Message Center Module Remote Compass Module
Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the remote compass module. 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 affected. Do not use magnetic tools when servicing the RCM.
The remote compass module (2) is a separate stand alone module mounted to the top of the instrument panel. The RCM can be accessed by removing the instrument panel center stack hood
If the remote compass module is inoperative and requires replacement. Refer to REMOTE COMPASS MODULE .
The remote compass module data is transferred on the controller area network data bus circuit. The RCM and electronic vehicle information center compass temperature display will not function properly if the bus messages are not properly received. If no EVIC/compass temperature display data is displayed, test the CAN data bus circuit communications, the RCM, the instrument cluster functions and the totally integrated power module. Any diagnosis of the RCM and EVIC/compass temperature display system should begin with the use of a scan tool and the appropriate diagnostic service information.
For complete circuit diagrams, refer to appropriate SYSTEM WIRING DIAGRAMS information.
