ELECTRONIC VEHICLE INFORMATION CENTER
The Electronic Vehicle Information Center (EVIC) is located in the overhead console. The EVIC supplements the standard vehicle
instrumentation. The EVIC uses a Vacuum Fluorescent (VF) display to supply the vehicle operator with a compass reading, outdoor temperature,
average fuel economy, distance to empty, instantaneous fuel economy, trip odometer, elapsed ignition on time, distance to service, warning
messages, service messages and memory system messages. It also provides an interface to enable and disable vehicle programmable features. If
equipped, the EVIC is also available with an integrated Universal Garage Door Opener (UGDO) known as HomeLink. Also if equipped, the EVIC
is available with a Tire Pressure Monitoring (TPM) System.
The EVIC function buttons are labeled C/T, RESET, STEP and MENU. The three UGDO buttons are labeled with dots to indicate the channel
number.
The BCM supplies most of the information displayed by the EVIC. Display information is received over the PCI bus. The EVIC sends and
receives data over the PCI bus, communicating with the BCM, PCM, and the Instrument Cluster. Tire Pressure Monitoring System information is
received by the EVIC in the form of radio transmissions. The tire pressure sensors are mounted to the vehicle wheels. For complete information,
refer to the Tire Pressure Monitoring System section.
