Hello friends of the room glider, I have the following problem: A short time ago I discovered a forum here, that was called “Distronic from today on board”. All right I thought to myself, if this is so easy I (self car mechatronics technician) can do so too. So said, done! I ordered all the parts (sensor, steering pole switch, cover plate) and I built the cable set myself. When I had installed all the parts I put it into the following ECUs with my StarDiagnosis I had to drive to the workshop and have it encoded for the ESP. Now I get the error message “Distronic without function” in the instrument cluster, if I read out the vehicle with my laptop, there is an error message in the ESP and in the Distronic an exclamation mark behind it. If I look at the error in detail he writes to me in the ESP: “ESP ECU (N47/5) or ECU DTR (A89) new p In the event memory of the Distronic it says: “The CAN communication is disturbed”! Then I carried out a voltage test on the front of the plug by means of a multimeter. The power supply is (12V) and the CAN is clearly measurable (2,3V and 2,8V), moreover I can access the control unit. Despite all this, I have now re-enacted the CAN bus lines and got the same error message. “The CAN communication is disturbed” Now ask ic h here for advice and would be very grateful about your proposals for solutions.
