Integrated Circuit Display
WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
The integrated circuit display is a vacuum fluorescent tube display that contains the odometer, trip odometer, outside air temperature, and compass display on base clusters and the message center display on message center clusters. For additional information on the message center, refer to INFORMATION AND MESSAGE CENTER . The compass module and outside air temperature sensor are hardwired to the instrument cluster. The odometer information is transmitted from the PCM through the CAN circuits to the instrument cluster. The instrument cluster displays the appropriate message(s) upon receipt of the outside air temperature, compass heading, and odometer data received.
