MODEL 221.0 /1, 216.3 as of model year 09 /YoM 08 with CODE (551) Anti-theft alarm system (ATA [EDW]) with CODE (763) Radio remote control with panic switch
General function requirements
- C. 15C OFF
Alarm triggered by panic switch, general
With the panic alarm it is possible to trigger the visual and acoustic antitheft alarm (ATA) with the transmitter key (A8/1) (e.g. in an emergency).
Function sequence when panic alarm and ATA alarm are triggered simultaneously:
The panic alarm has priority over the ATA alarm.
If both alarms are actuated the alarm with the higher priority is output and the ATA alarm is suppressed. This alarm is still actuated in the background. If one of the two alarms is terminated or is interrupted, the other is still actuated.
The alarm triggering with the panic switch comprises the following subfunctions:
- Function sequence for actuating panic alarm
- Function sequence for panic alarm output
- Interrupting function sequence for panic alarm
Function sequence for actuating panic alarm
When the panic alarm button on the transmitter key is actuated fort ≤ 2 s, it transmits a radio signal via the rear window antenna amplifier module (A2/12) to the rear SAM control unit with fuse and relay module (N10/2) and relays it to the EIS control unit (N73).
Parallel to the radio signal, an infrared signal is transmitted to the driver door infrared sensor (B58) (precise aiming required).
This signal is read in by the Left door control unit (N69/1) (model 216) or left front door control unit (N69/1) (model 221) and is transmitted to the EIS control unit.
In both cases, the EIS control unit checks the access authorization of the transmitter key.
If the access authorization is valid, the EIS control unit transmits the "Activate panic alarm" command to the rear SAM control unit.
It then transmits the requests for visual and acoustic alarm via interior CAN.
Additional function requirements for panic alarm output
- Panic alarm triggered
Function sequence for panic alarm output
The alarm is output by the exterior lights, interior illumination as well as the alarm siren (H3/1).
The acoustic alarm is output by the rear SAM control unit actuating the alarm siren via the rear SAM-LIN.
The interior illumination is switched on by the overhead control panel control unit (N70).
The following components of the exterior lights are actuated:
- by the front SAM control unit with fuse and relay module (N10/1):
- Left turn signal light (E1e5)
- Right turn signal light (E2e5)
- by the rear SAM control unit:
- Left turn signal light (E3e1)
- Right turn signal light (E4e1)
- by the left door control unit (model 216) or left front door control unit (model 221):
- Left outside mirror turn signal light (E6/5)
- by the right door control unit (N69/2) (model 216) or right front door control unit (N69/2) (model 221):
- Right outside mirror turn signal light (E6/6)
The duration of the visual and acoustic panic alarm is equal, however, stored separately in the alarm siren and rear SAM control unit.
Interrupting function sequence for panic alarm
The panic alarm is interrupted when the panic alarm button on the transmitter key is actuated briefly.
The function sequence for interrupting the panic alarm is the same as for actuating the panic alarm.
