Mazda CX-5 Service & Repair Manual: Ambient Temperature Display
Purpose
-
The ambient temperature display notifies the user of the ambient temperature.
Function
-
The instrument cluster displays the ambient temperature based on the ambient temperature signal sent from the PCM as a CAN signal.
-
The ambient temperature is displayed between -40—70°C {-40?160°F} If the ambient temperature is -40°C {-40°F} or less, -40°C {-40°F} is displayed, and 70°C {160°F} is displayed if the temperature is 70°C {160°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.
Ambient temperature display switching function
-
The ambient temperature display can be switched between Celsius and Fahrenheit display. Refer to the workshop manual for the ambient temperature display switching procedure.
Construction
-
The ambient temperature is displayed on the LCD in the instrument cluster.
Operation
