METER SYSTEM
The distance to empty indication provides the driver with an estimation of the distance that can be driven
before refueling. The distance to empty is calculated using signals from the fuel level sensor unit (fuel remain-
ing), ECM (fuel consumption) and vehicle speed signals from the ABS actuator and electric unit (control unit).
JOURNY TIME
The travel time since last reset is displayed.
AVERAGE FUEL CONSUMTION
Average fuel consumption indication is calculated using vehicle speed signals from the ABS actuator and elec-
tric unit (control unit) and fuel consumption information from the ECM.
AVERAGE SPEED
The average speed mode can be selected to display the average speed since last reset. The indications are
calculated using vehicle speed signals from the ABS actuator and electric unit (control unit).
OUTSIDE AIR TEMPERATURE
The combination meter indicates the outside air temperature calculated by the temperature signal received
from the ambient sensor.
The indicated temperature is not readily affected by engine heat. It changes only when one of the following
conditions is present.
 The temperature detected by the ambient sensor is lower than the indicated temperature
 The vehicle speed is greater than 20 km/h (13 MPH)
(This is to prevent the indicated temperature from being affected by engine heat during low-speed driving.)
 The ignition switch has been turned to the OFF position for more than 3.5 hours. (The engine is cold.)
When the ambient air temperature falls below 3°C (37°F), the display starts flashing. Approximately 20 sec-
onds later, only “°C” flashes.
NOTE:
On vehicles equipped with auto A/C, the ambient sensor signal is shared with the front air control. The combi-
nation meter is notified of the signal sharing via the auto A/C sense circuit.

DTC B2205 VEHICLE SPEED CIRCUIT
DescriptionINFOID:0000000001374685
The ABS actuator and electric unit (control unit) provides a vehicle speed signal to the combination meter via
CAN communication lines.
DTC LogicINFOID:0000000001374686
Diagnosis ProcedureINFOID:0000000001374687
Symptom: Displays “VEHICLE SPEED CIRC [B2205]” as a self-diagnosis result of combination meter.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select “METER/M&A” on CONSULT-III.
2. Using “SPEED METER” on “DATA MONITOR”, compare the value of DATA MONITOR with speedometer
pointer of combination meter. Speedometer and DATA MONITOR indications should be close.
Is the inspection result normal?
YES >> Perform ABS actuator and electric unit (control unit) self-diagnosis. Refer to BRC-25, "CONSULT-
III Function (ABS)" (with ABS) or BRC-105, "CONSULT-III Function (ABS)" (with ESP/TCS/ABS).
NO >> Replace combination meter. Refer to MWI-94, "
Removal and Installation".
DTC CONSULT-III display Detection condition
B2205VEHICLE SPEED CIRC
[B2205]Malfunction is detected when an erroneous speed signal is input for 2 seconds or more.
