System Wiring Diagram

Operation

• The buzzer in the instrument cluster sounds when 

all the following three conditions are met: 

— The ignition switch is in the LOCK or ACC 

position.

— The key is in the steering lock (key reminder 

switch is on).

BURNT OUT BULB CHECK FUNCTION OUTLINE

E5U092255430N15

• The microcomputer in the instrument cluster illuminates the brake system warning light when the ignition switch 

is in the ON position. Due to this, the brake system warning light function can be inspected for a burnt out bulb.

System Wiring Diagram

Operation

• The microcomputer in the instrument cluster 

illuminates the brake system warning light for 
approx. 3 s and then turns it off when the ignition 
switch is turned to the ON position. (When the 
parking brake switch or the brake fluid level 
sensor is on, the brake system warning light 
remains illuminated.)

SPEEDOMETER CONTROL CONSTRUCTION/OPERATION

E5U092255430N18

System Wiring Diagram

Operation

• The vehicle speed signal sent from the PCM via 

the CAN system is input to the microcomputer in 
the instrument cluster. The microcomputer 
calculates the current vehicle speed based on the 
vehicle speed signal, and sends an output signal 
to the speedometer.

the instrument cluster. The microcomputer 
calculates the current engine speed based on the 
engine speed signal, and sends an output signal

FUEL GAUGE CONTROL OUTLINE

E5U092255430N21

• The fuel level signal is output from the fuel gauge sender unit to the microcomputer in the instrument cluster. 

Fuel gauge variation caused by fluctuating fuel level when cornering or driving on a slope, is reduced by 
microcomputer control.

End Of Sie

FUEL GAUGE CONTROL CONSTRUCTION/OPERATION

E5U092255430N22

System Wiring Diagram

Operation

• A resistance according to fuel level is sent from 

the fuel gauge sender unit to the microcomputer. 
The microcomputer calculates the average 
resistance within a specified time, and sends the 
output signal to the fuel gauge based on the 
calculated value.

WATER TEMPERATURE GAUGE CONTROL CONSTRUCTION/OPERATION

E5U092255430N24

System Wiring Diagram

Operation

• The engine coolant temperature signal sent from 

the PCM via the CAN system is input to the 
microcomputer in the instrument cluster. The 
microcomputer calculates the current engine 
coolant temperature based on the engine coolant 
temperature signal, and sends an output signal to 
the water temperature gauge.

OIL PRESSURE GAUGE CONTROL CONSTRUCTION/OPERATION

E5U092255430N26

System Wiring Diagram

Operation

• The engine coolant temperature signal and 

engine speed signal sent from the PCM via the 
CAN system is input to the microcomputer in the 
instrument cluster. The microcomputer calculates 
the oil pressure based on the engine coolant 
temperature signal and engine speed signal, and 
sends the output signal to the oil pressure gauge 
according to the calculated value.
