Special vehicle multifunction control unit (SVMCU [MSS]), component description - GF54.21-P-4010LE
MODEL 221.1 with CODE (Z07) Top protection as of Model Year 09/Modification year 08 Fire extinguishing system, panic alarm system (GAS), emergency fresh air system
Location
The MSS control unit is located behind the right-hand trim in the luggage compartment in the right rear wheel well recess.
Task
The MSS control unit makes possible the connection of special mounting parts to the standard on-board electronics via the interior CAN.
In addition it has the following tasks:
- Reading in of sensors, pickups and signals
- Evaluation of input factors
- Actuation of components
Reading in of sensors, pickups and signals
The following components are read in via a direct line:
- Inside microphone (B25/3) (with panic alarm system)
- Emergency fresh air system control unit (N142) (with emergency fresh air system)
- GAS control unit and special signal system (N26/12) (with panic alarm system)
- Fire extinguishing system control unit (N100) (with fire extinguishing system)
- Activate button for emergency alarm system, left knee guard (S62/16) (with fire extinguishing system)
- Activate button for emergency alarm system, right knee guard (S62/17) (with fire extinguishing system)
- Activate button for emergency alarm system, rear fresh air vent (S62/18) (with fire extinguishing system)
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor and the affected components are then actuated.
Actuation of components
The component are actuated via the interior CAN.
The signals are transmitted by the special vehicle multifunction control unit via the interior CAN. The resultant functions are described in the respective function descriptions (see block diagram or function schematic).
