FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[effe75]

Hi Whiley I have a similar ELM327 cable. Which is exactly the resistor to remove? (I see no photo attached in your latest post). Thank you!

Sorted buzzed the board and found the 120 ohm resistor connected to 6 and 14, see picture attached, all works now and managed to do dpf reset and connect fully to ecu. I bought this kit off of amazon and for anyone who has this problem and has the red board see picture below of 120 ohm resistor to remove.

Hi Whiley, I have the same circuit board but I'm unsure what to do. There doesn't seem to be a photo attached. Please could you give a bit more advice? Cheers.

For my ELM327 USB interface, the 120ohm resistor is located here:

Encircled in blue. Usually between pins 6 and 7 of the CAN transceiver integrated circuit (8 pin SOIC, here named 1044)
