Manual Compass Calibration

MANUAL COMPASS CALIBRATION

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the Remote Compass Module (RCM) located under the instrument panel center stack hood. 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.

NOTE: Confirmation that the proper variance zone is programmed, is recommended whenever manual compass calibration is performed, for the appropriate procedure Adjustments.

The electronic compass unit features a self-calibrating design, which simplifies the calibration procedure. This feature automatically updates the compass calibration while the vehicle is being driven. This allows the compass unit to compensate for small changes in the residual magnetism that the vehicle may acquire during normal use. If the compass readings appear to be erratic or the Electronic Vehicle Information Center (EVIC) displays "CAL", perform the following manual calibration procedure. Also, any time EVIC service replacement components are installed, they must be calibrated using this procedure. Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

NOTE: Do not attempt to calibrate the compass near large metal objects such as other vehicles, large buildings, or bridges; or, near overhead or underground power lines.

Calibrate the compass manually as follows:





1. Start the engine but leave the vehicle in "PARK".
2. Press and release the SCROLL push buttons (5 or 6) until "System Set-up" is displayed and highlighted.
3. Press the STEP push button (3) to open the menu.
4. Using the scroll buttons, scroll through until " Calibrate Compass " is displayed and highlighted.
5. Momentarily depress and release the STEP push button to initiate the calibration procedure. The "CAL" symbol will come on solid in the EVIC display next to the compass direction that is displayed.
6. Slowly drive the vehicle on a level surface, away from large metal objects and power lines, through one or two complete circles not exceeding 8 km/h (5 mph). The "CAL" message will disappear from the display to indicate successful compass calibration.
7. Confirm that the correct direction is now indicated by the compass.
8. Using the scroll button, select " Turn Off Menu " to exit.

NOTE: If the compass display indicates an inaccurate compass heading or the display is locked up, the RCM (if equipped) may be inoperative and require replacement.

NOTE: If the "CAL" message remains in the display, either there is excessive magnetism near the compass, or the EVIC is inoperative. Attempt the calibration procedure at least one more time before performing EVIC diagnosis.

NOTE: If the wrong direction is still indicated in the compass display, the area selected for calibration may be too close to a strong magnetic field. Repeat the manual calibration procedure in another location.
