Functional Test
After the installation is completed you should test the system
thoroughly. For this test you require a test sample (preferred
material is a cardboard box approx. 500 x 500 mm, if there
is no box available, you can use a similar object material with
Step Activity
1 Ignition on / Tail light on
2 Engage reverse gear
3
Place the test sample in perpendicular to a sensor
within a range of 3 m behind the vehicle
4 Remove the test sample from the vehicle until the
beeping and LED outline are extinguished.
5
Move the test sample slowly inwards towards the
trailer sensor
6 Repeat step 4 with the second sensor
7 Repeat step 5 with the second sensor
Testing of the silent mode (night silent switch off)
8
Place the test sample in the distance as in step 3.
9
Engage the reverse gear twice (within 2 seconds)
10 Let the system work for min. 10 seconds. After this,
disengage the reverse gear.
11 Engage reverse gear once only.
Principle of operation
The controlled automatic braking commences at 1 meter
distance from the dock. The system is equipped with distance
sensors and distance from the dock is fi rst detected when the
trailer is in reverse and less than 3 meters away from the dock.
Working range
No Beep / Flashes
3 Beeps per sec (3 Hz) / Flashes
5 Beeps per sec (8 Hz) / Flashes
8 Beeps per sec (8 Hz) / Flashes

a smooth surface). Please ensure that there are no obstacles
situated within the range of 4 m x 4 m behind the vehicle. The
test procedure must be carried out in the following steps:
Result
LED outline marker has to shine
LED outline marker is deactivated when the radar is at 3 m from
the obstacle.
LED outline marker: slow fl ashing frequency
Reverse alarm: slow beep
Completed phase 1 (see picture below) (area greater than 3 m)
Run through the complete range of phases as shown within
diagram below.
See step 3/4
See step 5
LED outline marker: slow fl ashing frequency
Reverse alarm: no signal
LED outline marker: slow fl ashing frequency
Reverse alarm: returns to slow beep frequency
The braking command is delivered from the ECO Tronic EBS
via an auxiliary port. The braking at 1 meter distance lasts for 2
seconds before the system releases the brakes giving control
back to the driver.
Please note during the function test
that the test sample will be moved
always perpendicular to the respective
sensor axis.
The maximum detectable distance is
3 m from the sensor and detection is
shown below in fi ve phases. Please
study the sketch below.
