Bit Serial Data Interface Bmw
The bit-serial data interface is a single-wire data bus with a data transfer rate of 1.2 kBit/s.
16-BIT MONOTONIC OVER TEMPERATURE. 16-Bit DIGITAL-TO-ANALOG CONVERTER With Serial Data Interface DESCRIPTION The DAC714 is a complete monolithic digital-to.
3 Bit Serial Data Interface (BSD). The measured values from the IBS are provided to the DME by way of the Binary Serial Data Interface (BSD). ARTICLE BEGINNING NEW GENERATION 6-CYLINDER N52.

Replaced at Firestone and I noticed the Bit Serial Data Interface wire was not connected.
The following components are connected across the bit-serial data interface with the DME/DDE control unit: Transys software cracks.

- Alternator (varies according to version)
- Intelligent battery sensor (depending on model series)
- Preheating control unit (for diesel engines before introduction of the engines N47 / N57)
- Electric coolant pump (depending on variant)
- Oil condition sensor (depending on variant)
Only DDE control unit: Each component connected across the BSD is connected to its own pin on the DDE control unit. However, these pins are interconnected in the control unit.
Function
The following data is interchanged between the DME/DDE and the connected components:- Functional requirements from the DME/DDE to the components
- Identification data of the components to the DME/DDE
- Operating values of the components and their functions to the DME/DDE
- Fault messages of the components to the DME/DDE
Diagnosis
The DME/DDE monitors the communication across the bit-serial data interface to the connected components. This means that line faults are also detected.
The connected components have their own diagnosis functionality and monitor the following:
Configure Serial Interface
- The executed functions are monitored for faults (e.g. faulty preheating circuit for the preheating control unit)
- Internal faults in the components
Serial Interface Adapter
If a component detects a fault, it reports the fault across the bit-serial data interface to the DME/DDE. The DME/DDE then enters the fault in the fault memory.
