Model 213 up to model year 2021 with code 965 (Taxi/rental car - electrical pre-installation)
Location
The multifunction control unit is located under the left cover in the trunk.
Task
The multifunction control unit is responsible for the following tasks:
- Reading in of signals
- Evaluation of input factors
- Actuation of components (accessory devices)
Reading in of signals
The input factors are read in over the following connections:
- Direct line
- Interior CAN (CAN B)
- Multifunction CAN (CAN K)
Direct line
The signals from the following components are read via a direct line:
- Taximeter (A50) (with CODE 336 (Taximeter console in OCP [DBE]))
- Emergency alarm system "Delete" button (S62/5) (with code 934 (Taxi emergency alarm system))
- Emergency alarm system "Trigger" button (S62/6) (with code 934 (Taxi emergency alarm system))

Interior CAN
The signals are read in by the multifunction control unit over the interior CAN.
Multifunction CAN
The signals are read in by the multifunction control unit over the multifunction CAN.
Evaluation of input factors
The input factors that have been read in are evaluated by the integrated microprocessor whereupon the relevant components (accessory devices) are then actuated.
Actuation of components (accessory devices)
The actuation of the components takes place via the following connections:
- Direct line
- Interior CAN
- Multifunction CAN
Direct line
The following components are actuated via a direct line:
- Taximeter (with CODE 336 (Taximeter mounting console in OCP))
- Two-way radio (A49) (accessories) or radio data transceiver (A49/5) (accessories)
- Roof sign lamp (E14/4) (with CODE 342 (Roof sign connection for taxi))
Interior CAN
The signals are sent by the multifunction control unit over the interior CAN.
Multifunction CAN
The signals are sent by the multifunction control unit over the multifunction CAN.
