System Description
WARNING: This page is about a different car, the 2008 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
- METER GAUGE AND WARNING/INDICATOR
Meter/Gauge:
METER/GAUGE REFERENCEItem Details Speedometer Based on signal received from wheel speed sensor, skid control ECU calculates vehicle speed and transmits data to combination meter (CAN) Tachometer*1 Combination meter receives engine rpm signal from ECM, and gauge needle operates (CAN) ODO/TRIP meter - Combination meter receives vehicle speed pulse integration signal from skid control ECU, and ODO/TRIP meter display operates (CAN)
- Using ODO/TRIP switch, ODO/TRIP meter display changes
Fuel receiver gauge Combination meter receives fuel amount information measured by fuel sender gauge, and gauge needle operates (Direct line) Engine coolant temperature gauge*2 Combination meter receives water temperature signal from ECM, and gauge needle operates (CAN) A/T oil pressure receiver gauge Combination meter receives A/T oil temperature signal from ECM, and gauge needle operates (CAN) Oil pressure receiver gauge*3 Combination meter receives engine rpm signal from ECM (CAN), and receives oil pressure sender signal from oil pressure sender (Direct line). Then meter measures signals and gauge needle operates. Voltmeter*4 Monitors IG voltage and gauge needle operates (Direct line) HINT:
*1: w/ Tachometer
*2: w/ Engine coolant temperature gauge
*3: w/ Oil pressure receiver gauge
*4: w/ VoltmeterWarning/Indicator:

MULTI-INFORMATION REFERENCE CHARTDisplay Outline Average Fuel Economy - Value that has been calculated by combination meter, which is based on distance driven and fuel consumption volume (fuel injection signal from No. 1 cylinder)
- This display is updated every 10 seconds
Current Fuel Economy - Value that has been calculated by combination meter. When ignition switch is turned ON, combination meter calculates this value based on distance driven and fuel consumption volume (fuel injection signal from No. 1 injector).
- This display is updated every 0.5 seconds
Distance To Empty - Value that has been calculated by combination meter. When ignition switch is turned ON, combination meter calculates this value based on fuel consumption data that combination meter continuously monitors and stores in its memory, and residual fuel volume data.
- This display is updated every km (mile)
Trip Timer - Calculates and displays elapsed time since engine start signal was input into combination meter
- This display is updated every second
Average Speed - Value that has been calculated by combination meter. This calculation is based on elapsed time since engine start signal was received by combination meter and vehicle speed signal received by combination meter.
- This display is updated every 10 seconds
- Warning display:
When a warning is necessary, the warning display interrupts the multi-information display.
- The master warning light may illuminate or blink and buzzer may sound depending on the item in the multi-information display.MULTI-INFORMATION REFERENCE CHART

- The master warning light may illuminate or blink and buzzer may sound depending on the item in the multi-information display.
- Cruise information display:
- ACCESSORY METER
- This system has the following functions.
- Clock:
When the ignition switch is turned ON or ACC, the clock display is ON.
- Cruise Information:
For cruise information, four type of information (Outside temperature, average fuel economy, instant fuel economy, and distance to empty) can be displayed.
The cruise information units can be changed by using the SETUP switch.
Outside temperature → Average fuel economy → Instant fuel economy → Distance to empty.
METER REFERENCEInformation Outline Displays outside temperature in accordance with the outside temperature sensor signal from the A/C amplifier (manual A/C) or A/C ECU (auto A/C). - Displays a value that has been calculated by the combination meter, which is based on the distance driven and the fuel consumption volume (fuel injection signal from the No. 1 cylinder).
- This display is updated every 0.5 seconds.
- Displays a value that has been calculated by the combination meter. When the ignition switch is turned ON, the combination meter calculates this value based on the distance driven and the fuel consumption volume (fuel injection signal from the No. 1 injector).
- This display is updated every 0.5 seconds.
- When the ignition switch is ON, displays a value that has been calculated by the combination meter (meter ECU), which is based on the following: 1) fuel consumption data that the combination meter (meter ECU) continuously monitors and stores in its memory; and 2) residual fuel volume data.
- This display is updated every 1 mile (1.6 km).
- Security Indicator Light:
- informs the driver of the theft deterrent system status.
- Depending on operation of the transponder key ECU, the interior security indicator light comes on or starts blinking.
- Clearance Warning Indicator:
- Displays the location of the obstacle and the approximate distance between the vehicle and the obstacle.
- Turns on and off according to the intuitive parking assist system status.
- Emits an intermittent sound to inform the driver that the ECU has detected an obstacle within the prescribed ranges.
- Clock:
- This system has the following functions.
