CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the Remote Compass Module (RCM) located at the top center of the instrument panel. Do not place any electronic devices (cell phones, laptop computers, PDAs, portable DVD players, etc), on or near the instrument panel as the RCM performance may be effected. Do not use magnetic tools when servicing the RCM.
The Compass Mini Trip Computer (CMTC) data is obtained from several components on the Controller Area Network (CAN) and Local Interface Network (LIN) Data Bus circuits. The CMTC will not function properly if the bus messages from any of these components is not received. If no CMTC 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). Should the RCM 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 CMTC, the RCM, the CAN Data Bus and Local Interface Network (LIN) Data Bus circuits. Refer to the appropriate wiring information for complete circuit schematic or connector pin-out information.
