Good Evening. I bought from AliExpress this elm327. cannot be recognized by the multiecuscan program. i want to do proxy alignment .i put the yellow wire and then the obd. It says there is an error connecting. do i have to remove any resistance? I can't read the resistance because it's too small. thanks for any help.!Image

Hi! I'm new to the forum and sorry for my english. I have a bluetooth module (For italian cars) that works perfectly with the A..aOBD program on Android. This module does not communicate with Fiatecuscan and Multiecuscan programs via CAN network. I bought a USB module (according to the store, it is suitable for Fiat ECU reading), it doesn't communicate with any program either, only engine information and ABS, steering with a green cable. The "service" doesn't work either. I modified this module so that the R4 resistor was removed. No change. Please someone help me. The OS is Win10 Home 64bit, the car is Fiat Croma 1.9JTD 16v, 2005. MES 3.91r. Thank you. Andrew

ALFAEDDY Thank you for answering the same questions over and over again for so many years because no one wanted to read two pages of the thread. I enjoyed spending 5 hours reading the topic last night and was full of admiration for your patience. Respect.
