elm327 can not working, what resistor should i remove?

[nickromano]

i have this interface and i've changed those capacitors with 2 560pF but still won't work.
anyone can tell me what is the resistor between CAN L and CAN H that i need to remove from the pcb??



thanks!

Hello

Why did you solder these capacitors?
And at what point?

In my opinion, your board is a resolder unnecessary
It is with this strain ELM interface, mostly by setting error

can isn't working. maybe there is an unecessary resistor between can L and can H but i don't know what it is

Hello

These capacitors are not installed properly!

Just look at this thread again to
viewtopic.php?f=5&t=1493


Here is the layout of ELM Electronics' should be displayed where these capacitors and resistors.

But I have yet had no ELM327 these components soldered into the
are needed.

The resistance needs to be removed. MCP2551 is in front of the chip (6 +7)
soldered.
If this does not exist.
Must be removed no resistance.

Otherwise, the connectivity problem is due to drivers or settings of the COM ports
