Eddy... Now?

Hi Elio65

Your pictures are not better

Why did you use a photo flash? No Flash please

Why do you take such great size (3250 x 2600)
800 x 600 is quite enough

A large size (pixels) is better

I need a picture of the board!
not off the table around it

Use a macro to take a picture
It is very fuzzy

Can you see anything on your images???

can not read the number of the Chip in an red frame ?

I think your Problem ist not the ELM

Control your Setting / Interfaces Setting / Com port /
and you can read your ECU

For ABS / Airbag / usw. you need an yellow Adapter

hello
I have a problem with the connection to the ECU with a Chinese clone bluetoth.
The connection bluetoth is ok and the interface is regularly recognized but when I try to connect to the ECU interface software warns you that the connection is impossible.
In addition, the test code AT brings a positive response or negative randomly
I attach screenshots (OBDII.docx) and photos of the device.

Thanks for the reply

Hello puntomjdt1234

Wich CAR / model / year want you read ????


I dont can read the number from the Chip in the yellow frame ??
And thr resistor in blue frame ???

You can remove the white plastik Connector from the Board ?

Hello puntomjtd1234

If this is your Punto??

Then you should be with your interface to connect to your ECU can produce without removing a resistor on the board.

The ABS should be read with green adapter without modifiktation

Send me other times images

Hello Alfaeddy
Yes,that it is my car.
The chip in the yellow frame is a MCP2551
The resistor in the blue frame is marked 473
Under the plastic connector there is the resistance R04 but I can not read the value.
To remove the white plastic connector I have to desolder it.
If you think it may help you understand I can do it.

Thanks again for your help

Hello

This ELM you can without modification and read your ECU with a green adapter also the ABS
If this is not possible there is a setting error

But for service reset, Body Composition, CAN setup etc., there may be problems
This resistor R04 he connects the two pins in the picture??

If this is so?! remove R04

So you can read CAN bus protocol
