Outside Air Temperature Display

SYSTEM

OUTSIDE AIR TEMPERATURE DISPLAY : System Description


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 communications 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 "INFORMATION DISPLAY : System Description" Information Display.
NOTE:
- The indicated temperature is corrected based on an ignition 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 correction. 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
