Elevation System Check

Elevation System Check

1. Check the parking aid system to make sure that the system does not see signals caused by ground reflections.





2. The following system check should be carried out with the vehicle on a 3.0 m wide by 4.5 m deep (10 ft wide by 15 ft deep) smooth concrete surface, free of all obstacles and noise from fans and pneumatic tools.

3. Turn the ignition switch to the ON position, engine off.

4. Set the parking brake on.

5. Place the transmission in REVERSE (R).

6. Verify that no audible alerts are heard. If audible alerts are heard, check to make sure the bumper is correctly installed and is not tilted downward so that the sensor is pointing toward the ground.
- If the audible warning tone is heard, refer to Parking Aid Special Tool(s) Used With Diagnostics in the Diagnosis and Testing.
