FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[momorec]

Hi All, could you please help me with my OBD cable. How it needs to be modified in order to work properly. Thanks.

Matchigo,
The PIC chip is a guaranteed success.
The STM8S207 chip is in doubt.

[Matchigo]

All right!
Thanks for the information. Can you give me a link to the good ELM/OBD ?

Hi Guys,

I'm trying to get my elm327 v1.5a cable to get to work. First bought this cable:



Downloaded the latest multiecuscan which is version 3.5 (still the free version) and tried to acces my panda 169 100hp.

I downloaded the drivers for my usb, but I can't get connectec to my ecu.

I'm getting these errors:




I'm trying to connect so I can reset my service interval. So does anyone have some tips?

I did all the settings as instructed in the manual, but I don't know what else I can do. I see that a lot of people adjust their cables?? Is that really necessary in my case?

Thnx!

Hello,
I have a registered version of MultiEcuScan, an ELM327 interface and i've just bought a yellow cable.
My ELM327 is working fine with MultiEcuScan for all features that don't required an additionnal cable (Engine is working fine for example). I've done an oil change, and thus I want to reset the service interval. This is the reason why i bought a yellow cable

Unfortunately, my yellow cable doesn't work. I have the message : elm327->ecu Connection failed!
Do you think that it is not working because of my ELM327 interface? Even if my ELM327 works fine for Engine in MultiEcuScan? If I have the resistor problem with my interface (it's a cheap version), should my ELM327 work with the Engine part?
Or is it because of my yellow cable? How can I test my yellow cable?

Can you help me with what resistance I have to eliminate?
They are R6, R9 ... I do not see 121

Hello, tell me what needs to be removed to connect to Fiat Punto 2 1.2 v8 2000

If I understand this correctly?

Hi all!
I am trying to connect to my Suzuki SX4, 2.0 Diesel Engine from Fiat (FPT D20AA, same as on Fiat Sedici). I need the access to Bosch Motor module, so I can update the injectors code.
I have tried with the following connector with little success. I removed R2 = 120 Om as shown on the picture. But no change in Interface behavior. I am posting also the log. Can anyone help, please?

thanks!
