Write down your current Hardware Key, License Key and Removal Key. IT IS VERY IMPORTANT TO HAVE ALL 3 KEYS. Then you can proceed and install multiecuscan on your new system and get the new Hardware Key from the Registration window. Enter those 4 keys and your current email address below and click on the Request License button below. The system will verify your data and you will receive an email with your new License Key shortly. Multiecuscan is a diagnostic software for Italian vehicles.

Hi, A lot of people are having problems with some chinese ELM interfaces that cannot connect to CAN network even if they support all ELM 1.3 commands properly. There was one user here who bought 5 of these cheap interfaces with no luck and finally bought an expensive one. I also have one of these 'faulty' units and decided to play with it and see what is wrong. Well, it seems that the problem is electrical and is not very hard to fix. The problem is actually in the CAN termination method used in these interfaces - they use one 120 Ohm resistor connected between CAN-L and CAN-H. Multi Scan EcuAccording to the ELM327 datasheet the proper termination is to use 100 Ohm resistor on each of the 2 lines connected to ground through a 560 pF capacitor (see the picture below). So i just got two 100 Ohm resistors and two capacitors of 560 pF and fixed my interface as shows below. And it WORKS flawlessly now. The procedure is very simple: 1. Get two resistors of 100 Ohm and 2 capacitors of 560 pF. It should work without this. See the NOTE below. Remove the single terminating 120 Ohm (or whatever) resistor from the interface 3. Solder the new termination circuit. ![]() I did it directly on the OBD connector as it was easier for me. I did it in a hurry just for the so don't blame for the soldering quality on the pictures. It should work without this. See the NOTE below. Go to your car and enjoy. NOTE: It is reported that most of the new interfaces now have this problem! It was also reported by many users that the problem can be solved by simply removing the 120 Ohm termination resistor (which is connected between the two CAN lines, it is R14 on my photos but might be marked with different number on other interfaces) from the interface.
