Special vehicles multifunction control module task - GF82.25-P-4102-02S

The special vehicle multifunction control module (SVMCM [MSS]) (N26/9)  is used to monitor and control special functions for special vehicles.

The control module is able to differentiate between two basic statuses : 

• Taxi
• Special-purpose vehicles:
  • Official and special protection vehicles
  • Police and emergency vehicles
  • At the request of the customer, a panic alarm for private vehicles is available.

Depending on control module encoding and installation, the SVMCM assumes the following tasks:

• Taxi roof sign system control
• Taxi emergency alarm system control
• Partial special signal system function control
• Panic alarm function control (private vehicles)
• Control and regulation of the heated wind shield (special protection vehicles)

Control module encoding 

Control module encoding is carried out with the Star diagnostic tool via the EIS control module (N73)  .

Exception:

The heated windshield and police vehicle disguised as a taxi functions are encoded directly in the SVMCM.
