Hello

This concerns Multiecuschan
and also
Torque does not read any control
Your interface you did not need to open.

Hello XCATale

The Resistor R14 must not be removed!!
This is wrong

I have also repeatedly described the
the user is not just any will remove a resistor.

OK, the thread is very long, but your ELM will be sure already described
Or send an email with better image

Yes I know, now I'll have to redo R14. The problem was R04

hello Eddy,
I have a Fiat Linea 2009 petrol Indian model.
I got one OBD scanner BT as per the pic below. I am not sure if you have already covered this version already.
When I connect to PC, it automatically installs the BT driver. But Multiecuscan could not find any any device.
Could you please tell me if it is the same R4 removal error?
Please find the PCB pictures below.
Thanks & Best Regards

Hello Mishradk

With this interface to connect to engine ECU, ABS must (with green adapter)
be possible. !
At your Linea

Without modification!

Otherwise, the setting or the driver are incorrect.
If the COM port of the interface identified without error?
you can see in the control panel of the PC.




But you sure you want Airbag, Body, Dashboard, service, etc. Read
also your interface R2 must be removed.

Thank you Eddy for your kind reply.
Ok I will remove the R2.

Above you talked about "with green adapter".
I just have the OBD II device. Do you mean that I need to make one adapter to connect the OBD II device to car's OBD II 16 pin interface?

Hello MishraDK

The green Adapter you need to read only for the ABS

All other controllers can be read without green adapter.

Eddy, Greetings from South Africa!

You have been given great advise on this topic! Unfortunately I am still having issues connecting to any ECU on my 2005 Fiat Punto 1.3 MultiJet.

I am using the exact same interface as this one that has been discussed previously:

download/file.php?id=1013&sid=a28fae480 ... 4994a80f1f

I have removed the resistor as recommended, but still no luck. When I test my interface I get the following results:

VagCom/KKL

Testing latency with 200 bytes of data...
Min latency: 8
Max latency: 16


Testing timers...
(The acceptable tolerance for results is ~5 ms)

System supports high resolution timer.

Testing timer with 1000 ms...
..result: 1000 ms

Testing timer with 250 ms...
..result: 19 ms

Testing timer with 750 ms...
..result: 15 ms

Testing timer with 100 ms...
..result: 7 ms

Any advise will be highly appreciated.

Regards
Chris

Hello Chris

The interface in the picture is a Bluetooth ELM Interface
But your test refers to a KKL interface

You have the wrong interface in the MES / settings adjusted.
