Troubleshooting
The "RNS 315+" is equipped with OBD.
Use Vehicle diagnostic tester in "Guided Fault Finding".
Electronic Anti-Theft Protection
The Radio Navigation System (RNS) is equipped with an electronic anti-theft system which operates in conjunction with the instrument cluster. The radio code is stored internally inside the RNS and inside the instrument cluster.
After disconnecting the power supply to the RNS, it is ready for use and the radio code does not need to be entered again. The requirement is that the first activation of the electronic anti-theft system follows and that the RNS is reconnected in the same vehicle.
Use the Vehicle diagnostic tester to get the radio code. The radio card and the label on the RNS that were used in the past are no longer used.
• The Vehicle diagnostic tester must be "online" (connected to the network) in order to get the radio code and the user must be authorized to access radio codes.
Electronic Anti-Theft Protection, Deactivating
Reactivating a locked RNS is only possible by entering correct radio code number for anti-theft protection.
Determine the radio code using the Vehicle diagnostic tester:
- Connect the Vehicle diagnostic tester.
- Select Guided Fault Finding.
- Use the GO TO button to select the "function/component selection" and the following menu options one after the other:
• Body
• Electrical Equipment
• 01 - On Board Diagnostic (OBD) capable systems
• Radio/navigation system
• Radio/navigation system functions
• Radio code inquiry
An authorization to the system will be requested: Then the operating data, the VIN and the radio serial number of the radio/navigation system will be automatically read out.
• It is possible that the Vehicle diagnostic tester will not be able to read the serial number when a new RNS is installed. In this case, enter the serial number manually. The serial number can be found on a sticker on the unit and is also stamped into the side of the RNS.
The Vehicle diagnostic tester will display the anti-theft code.
Manually enter the radio code in the RNS.
Electronic Anti-Theft System, Deactivating
- Turn on the RNS.
"SAFE" appears in the display for approximately 10 seconds, after that "1000" appears.
- Enter the correct radio code using the buttons on the radio.
- Press the input screen to confirm in the entry.
The RNS is enabled and ready for operation.
Use the correction screen to erase an incorrect code.
It is possible to enter the radio code again if it was entered incorrectly. If radio code is entered incorrectly twice, then the RNS is locked for an hour. Leave the RNS and ignition on. The process can be repeated again after an hour. Note: Always two attempts, after that the RNS will lock up for one hour.
