FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[ATUDIO MAN]

thanks Eddy for the advice ..i thought i could bay a new pic18f2480 or ELM327 to reduce the coast ..the problem is any thing on the web .. i pay almost double of its price becoase of the shipping and costoms ,taxes fees ..thats it

So I repeat operation:
a) remove R4
b) ..........
c) connect pin 1 to pin 7 as shown in figure?

??

thanks

I have the same device.
you have verified that it works with these changes?
thanks

why did you get a new device?

Hi dotty ,
did you check my picture and firmware ?? what the value for this resistor ?
Pin1 in my circuit have a VCC bias its have Vcc across one drop resistor 47K is it OK to connect it to pin7

Hello,

As I said earlier, I bought a new 327 elm v 1.5 but I can not understand that I do change. Attached photos of the circuit .... Thanks in advance!

Hello

You have to remove the red circled resistor R04.
Then your ELM also works in the CAN protocol (ISO 15765)

Hi Im having a ELM327-USB V3.0 v1.4 Interface, I can connect to CAN Setup/ Proxy Alignment, CAN Info, Boot, Drivers Door, but I can't connect to Service Interval Reset on my Alfa 147 2.0 TS '01.

Do I have to destroy any Resistor?

Thank you in advance

I have this ELM 327 USB firmavare revision 1.3a or something I need to modify? if anything, this version is ok

I have this ELM too, and i can connect to Stilo 1.9 JTD (2002) and set service, but i can't connect it to Mito 1.6 JTDm with adaptor cable, FES doen´t detect anything.

Thanks!

Hi guys

I think I have the problem described here, unfortunately I am not very good at electronics but a resistor or two to unsolder would be no problem I recently bought this:



If anyone should have a clue I would be greatly greatly appreciated. Thank you!

I removed the R04 resistor and it now works like a charm

Can you connect into the CAN controlers?
As I see in your pics your tool it is 1.5
The chinese made this version 1.5 which can be version 1.3, 1.4 or in the bad case 1.2
Version 1.2 it is not support by the FES
So in this case you have to go in other CAN car and try to connect using a softwear for ELM327
And if you can connect in a car based on CAn, VW Golf 5, Skoda Octavia II, Ople Insignia, Opel Vectra C/Signium or Astra H etc in this case you have bad luck the tool is version 1.2
Good luck

....
And if you can connect in a car based on CAn, VW Golf 5...

Actually the Golf Mk 5 isn't a great one to test on. Tools using VAG's protocols (VCDS etc) connect on CAN via the car's CAN gateway.
Anything connecting on the EOBD protocols would pick up the engine controller on KWP2000 though, not CAN.
