit) via CAN communication and the parking brake
switch signal from the parking brake switch.

Warning Operation Condition

Parking brake release warning is judged if all of the following conditions are fulfilled.
• Vehicle speed is 7 km/h (4.3 MPH) or higher
• Parking brake switch ON
