FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[fiat340]

My ELM327 works great with engine but i can't connect to the CAN bus.
I have found de resistor R04 (121) (red marked) is this the right one, or maybe the resistor R14 (681).

Hello

If the chip C4 is the term MCP2551
Then the red-marked resistor R04, which is must be removed.

Hello Lutxana1964

Unfortunately, I can help you with your problem, because it is not always safe
whether a general diagnostic software also connects to each vehicle.

Especially French cars have so many problems

You've got to be the first to find out whether Torque also compatible with your N16 is

In other forums they said that the TORQUE is compatible con Nissan N16 and they are coneted with the ELM327, I think that the problem is my ELM327.
I have got 5 led´s and only is light on the red and is starting the led last green but the others no.

Hi

I liked the order to insert a picture

Have you installed an app for your ELM interface FTDI drivers?

Hello Lutxana1964

The problem of resistor is often described here is relevant only Multiecuscan, I have not heard of the other diagnostic software have problems with.
Otherwise, it is a different problem

Furthermore, this problem is not to find resistor to your ELM interface.

And the red LED will only show that the interface is receiving power.
the other LEDs flash only when transferring data

Sorry I can not help you.
