Bit serial data interface bmw
Diagnosis: The connected components have their own diagnosis functionality and monitor the following: The DME monitors the communication across the bit-serial data interface to the connected components. This means that wire faults are also detected. The executed functions are monitored for faults e. The DME then enters the fault in the fault memory. BSD interface to the alternator The alternator with BSD interface can actively communicate with the engine control module. The alternator is not linked to the charge indicator lamp, only to the engine control module. The alternator can detect a variety of faults.
The executed functions are monitored for faults e.Bit-serial data interface (BSD) The bit-serial data interface is a single-wire data bus with a data transfer rate of kBit/s. The following components are connected across the bit-serial data interface with the DME/DDE control unit. PicoScope software. Automotive diagnostics software, with free updates for life. • Regular updates to our PicoScope & PicoDiagnostics software include new features and . 1/23/ · BMW Battery Replacement – BSD Wire Disconnected, Negative Battery Cable. January 23, Share. This answer is applicable for many BMWs in addition to the one listed below. Q car year: car model: i I had my battery (Interstate) replaced at Firestone and I noticed the Bit Serial Data Interface wire was not connected.
The DME then enters the fault in the fault memory. BSD interface to the alternator The alternator with BSD interface can actively communicate with the engine control module.
The alternator is not linked to the charge indicator lamp, only to the engine control module. The alternator can detect a variety of faults.

The basic function of interfzce alternator is bmw ensured daga the communication between the alternator and Bit engine control is interrupted. Possible data The following possible faults aerial be distinguished from fault entries: High temperature control: The alternator interface overloaded; to be safe, the alternator voltage is reduced until serial alternator has cooled down again.
The charge indicator interfaec does not light up. The following cannot be detected: Coil interruption or short-circuit. Battery charge indicator lamp The signal for the charge indicator lamp to light up is transferred across CAN to the instrument cluster. The charge indicator lamp lights up if there is mechanical and electrical fault see above. Detection The above-mentioned calculation of the alternator moment and the rate of utilization of the alternator are heavily dependent on the type performance and manufacturer.
This is why the alternator provides the engine control with this data. The engine control adapts its calculation and set values to the exact type. Aim The precise calculation of the alternator moment and control of the load response function enables good idling of the engine.
Much more than documents.
iBt Control of the alternator voltage based on nominal values from the engine control enables a good charge balance esrial the battery. In the event of faults, only fault 2F12 is stored.
This means that in the event of a fault the entire signal path must be checked. Here, it makes sense also to use the diagnosis in the integrated automatic heating and air conditioning system. The engine management system MSS70 depends on a valid and plausible speed signal for a large number of its own functions.

The signal is transferred across the CAN bus. However, the speed signal is picked up by sensors of the control module for dynamic stability control. In the event of a fault, the test routines and test modules for that control module must be r. So my oil level was inactive for pretty long still struggling with it.
Oil Level INACTIVE! water pump runs longer than usual. 2E7C Bit serial data HELPPP
So bmw is 2E7C : Niterface interface data Bit, signal. And when I turn off the onterface serial pump runs longer than usual. And me and my mechanic got the diagram so Alternator water pump and data level run through BSD line. All the lines wires look ok. Except the purple wire that goes to from DME to Alternator is showing 0. Appreciate 0. Did you check the grounds points on the valve cover?
How about the IBS sensor?

Were their any other faults stored? Any misfire faults stored recently? And no i didnt check the IBS sensor, is it also connected with oil level sensor. This is why i wish our cars had dipsticks.P2E7C : Bit serial data interface, signal! Oil level INACTIVE! help
