The CMTC module in the overhead console has three buttons used to select various functions. The CMTC selector buttons will not operate until
the ignition is in the RUN position.
When the ignition switch is first turned to the RUN position the CMTC display:
-
Blanks momentarily
-
All segments of the VFD will light for one second
-
Blanks momentarily
-
Returns to the last mode setting selected before the ignition was last switched OFF.
Thermometer
Engine temperature can increase the displayed temperature. The CMTC is designed to dampen temperature readings when the vehicle is moving at
a rate slower than 18 miles per hour.
The outside temperature is measured from a sensor mounted in the front of the vehicle. If the temperature is more than 55 °C (131 °F) or the
temperature sending line is shorted to ground, the temperature display should read SC. If the temperature is less than -40 °C (-40 °F), or the
sending line is an open circuit, the display should read OC.
The CMTC will not allow the temperature reading to increase when the vehicle is not moving.
