Driver/Vehicle Information Display: Testing and Inspection

ELECTRONIC VEHICLE INFORMATION CENTER

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not place any electronic devices (cell phones, laptop computers, PDAs, portable DVD players, etc), on or near the instrument panel as the Remote Compass Module (RCM) performance may be effected. Do not use magnetic tools when servicing the RCM.

The Electronic Vehicle Information Center (EVIC) data is obtained from several components on the Controller Area Network (CAN) and Local Interface Network (LIN) Data Bus circuits. The EVIC will not function properly if the bus messages from any of these components is not receive. If no EVIC data is displayed or the display indicates dashes "- -", check the CAN and LIN Data Bus circuit communications, the Instrument Cluster functions, the Navigational (NAV) radio, the Remote Compass Module, (RCM) if equipped and, the Totally Integrated Power Module (TIPM). On vehicles equipped with an RCM, should it become disconnected the instrument cluster display will go blank.

The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the Instrument Cluster, the NAV radio, the RCM, the CAN Data Bus and the LIN Data Bus circuits. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
