Normal Operating Condition: Description: Compass

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

The electronic compass is highly protected from changes in most magnetic fields. However, some large changes in magnetic fields can affect it. Some examples are (but not limited to): high tension power lines, large steel buildings, subways, steel bridges, automatic car washes, large piles of scrap metal, etc. While this does not happen very often, it is possible.
During normal operation, the Compass Mirror will continuously update the compass calibration to adjust for gradual changes in the vehicle's magnetic "remnant" field. If the vehicle is subjected to high magnetic influences, the compass may appear to indicate false headings, become locked, or appear that it is unable to be calibrated. If this occurs, perform the calibration procedure.
If at any time the compass continually displays the incorrect direction or the reading is erratic or locked, verify the correct zone variance.

Symptom Chart

Symptom	Cause	Solution / Reference
The compass display reads "C".	Compass is not calibrated. Incorrect zone variance setting. Large change in magnetic field (Steel bridges, subways, concentrations of metal, car washes, etc.) Compass was calibrated incorrectly or in the presence of a strong magnetic field.	Perform Calibration. Refer to System Description .
Compass shows the wrong direction.
Compass does not change direction appears "Locked".
Compass does not show all the directions, one or more is missing.
The compass was calibrated but it "loses" calibration.
On long trips the compass shows the wrong direction.		Perform Zone Variation Setting if correct reading is desired in that location. Refer to System Description .
