ELECTRONIC VEHICLE INFORMATION CENTER
CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass located in the overhead
console. 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 received. If no
EVIC data is displayed or the display indicates dashes "- -", check the CAN Data Bus circuit communications, the Instrument Cluster functions, the
Remote Compass Module (RCM) and the Totally Integrated Power Module (TIPM).
The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the EVIC, the RCM, the CAN Data Bus
and Local Interface Network (LIN) Data Bus circuits.
For complete circuit diagrams, refer to the appropriate wiring information. The wiring information includes wiring diagrams, proper wire and
connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness
connectors, splices and grounds.
