– if sensor D (right, as viewed in the direction of motor vehicle
motion) or its circuit is faulty, the system indicates a faulty sensor with
four short low-tone horns with a duration of 0.5 s and interval of 0.3 s;
– if the control unit is faulty, a low-tone horn is given with a
duration of 2 s.
– if several sensors or circuits are faulty, the system indicates
it by sequentially listing faulty sensor numbers.
After malfunction alarm, the system switches off.
3. Audible hindrance alarm.
When a motor vehicle approaches a hindrance, an intermittent
acoustic tone signal is given with tone frequency of 1–3 kHz.
The interval time between tone ‘sendings’ reduces as the dis-
tance to the hindrance reduces, up to continuous horn at a distance
of 60 + 5 cm and less.
WARNING! Unauthorized modifications to the DPS circuit
diagram and design are strictly prohibited.
When operating, keep the parking system sensors (PSS) clean,
do not subject them to mechanical impacts. PSS surface should
be cleaned of contaminations using a soft cloth moistened with
a mild soap solution. When removing contaminations from the
PSS surface avoid applying pressure to its central part in order
to prevent damages.
DPS may not give a horn for a hindrance from behind in the
following cases:
– hindrance is located at a distance of less than 0.1 m;
– hindrance is a sharp or thin object (ropes, chains), posts with
diameter of max. 10 cm;
– hindrance surface of absorbent material ultrasound (snow,
clothes or other porous materials);
– hindrance has smooth round shape or is smooth inclined
surface (heavy inclination);
– the system’s sensors are covered with snow, ice or dirt;
– the motor vehicle moves in reverse with speed of over 5 km/h;
– system’s elements or electric circuits are faulty.
