DESCRIPTION
• The following ECO drive levels can be checked on the ECO indicator of upper meter:
- Instant ECO drive level
- Cumulative ECO drive level
• VCM sends the signals below to the combination meter via CAN communication:
- Instant ECO indicator signal
- ECO tree signal
• The combination meter sends the signals it received via CAN communication from VCM to the upper meter.
• Based on the signals received via the communication line, the upper meter indicates the ECO drive level on
the ECO indicator.

OUTSIDE AIR TEMPERATURE DISPLAY
OUTSIDE AIR TEMPERATURE DISPLAY : System Description
INFOID:0000000010122397
SYSTEM DIAGRAM
DESCRIPTION
• VCM transmits a ambient sensor signal to the combination meter via CAN communication.
• ABS actuator and electric unit (control unit) transmits a vehicle speed signal to the combination meter via
CAN communication.
• The combination meter calculates the outside air temperature based on the signals received from VCM and
ABS actuator and electric unit (control unit) via CAN communication.
• The combination meter sends the calculated outside air temperature signal to the upper meter via the com-
munications line.

• The upper meter indicates the outside air temperature according to the outside air temperature signal
received from the combination meter by means of communication line.
• For outside temp (Alert), refer to
MWI-35, "INFORMATION DISPLAY : System Description"
.
NOTE:
• The indicated temperature is corrected based on a power switch signal, ambient temperature detected by
the ambient sensor, and vehicle speed signal. The indicated temperature is not raised under vehicle speed
less than 20 km/h (12 MPH).
• The ambient sensor input value that is displayed on “Data Monitor” of CONSULT is the value before the cor-
rection. It may not match the indicated temperature on the outside air temperature display.
• Depending on motor heat or heat on the road surfaces, an ambient temperature may be indicated higher
than actual one.
