Problems solving
If there is 3 seconds lasting faulty tone after shifting into reverse gear, there occurred disconnection or
damage of some sensor.
Number of faulty sensor is displayed on the control device.
If there is faulty or disconnected more than one sensor, display shows
periodically “En“ where “n“ are numbers of faulty sensors.
Faulty sensor(s) position is (are) displayed by the icon of the car.
Change faulty sensor as soon as possible, the whole device is out of order!
Sensor 1
sensor with the shortest cable
Sensor 4
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
Use angle brackets (8) or (10) to 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 (15).
