P2E7C : Bit serial data interface, signal! Oil level INACTIVE! helpAm i safe to just disconnect it, clean it up, and put it back again without disconnecting the battery? I also still cant reset the oil service reminder warning when starting the car. I put everything back together and its still the same.
Bit-serial data interface (BSD)
Would i be right in thinking everything else on seria, BSD is working ok? I get water temperature, voltage etc all shown in ISTA so would that be safe to assume? I know you said passenger side motor mount, but my car is right hand drive so i just wanted to check.
How did you find that was the problem on yours, just a guess? I finally got it sorted this weekend.

After a long time diagnosing this it turned out to be the DME at fault. A quarter of the BMW dealer cost! Originally Posted by AWDxi. Appreciate 1. C post Repeat test.
Could anyone pls tell me what is meant by QLT?
Reputation: 0. Regards Hello QLTQuality, Level, Temperature, sensor and this is function exactly in the Oil levelling sensor look the part number 8 in realoem Realoem part number 8. Can you tell us what did you find to be the root cause? I have been chasing this fault code with no fix. Any help would be appreciated.
CCC module repair instruction step-by-step Author: mb intercace. Replies: 1. 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.

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. PicoScope software. Automotive diagnostics software, with free updates for life. • Regular updates to our PicoScope & PicoDiagnostics software include new features and . P16C6 - 2E7C - bit-serial data interface (BSD), signal. Going through the diagnosis procedure, I got a term referred to as 'QLT'. The repair procedure is as thus.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 the alternator is also ensured if the communication between the alternator and the engine control is interrupted.
Possible faults The following possible faults can be distinguished from fault entries: High temperature control: The alternator is overloaded; to be safe, the alternator voltage is reduced until the alternator has cooled down again. The charge indicator lamp 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.
Updated NVH Kits
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.

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.

Hello mates,
I am working on a BMW X6 2008 model 6 cylinder petrol engine, I got this error code on the DME -
P16C6 - 2E7C - bit-serial data interface (BSD), signal.
Going through the diagnosis procedure, I got a term referred to as 'QLT'.
The repair procedure is as thus:
1. Disconnect all BSD_components (alternator, battery sensor, water pump) except for the oil sensor. Clear fault memory. Ignition off/on. If fault code is stored again: QLT is defective and must be replaced. Repeat test.
Could anyone pls tell me what is meant by QLT?
Regards
