MWI-22 < SYSTEM DESCRIPTION > SYSTEM The combination meter measures and displays travel time (ignition switch ON time). Travel Distance The combination meter calculates mileage, based on the following signals and displays the mileage on the Ambient Temperature • The combination meter corrects an indicated temperature, based on various signals. lated value is displayed on the information display. Correction Process (Temperature indicated soon after the ignition switch ON) • A temperature indicated soon after the ignition switch is turned ON depends on the time from the ignition switch OFF to ON and a temperature detected by the ambient sensor. When any condition described below is met, an ambient sensor-detected temperature is indicated. - Time from the ignition switch OFF to ON ≥ Predetermined time - Sensor-detected temperature < Temperature at the last ignition switch OFF Correction Process (Temperature at the Ignition switch ON) • A temperature indicated when the ignition switch is ON depends on a vehicle speed, an ambient sensor- detected temperature, and traveling time. The temperature on the information display is corrected to an ambient sensor-detected temperature when the following condition - Ambient sensor-detected temperature < Temperature on the information display A temperature on the information display is not updated when the following condition is met. - Ambient sensor-detected temperature ≥ Temperature on the information display - Vehicle speed ≤ 20 km/h (12 MPH) A temperature on the information display slowly rises to an ambient sensor-detected temperature when the following condition is - Ambient sensor-detected temperature ≥ Temperature on the information display - Vehicle speed ≥ 20 km/h (12 MPH) A temperature on the information display rapidly rises to an ambient sensor-detected temperature when the following condition - Ambient sensor-detected temperature ≥ Temperature on the information display - Vehicle speed ≥ 20 km/h (12 MPH) - When driving more than set time A/C auto amp. connection recognition • The combination meter judges the A/C auto amp. connection/disconnection, based on an A/C auto amp. connection recognition signal to judge the presence/absence of the ambient sensor power output.
