Anti-Theft Code

Gemeral Information

The "RNS 315" has anti-theft coding, which operates in conjunction with the instrument cluster.

After disconnecting the power supply, the radio navigation system is ready to be used again once the power supply is connected. The anti-theft code does not need to be entered again. The anti-theft coding must be activated for the first time and the radio navigation system must be connected in the same vehicle.

Reactivating a locked radio/navigation system is only possible by entering correct radio code number for anti-theft protection.

Use the Vehicle Diagnostic Tester to get the anti-theft code. The radio card and the label on the radio that were used in the past are no longer used.

Note

The Vehicle Diagnostic Tester must be connected "online" (network connection) to determine the anti-theft code. The user must have proper authorization to access the anti-theft code.

Anti-Theft Code, Deactivating

Special tools and workshop equipment required

• Vehicle Diagnostic Tester
• Vehicle Diagnosis System - Updated Cable - 3m -VAS5051/5a- or Vehicle Diagnosis System - Diagnostic Cable - VAS5051/6a- or Vehicle Diagnostic Tester - Diagnostic Cable - 5m -VAS5052/3-

Retrieving the Anti-Theft System Code Using the VAS Tester:

Select "Guided Functions""Guided Fault Finding" in the Vehicle Diagnostic Tester.

After all control modules have been checked:

• Press the "GO TO" button.
• Select "Functions/Component selection".
• Select "Body".
• Select "Electrical Equipment".
• Select "01-OBD-capable system".
• Select "radio or radio navigation system".
• Select "Functions"
• Select and start "radio code inquiry".

Authorization will be requested from the system: Then the operating data, the VIN and the radio serial number of the radio/navigation system will be automatically read out.

Note

When installing a new radio or one that has not been adapted to the vehicle yet, the tester may not be able to read the radio device number. In this case, enter the device number manually. The serial number can be found on a sticker on the unit and is also stamped into the side of the unit.

Then the anti-theft code will be displayed in the tester.

The radio navigation system anti-theft code must not be entered manually.

Deactivating the Anti-Theft Coding

• Turn on the radio/navigation.
• Enter the anti-theft code appearing in the display in the "RNS 315" number block and confirm it.

Unit is enabled and ready for operation.

Note

If the wrong radio code number was entered when overriding the electronic lock, first "SAFE" blinks in the display and "1000" appears again. The entire process may be repeated one more time. The number of tries is shown in the display. The unit will lock for approximately one hour if an incorrect code is entered again. That mean, it cannot be used. This lock is indicated by the word "SAFE" appearing continuously in the display. After one hour has elapsed in which the unit and the ignition must be switched on, the number of attempts disappears and the electronic lock can be deactivated again as described above. The cycle "two attempts, locked for one hour" still applies.
