Manual Calibration Mode

Manual Calibration Mode:

Manual calibration is normally needed only if the electronic compass module is new and has never been calibrated for the vehicle. The manual calibration should be performed if the direction bars are turned OFF and CALIBRATE is shown on the display. When CALIBRATE is displayed, the electronic compass module has detected a strong magnetic field and cannot show the proper heading.

Use the following procedure to perform manual calibration:
1. Rear defogger off.
2. Press the MODE button until CALIBRATE is displayed. (The variation mode is stepped through before reaching the manual calibration mode, about three seconds).
3. Release the MODE button, the direction bars start to rotate.
4. Drive the vehicle in small circles and do not drive faster than 10 miles per hour.
5. Drive in small circles until the CALIBRATE display turns OFF, about one to five circles.

The compass is now calibrated. This is confirmed when the CALIBRATE display turns off and the direction bars show the true vehicle heading.

If the MODE button is not released after the CALIBRATE display turns on, the display returns to heading mode in a few seconds. Also, the calibration mode can be aborted if the mode button is pressed or if the ignition switch is turned to OFF during the calibration procedure.

If the rear defogger is on, CALIBRATE flashes and the chime sounds indicating that the electronic compass module can not enter the manual calibration mode. After five seconds, CALIBRATE stops flashing and the compass display returns to the heading mode.

If the manual calibration mode is entered and the vehicle is not moved within a few minutes, the CALIBRATE display flashes and the chime sounds indicating that the electronic compass module is returning to the heading mode and the old calibration values are retained.

If the CALIBRATE display flashes and the chime sounds after the vehicle is driven in circles while in the manual calibration mode, refer to the System Check. System Check
