Driver/Vehicle Information Display: Testing and Inspection

DIAGNOSIS AND TESTING - EVIC

The Electronic Vehicle Information Center (EVIC) relies upon electronic message inputs received over the Controller Area Network (CAN) data bus from other electronic modules in the vehicle. The EVIC will not function properly if the bus messages from any of these modules are not received. If no EVIC data is displayed, check the CAN data bus communications as well as other instrument cluster (also known as the Cab Compartment Node/CCN) functions.

The use of a diagnostic scan tool and the proper diagnostic procedures is required for further testing of the EVIC and the CAN data bus. Refer to the appropriate wiring information for complete circuit schematics and connector pin-out information.
