Electronic Vehicle Information Center - Description

DESCRIPTION





The Electronic Vehicle Information Center (EVIC) system provides the vehicle operator with a convenient access to a wealth of useful information. This includes information that assists the operator in properly operating and maintaining the vehicle, cautions and warnings that improve the safety of the vehicle and its occupants, and information concerning environmental variables outside of the vehicle. The EVIC also provides an interface from which the vehicle operator can view and select from several programmable electronic feature options to customize those features to his or her particular preferences.

The EVIC system includes the following major components, which are described in further detail elsewhere in this service information:

- Ambient Temperature Sensor - An ambient temperature sensor is located on the front bumper support beam behind the radiator grille opening of the front fascia and ahead of the cooling module.
- EVIC Display - A reconfigurable, multicolor, Thin Film Transistor (TFT) display (8) unit is located between the speedometer (11) and the tachometer (1) and is integral to the Instrument Cluster (IC). Instrument Cluster - Description.
- EVIC Switches - An EVIC switch pod containing six momentary switch push buttons is located in the left horizontal spoke of the steering wheel.
- Remote Compass Module - A Remote Compass Module (RCM) is concealed behind the Integrated Center Stack (ICS) display unit within the instrument panel.

These EVIC components communicate with each other and with other systems and components throughout the vehicle using a combination of hard wired and resistor Multiplexed (MUX) switch and sensor inputs, the Local Interface Network (LIN) data bus and the Controller Area Network (CAN) data bus. Communication - Description.

Hard wired circuitry connects the EVIC system components to the electrical system of the vehicle. These hard wired circuits are integral to several wire harnesses, which are routed throughout the vehicle and retained by many different methods. These circuits may be connected to each other, to the vehicle electrical system and to the EVIC system components through the use of a combination of soldered splices, splice block connectors, and many different types of wire harness terminal connectors and insulators. Refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and connector repair procedures, further details on wire harness routing and retention, as well as pin-out and location views for the various wire harness connectors, splices and grounds.
