Compass Calibration

WARNING: This page is about a different car, the 2003 Chrysler Concorde, 2003 Chrysler 300M, 2002 Chrysler Concorde, and 2002 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: Do not place any external magnets, such as magnetic roof mount antennas, in the vicinity of the compass. Do not use magnetic tools when servicing the overhead console.

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 out of calibration, perform the following calibration procedure. Also, new service replacement EVIC modules must have their compass 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: Whenever an EVIC module is replaced, the variance number must also be reset.

Calibrate the compass manually as follows:

Turn the ignition switch to the ON position. If the C/T data is not currently being displayed, momentarily depress and release the C/T push button to reach the C/T display.
Depress the Reset push button and hold the button down until "CAL" appears in the display. This takes about 10 seconds, and appears about 5 seconds after "VARIANCE = XX" is displayed.
Release the Reset push button.
Drive the vehicle on a level surface, away from large metal objects and power lines, through one complete circle at between 3-5 MPH (5-8 KM/H) in not less than 20 seconds. The "CAL" message will disappear from the display to indicate that the compass is now calibrated.
