Problems solving
• If there is 3 seconds lasting faulty tone after ignition switch ON or shifting into reverse gear, there occurred
disconnection or damage of some sensor.
Number of faulty sensor is displayed on the main control unit:
If there is faulty or disconnected more than one sensor, display shows numbers of all the faulty sensors
subsequently.
Number of faulty sensor is indicated also audibly by the number of beeps following the faulty tone.
Change faulty sensor as soon as possible, the whole device is out of order!
On the vehicle, separate sensors are numbered as following:
Sensor 1 front sensor with the shortest cable
Sensor 4 front sensor with the longest cable
• If irregular false obstacle indication occurs, it can be one of the following problems:
Frost on sensors Clean sensors
Sensors are placed too low Place sensors higher or tilt axe of sensors upwards
Rear side of sensors in a contact Create separation between sensor and vehicle body
with chassis of vehicle
• If it is necessary to disconnect some wire from the control unit cable box, use attached extraction tool (11).
• If it is necessary to connect some wire to the control unit cable box, use attached spare contact (12).
