DSC control unit
For the first time, the tire pressure monitoring system functionality has now been integrated in the Dynamic Stability Control (DSC) system.
The remote control receiver receives the radio signals from the wheel electronics. The remote control receiver is connected via LIN bus to the Body Domain Controller (BDC). The Body Domain Controller (BDC) forwards the signals via the bus connection to the DSC control unit.
The DSC control unit processes the messages transmitted by the wheel electronics. Above a speed of 20 - 30 km/h, the following messages are sent by the electronics on each wheel:
- Tire pressure
- Tire air temperature
- Remaining service life of the battery
- Data from the acceleration sensor and Identification Feature (ID) of the wheel electronics
- Transmission mode (passive, standby, learning)
| Item | Explanation |
|---|---|
| 1 | DSC control unit |
| 2 | Hydraulic unit |
| 3 | 38-pin plug connection |
The DSC control unit transmits information to the instrument cluster and headunit.
The instrument cluster indicates tire pressure loss via a warning and indicator light and issues a Check Control message.
The central information display connected to the headunit can be used to call up further information on the tire pressure via the vehicle status.
The head unit must also be employed to initialize the tire pressure monitoring system.
