Preliminary Check

INFOID:0000000009480098

DESCRIPTION

The purpose of the sonar sensor preliminary check is to confirm that there are no outside factors affecting the

sonar system.

CONDITIONS

• Ignition switch ON

• No obstructions within 3.0 m (10 ft.) of sonar sensors

SONAR SENSOR STATUS CHECK

• Check that the sonar sensors are properly aligned (no deformation in sensor mounting areas).

• Check that snow, mud or other foreign objects are not adhering to 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.

1. Inspect for the following:

-

Physical damage to wiring

-

Physical damage to harness connectors

-

Loose or disconnected harness connectors

-

Physical damage to system components

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

3. Check that there are no nearby ultrasound sources such as the sounds of vehicle horns, motorcycle

engines or truck air brakes. 

4. Check that the vehicle is on a level surface.
