Reverse Sensor
Reverse sensor operation (ultrasonic wave distance-measurement)
Sound is a kind of wave. Sound frequency that can be heard by human beings range from 20 Hz to 20 KHz.
Those that exceed 20 KHz are called ultrasonic waves. Since an ultrasonic wave is also a kind of sound, its
velocity in the air also equals the sound velocity of 340 m/s. Part of the ultrasonic wave will rebound when it
encounters an obstacle. So the distance between the sound source and the obstacle can be calculated according
to the sonic speed and the time difference between the emission of sound and the receipt of sound.
Reverse sensor system composition
This system is composed of a reverse sensor head unit (ECU), four sensors (SENSOR) and an external buzzer.

Combination Meter
If something is wrong with the meter, check the relevant component and circuit according to the connector defi-
nition. If the failure still cannot be eliminated, check whether the instrument itself has malfunctioned in the fur-
ther steps. The following diagram shows the view of the meter connector and its numb\
er.
