Electronic Vehicle Information Center Description

The Electronic Vehicle Information Center (EVIC) is located in the overhead console. The EVIC features a large Vacuum Fluorescent Display (VFD) screen for displaying information, and back-lit push button switches labeled C/T (compass/thermometer), RESET, STEP, and MENU. The EVIC module contains a central processing unit and interfaces with other electronic modules in the vehicle over the Programmable Communications Interface (PCI) data bus circuit.

The EVIC "Menu" push button provides the vehicle operator with a user interface, which allows the selection of several optional customer programmable electronic features to suit individual preferences.

If the vehicle is equipped with the optional universal transmitter transceiver, the EVIC will also display messages and an icon indicating when the universal transmitter transceiver is being trained, which of the three transmitter buttons is transmitting, and when the transceiver is cleared.

Data input for all EVIC functions, including VFD dimming level, is received through the PCI data bus circuit. The EVIC module uses its internal programming and all of its data inputs to calculate and display the requested data. If the data displayed is incorrect, perform the SELF - DIAGNOSTIC TEST. If these tests prove inconclusive, the use of a DRBIII(R) scan tool and the proper diagnostic procedures information are recommended for further testing of the EVIC module and the PCI data bus circuit.

The EVIC module cannot be repaired, and is available for service only as a unit. This unit includes the plastic module and display lens. If any of these components is faulty or damaged, the complete EVIC module must be replaced.

The Electronic Vehicle Information Center (EVIC) uses both non-switched and ignition switched sources of battery current so that some of its features remain operational at any time, while others may only operate with the ignition switch in the On position. When the ignition switch is turned to the On position, the EVIC module Vacuum Fluorescent Display (VFD) will return to the last function being displayed before the ignition was turned to the Off position.

The compass/thermometer display is the normal EVIC display. With the ignition switch in the On position, momentarily depressing and releasing the C/T (compass/thermometer) push button switch will cause the EVIC to return to the compass/thermometer/trip computer display mode from any other mode. While in the compass/thermometer/trip computer display mode, momentarily depressing and releasing the Step push button will step through the available trip computer display options.

The EVIC trip computer features several functions that can be reset. The functions that can be reset are:
- Average fuel economy
- Trip odometer
- Elapsed time

With the ignition switch in the On position and with one of the functions of the trip computer that can be reset currently displayed, depressing the Reset push button twice within four seconds will perform a global reset, and all of the trip computer information that can be reset will be reset to zero. With the ignition switch in the On position and the function that is to be reset currently displayed, momentarily depressing and holding the Reset push button for one second will perform a local reset, and only the value of the displayed function will be reset to zero. A global or local reset will only occur if the function currently displayed is a function that can be reset. The distance to service function can also be reset using the local reset method, but it will reset back to the Service Interval distance that is set in the EVIC programmable features mode.
