Hello, I need a socket diagram for a 3-pin Fiat because one cable does not go to the computer and it is probably damaged - no communication with the ECU. Someone help?

So one pin is not connected in the cube anyway, connect as in the above picture and what are you trying to connect?

Check that there is ground on the middle pin.

Don't make it up, this is EDC 15c7 and there is no L

Sure, possibly multiecuscan I do this for the kilograms.

cdifem 3 expert and the autocom, no communication, more needs a diagram where which wire goes in the bundle. and can the immo affect the lack of communication ??? as far as I know it is removed.

removed immo should not affect communication, wires from the plug should go to the ECU

just that one white and yellow goes to the cabin and when I found the same in the plug, there is no passage but I'm not sure if it's the same. it is best if I have a diagram or know which pin in the cube is from the k line of the l line someone will help? and if this white and yellow goes to the cabin, can I connect it immediately with ecu ??

You need to look for the ecu pinology and check if there is a transition, what is the driver there? Added after 9 [minutes]: Maybe it will help you

I saw this diagram, but I do not see the 3-pin cube here Added after 1 [minutes]: and the lack of the clutch pedal sensor nothing to do with it ?? Added after 1 [hours] 30 [minutes]: bosch 0 281 010 486 needs a pin description for such a computer

It is not possible to connect to the controller, even if you have everything unplugged, all you need is mass, plus and the K line, there you have EDC 15c7?

I think it's d2841hc Added after 3 [minutes]: this is my computer Added after 1 [minutes]: I know that the k line goes to pin 7 I think I'm wrong ??? and where is the l line?

k line to which pins when dripping? and line l where with the drip? Added after 59 : nowhere does it write that it is edc 15c7 Added after 1 [minutes]: and if there is no l line, it will normally connect to the computer ?? Can I change the 3 pin socket to OB 2 and it will work ??

Not all have L lines, it will work on the K line itself, it does not write on the controller but this is what I say, yes you can as long as the power, ground and K line were in the right place in OBD

and the usual cdief 3 will embrace it ??
