Terminating resistors in the CAN
Terminating resistors are fitted to each end of the wiring to prevent reflection on the wiring. These terminating resistors are integrated into each control
unit. The interconnection prevents the resistors from being measured with the ohmmeter from the outside.
Tuner
Tuner
The tuner is part of the PCM2 (on the main board).
Unlock counter
Interruptions occur in the system if perfect communication is no longer possible. If the relevant threshold values are exceeded, an entry is recorded in the
appropriate control unit and the 'unlock counter' is incremented.
Voice Control System (VOCS)
Voice Control System (VOCS)
The VOCS is designed as a module box which can be pushed into the PCM2 (optional). After the insertion, an electronic switch is opened and the
module is integrated into the MOST ring.

NOTE: The activated drive link is automatically switched off after approximately 20 seconds.
Wake-Up Function
Wake-Up Function
In an idle state, all control units that are connected to the PCM2 are in sleep mode. When the PCM2 is switched on, 'the light' which is reinforced by the
connected MOST control units and forwarded is switched on via the gateway.
