With modern technology, the different tasks can run in parallel and simultaneously communicate on the same physical layer. As stated before, INPA gives you BOTH a detailed definition AND the corresponding P-code. The 4-digit code number itself is 'non-specific' in many instances, but there are 'additional digits' or identifiers which are NOT read or interpreted by 'Non-BMW' Scan Tools. I scanned the codes and it came back with 281D DME: BSD generator:signal and 281C DME:Bit-serial data interface (BSD): signal. 2E7C Bit-serial data interface, signal 2E98 Alternator. Going through the diagnosis procedure, I got a term referred to as QLT. Alternator 2E98 and Bit-serial data interface 2E7C codes. Car in question is 2003 325i with SULEV M56 Engine and 120k miles on it. I had no idea the BMW hex code was so non-specific. P16C6 - 2E7C - bit-serial data interface (BSD), signal. can be developed by experts in these fields and carried out by using other protocols. aliabbass85 said: Hey guys, my car is throwing weird codes '281C and 281D' which are persistent and show up instantly after I reset them using INPA.

Other tasks such as encryption, transmitter authentication, re-flashing, etc. The distributed embedded control system can be developed using standard CAN Controllers and transceivers in a traditional way with well proven tools. New Kvaser white paper discusses ways to maximise CAN’s efficiency in next generation vehiclesīy using a Virtual CAN Bus, we separate the control task from other tasks.
