Troubleshooting
The front sensors shut down too early
The front sensors shut down before the speed reaches 10 km/h. The LEDs
in the control unit and on the external button switch off.
➤ Set parameter 14 ("number of speed signal pulses") to function "59", "61",
"62" or "63" (see chapter "Programming the system" on page 37).
Device indicates obstacles incorrectly
False alarms may have the following causes:
 Dirt or frost on the sensors
➤ Clean the sensors.
 Rain
➤ Check whether the front sensors are deactivated at a speed exceeding
10 km/h.
➤ Check whether a compatible speed signal is available.
If there is no speed signal available, set parameter 1 ("Speed sig-
nal/Time-out front sensors") to function "14", "15" or "16" (see chapter
"Programming the system" on page 37).
 The sensors were incorrectly installed.
➤ Adjust the position or height of the sensors (fig. 2).
➤ Make sure that the appropriate sensor bracket was used
(0°/12°/20°/bracket for metal bumpers).
 The sensors are in contact with the chassis.
➤ Separate the sensors from the chassis.
No acoustic signal.
➤ Check whether the yellow LED in the control unit and the LED on the
external button light up.
When the LEDs are flashing, the system is in emergency mode.
Start the vehicle again.
