Hello wonderfull people. I have problem and my problem is that i have no comms with BCM, LMC, HVAC modules. SDD can see and communicate with all other modules except the ones which are on K Line. As for K line instrument cluster module is gateway, OBD2 socket connected with instrument cluster via DS2 bus. I have connected oscilloscope to K line, Can bus high and low, Can bus medium, they are fine, waveform is good. But DS2 lines seems dead. Does anybody know voltage of DS2 line or maybe waveform? My main suspect is instrument cluster now
but maybe i can do some diagnosis before changing it as otherwise it works fine. Or which chip is IC is responsible for DS2?
