Self-diagnosis for convenience system
Synchronising/re-matching of existing radio-operated remote control keys
Radio-operated remote control keys must be synchronised if the vehicle can no longer be unlocked or locked via remote control and the key data is already known to the vehicle (can be recognised by fault memory entry "00955 to 00958 - keys 1 to 4").
Method for synchronising radio-operated remote control keys for vehicles with data level up to "09xx" (see Note)
-
‒ Press a button on the radio-operated remote control key.
If the vehicle is neither locked nor unlocked:
-
‒ Lock and unlock the vehicle within 30 seconds the via driver's door lock.
-
‒ Then check the function of the re-matched radio-operated remote control key.
If the vehicle still cannot be locked or unlocked, the key must be re-matched/adapted.
New methods for synchronising radio-operated remote control keys for vehicles with data levels as of "10xx" (see Note; introduced from model year '03)
-
‒ If the vehicle is locked, unlock it with the key via the lock in the driver's door.
-
‒ Press the unlock button on the radio-operated remote control key (fault is stored).
-
‒ Insert the key in the ignition lock and switch on the ignition (valid immobiliser message).
-
‒ Switch off the ignition again and remove the ignition key.
-
‒ Press the unlocking or locking button on the radio-operated remote control key (command is executed).
If the vehicle still cannot be locked or unlocked, the key must be re-matched/adapted.
Notes:
-
◆ The data level of the convenience system central control unit can be established via the function "01 - Interrogate control unit version".
-
◆ Following replacement or disconnection of the battery during repair work requiring this, all the radio-operated remote control keys for the vehicle must be synchronised.
-
◆ When changing the battery of a radio-operated remote control key, only that particular key must be synchronised.
-
◆ If the synchronisation procedure is unsuccessful, matching of the radio-operated remote control key(s) to the convenience system central control unit must be performed.
