Initial Inspection and Diagnostic Overview

REMOTE COMPASS MODULE

The Remote Compass Module (RCM) data is transferred on the Controller Area Network (CAN) Data Bus circuit. The RCM and Electronic Vehicle Information center (EVIC) will not function properly if the bus messages are not properly received. If no EVIC data is displayed, check the CAN Data Bus circuit communications, the RCM, the Instrument Cluster functions and the Front Control Module (FCM). Any diagnosis of the RCM and EVIC system should begin with, the use of a scan tool and the appropriate diagnostic service information.

The use of a scan tool and the proper diagnostic procedures information are recommended for further testing of the RCM, EVIC and the CAN Data Bus circuit.

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.
