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 List” of M.U.T.-III SE is the value before the correction. It may not match the indicated temperature on the information display.
Depending on engine heat or heat on the road surfaces, an ambient temperature may be indicated higher than actual one.
