Driver Information Center (DIC) Description and Operation: Compass

The driver information center (DIC) displays the compass based on serial data message from the BCM. The compass module communicates with the body control module (BCM) through a bi-directional data circuit. The instrument panel cluster (IPC) receives compass information from the BCM via the serial data circuit. The compass is displayed in the DIC with other vehicle information and is displayed at the bottom line of the DIC. The compass display is "- -" (dashes) when a malfunction is present with the compass module or a compass serial data communication fault exists. The compass displays 'CAL' or 'C' when the compass needs to be calibrated. Cycle the ignition before performing the compass magnetic variation zone adjustment procedure. The trip/reset switch is used to change the compass zone or calibrate the compass.

Check that the compass module is properly installed in the vehicle since this may cause the compass to malfunction. The embossed arrow on the top of the compass module should be parallel to the centerline of the vehicle.

Your compass may be located in the inside rear view mirror (ISRVM). If your compass is located in the ISRVM, refer to Compass Calibration and Magnetic Variance (Driver Information Center (DIC)) , Compass Calibration and Magnetic Variance (Mirror) , Compass Malfunction (DIC)  or Compass Malfunction (Mirror)  or to Automatic Day-Night Mirror Description and Operation .
