ELECTRONIC VEHICLE INFORMATION CENTER
(EVIC) OVERHEAD CONSOLE
The Electronic Vehicle Information Center is a
computer controlled warning system which, monitors
various sensors used on the vehicle. The system sup-
plements the warning indicators in 8the instrument
cluster. Visual warning messages are displayed by a
digital display in the overhead console (Fig. 1).
When a warning message has been activated, a
tone will sound to attract the driver's attention. The
warning message will then be displayed on the over-
head console until the condition is corrected or a new
display function is called up. A tone will announce each new warning condition.
For complete diagnostic procedures for the EVIC
systems, refer to the Body-Chassis Diagnostic Test
Procedures Manual. The EVIC has a 24 function system that provides

dition exists. These messages are displayed on the
overhead console. For complete EVIC overhead console operating in-
structions, refer to the Owners Manual provided with
the vehicle.
