Diagnosis And Testing - Electronic Vehicle Information Center

The Electronic Vehicle Information Center (EVIC) data is obtained from several components on the Controller Area Network (CAN) Data Bus circuit. The EVIC will not function properly if the bus messages from any of these components is not received. If no EVIC data is displayed, check the CAN Data Bus circuit communications, the Instrument Panel Cluster (IPC) functions and the Body Control Module (BCM).

The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the EVIC and the CAN Data Bus circuit. Refer to the appropriate SYSTEM WIRING DIAGRAMS article for complete circuit schematic or connector pin-out information.
