AMBIENT TEMPERATURE DISPLAY
id092200021500
Purpose
• The ambient temperature display notifies the driver of the ambient temperature.
Function
• The instrument cluster displays the ambient temperature based on the ambient temperature signal sent from the PCM via CAN communication.
• The ambient temperature is displayed within -40—70 °C {-40—158 °F}. -40 °C {-40 °F} is displayed if the ambient temperature is -40 °C {-40 °F} or less, 70 °C {158 °F} is displayed if 70 °C {158 °F} or more.
Road ice warning function
-
• When the instrument cluster receives an ambient temperature signal of 4 °C {39 °F} or less from the PCM, it displays the ice mark. After receiving the ambient temperature signal of 4 °C {39 °F} or more, it flashes the ice mark and the ambient temperature display for about 10 s to warn the user that the road surface may be icy.
• Once the instrument cluster performs the road ice warning, it will not perform it again until it receives an ambient temperature of 6 °C {43 °F} or more.
• The ice mark and ambient temperature flashing pattern is as indicated in the figure.
Construction
• The ambient temperature is displayed on the LCD in the instrument cluster.
Operation
1. When the ignition is switched ON (engine off or on), the instrument cluster receives (1) an ambient temperature signal from the PCM.
2. The instrument cluster displays (2) the ambient temperature in the LCD based on the ambient temperature signal.
Fail-safe
• Not applicable
