Circuit/System Description
The compass information is displayed in the driver information center (DIC). The DIC displays the compass direction received via the serial data circuit
from the compass heading. As the vehicle travels with or against the earths magnetic pull, the compass heading signal to the DIC changes. As a result of
the compass heading signal change, the DIC adjust s and changes the direction of the compass display. When an invalid signal is sent to the DIC or a
malfunction exists in the compass heading, the DIC blanks the display and displays '--' or 'CAL'.
Circuit/System Verification
1. Ignition ON, verify that the DIC compass does not display "C" or "CAL".
^
If the DIC compass displays "C" or "CAL", perform the Compass Calibration and Magnetic Variance procedure. Refer to [Compass
Calibration and Magnetic Variance (DIC)] [Compass Calibration and Magnetic Variance (ISRVM)].
2. Verify that the DIC compass display is not blank.
^
If the DIC compass display is blank, replace the IPC.
Repair Instructions
