18 Troubleshooting
18.1.4 Control does not work
To localize and remove the fault, proceed step by step as described below.
18.1.5.1 External inuences
• Reective surfaces (mirrors, reective stripes...) in the vicinity may interfere with the remote control distance detection.
• Under certain circumstances, special light sources (uorescent lamps, light beacons...) may interfere with infrared communication.
• The control may be adversely aected by strong electromagnetic radiation (e.g. near high-current equipment).
If the faults occur only in certain locations or situations, check the area for the above interference and try to avoid it.
18.1.5.2 Machine cabling
• Are fuses F11 and F12 OK?
• Are the connectors on the N1 control unit dirty or wet?
• Is the N1 control unit properly fastened?
• Are both infrared sensors P1 and P2 clean and undamaged?
• Is the cabling from N1 to P1 and P2 undamaged? Do not forget that there is the X5 interconnecting connector near the sensor at
the front of the engine compartment.
• Are the N3 manual control cable and the corresponding connectors undamaged and clean? Do not forget the X1 connector on the
inside of the bonnet.
