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.

Check that the sonar sensors are properly aligned (no deformation in sensor mounting areas).
Check that snow, mud or other foreign objects are not on the sonar sensors.
Check that there is no deformation, scratches or other damage to the sonar sensors.
Check that water has not accumulated in the sonar sensors.

CAUTION: Use water, cotton swab, or other soft material for cleaning the sensors.

Inspect for the following:
- Physical damage to wiring
- Physical damage to harness connectors
- Loose or disconnected harness connectors
- Physical damage to system components

Check that there are no obstacles within each sonar sensor's detection range.

Sonar sensors	Detection range
Front	Approx. 1.0 m (3 ft.) maximum
