- Circuit 15R ON
The electronic ignition lock control unit (N73) transmits the circuit status of circuit 15R via the interior CAN (CAN B) to the overhead control panel control unit (N70).
Garage door opener, general
The garage door opener (A67n2) is a remote control capable of learning with which various receivers for the opening and locking systems for doors or gates can be activated. The garage door opener is integrated into the inside rearview mirror (A67). The garage door opener is connected to the overhead control panel control unit via the roof LIN (LIN B13). The garage door opener radio signal has a range of approx. 85 % of the original hand transmitter.
On vehicles with code 231 (Garage door opener) the following frequencies are available:
- 27 MHz
- 30 MHz
- 40 MHz
- 418 MHz
- 433 MHz
- 868 MHz
On vehicles with code 232 (Garage door opener) frequencies between 284 and 390 MHz are available.
A67e4User guidance (single-hand operation) is provided by multi-colored indicator light on the garage door opener (green, yellow and red).
The garage door opener function comprises the following partial functions:
- Programming memories
- Transmitting the radio signal
- Erasing memory locations
- Resetting as-delivered state
- Transmitting the security code (protection against misuse)
Programming memories
Hold down garage door opener button 1 (A67s1), garage door opener button 2 (A67s2) or garage door opener button 3 (A67s3) for the time of minimum 10 s. The garage door opener changes into learning mode which is displayed by the flashing garage door opener (yellow) at a frequency of 1 Hz. Then hold original hand transmitter with activated transmitter function for at least up to 90 s in the vicinity of the garage door opener (3 to 20 cm). The transmission frequency of the original hand transmitter is now programmed. The garage door opener selects the right frequency from 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 5.6 Hz learned in). An unsuccessful attempt is indicated by the garage door opener indicator lamp illuminating red.
The garage door opener is approx. 85 % compatible with the garage door opening systems offered on the primary sales 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.
Transmitting the radio signal
When one of the following buttons is pressed, a radio signal assigned to this memory is transmitted:
- Garage door opener button 1
- Garage door opener button 2
- Garage door opener button 3
The function is confirmed by the garage door opener indicator lamp (green).
Erasing memory locations
To clear the memory, press the two outer garage door opener (buttons 1 and 3) simultaneously for at least 10 s. The garage door opener indicator lamp flashes green for 10 s. Release garage door opener buttons during flashing phase. The existing data of the memory locations is erased.
The garage door opener goes to the learn-in mode when one of the three garage door opener buttons is pressed again. If programming is not performed during the learning mode for a period of 100 s the garage door opener switches off automatically to protect the on-board electrical system.
Resetting as-delivered state
To reset press the two garage door opener outer buttons (buttons 1 and 3) simultaneously for at least 30 s.
Basic setting:
- "Chamberlain" algorithm (310 MHz) (with code 232 (Garage door opener))
- "Keelog" algorithm (433 MHz) (with code 231 (Garage door opener))
Transmitting the security code (protection against misuse)
Each time function is actuated, the overhead control panel control unit transmits a safety code to the garage door opener via roof 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.
