Function requirements, general 

IMPORTANT The electronic ignition lock control unit sends the circuit status circuit 15R via the interior CAN to the front SAM control unit.

Garage door opener, general 

The garage door opener transmitter unit is a remote control capable of learning with which various receivers of the opening and locking systems for doors or gates can be activated.

The garage door opener is integrated into the inside rearview mirror.

The signals from the garage door opener are read in by the front SAM control unit via the wiper/inside rearview mirror LIN.

The garage door opener radio signal has a range of approx. 85 % of the original hand transmitter.

The following frequencies are available:

with code (231) Garage door opener:

In addition with code (232) Garage door opener with frequency 284-390 MHz:

On vehicles up to 31.5.11, user guidance (two-hand operation) consists of a single-color indicator lamp in the garage door opener (red).

On vehicles as of 1.6.11 user guidance (single-hand operation) consists of a multi-colored indicator lamp in the garage door opener (green, yellow and red).

The garage door opener function comprises the following partial functions:

Function sequence, transmit radio signal 

When one of the following buttons is pressed, a radio signal assigned to this memory is transmitted:

The indicator lamp in the garage door opener serves for function feedback (red up to 31.5.11, green as of 1.6.11).

Function sequence, program the memories 

Vehicles up to 31.5.11:

Keep desired garage door opener button pressed for at least t = 20 s. As a result the garage door opener changes into learning mode which is displayed by the flashing of the garage door opener (red) at a frequency of f = 1 Hz. Continue to press selected garage door opener button and hold original hand transmitter close to the garage opener transmitter unit with transmitter function activated for up to t = 90 s (s = 3 to 20 cm). The transmission frequency is now learnt.

In the process the garage door opener transmitter unit searches for the suitable frequency among the possible transmission frequencies. If the teach-in procedure is completely successfully, this is indicated by the garage door opener indicator lamp flashing quickly in red at a frequency of f = 5.6 Hz.

Vehicles as of 1.6.11:

Keep desired garage door opener button pressed for at least t = 10 s. As a result the garage door opener changes into learning mode which is displayed by the flashing of the garage door opener (yellow) at a frequency of f = 1 Hz. Then press original hand transmitter close to the garage opener transmitter unit with transmitter function activated for up to t = 90 s (s = 3 to 20 cm). The transmission frequency is now learnt. In the process the garage door opener transmitter unit searches for the suitable frequency among the possible transmission frequencies.

Successful termination of the teach-in procedure is indicated by the garage door opener indicator lamp illuminating green (fixed code learned in) or flashing green (variable code with f = 5.6 Hz learned in). An unsuccessful attempt is indicated by the garage door opener indicator lamp illuminating red.

IMPORTANT The garage door opener is approx. 85% compatible with the garage door opening systems offered on the primary turnover markets. If the original hand transmitter is not compatible with the garage door opener, a universal receiver ("Fix Kit Receiver") which reacts to the in-plant programming of the garage door opener can be installed in the garage.

Function sequence, erase the memories 

Vehicles up to 31.5.11:

To erase the memories, press the two outer garage door opener buttons (buttons 1 and 3) simultaneously for a period of a least t = 20 s. The garage door opener indicator lamp flashes in red for a period of t = 10 s. Release garage door opener buttons during flashing phase. The existing data of the memory locations is erased.

Vehicles as of 1.6.11:

To erase the memories, press the two outer garage door opener buttons (buttons 1 and 3) simultaneously for a period of a least t = 10 s. The garage door opener indicator lamp flashes green for a period of t = 10 s. Release garage door opener buttons during flashing phase. The existing data of the memory locations is erased.

IMPORTANT The garage door opener goes to the learn-in mode when one of the three garage door opener buttons is pressed again. If no programming is performed in learning mode during a period of t = 100 s, the garage door opener switches off automatically to protect the on-board electrical system.

Function sequence for resetting to as-delivered state 

To reset press the two outer garage door opener buttons (buttons 1 and 3) simultaneously for at least t = 30 s.

Basic setting:

Function sequence for protection against misuse 

With each communication the front SAM control unit transmits a security code to the garage door opener via wiper/inside rearview mirror LIN. If the safety code transmitted does not coincide with the stored safety code, the channels learned in are erased.

However, the national coding is maintained.
