FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[Alfaeddy]

Hello Elio65

Unfortunately, the images often of poor quality, you unfortunately also

Your photo flash makes everything very dazzle

But when I look at the board, I can see I should have found the resistor.
And I marked the red

Should remove this resistor and also work with your ELM Multiecuscan

Hi,

I bought un'elm327, and when I go to read, with Fiat ECU scan, the data of ABS and airbags, I find the error that can not be read on the K-line to pins 5 and 7 ....... it seems to me;

how can I change it, I'll post pictures:

Hi Giuseppe

Which car / model / year you want to read?

And why here all have such bad pictures representing
can not see anything?

The images must have a higher resolution of at least 800 kb <

In these pictures, I can not see anything

Hi Jerrywang

Your pictures are too big and have nothing to do with your interface!
Why did you set here?
800 x 600 pixels is sufficient


It is clearly not an interface


Which car / model / year you want to read??

If you still have soldered a capacitor (560 pF) and a resistor (100 ohms) to pin 6 + 14?
This is completely unnecessary, remove it again

Hello Giuseppe

Please this time slowly

This ELM interface you can convert without something
on Fiat Stilo read the ECU / ABS / Steering

For the air bag you need a KKL interface

For the Fiat Croma
So you can read without a rebuild your ECU / ABS / xenon

Only for the airbag / Body Comp etc. you may need to change something on the interface.

If you get no connection to the ECU you have the settings / Com port set incorrectly
First check the time settings
