FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

[ishipuri]

hello
This is what I posted yesterday
Red/yellow/blue cables supplied with the interface
No... my yellow cable to the item of the airbag
I was able to access
It's supposed to be red, right?
My problem is the airbag warning light
So I solved it for the time being・・・

OK　　sorry for bothering you

Hey guys. I've bought an ELM 327 v1.5 usb dongle from Aliexpress to use it with MultiEcuScan v5.0. The only interface that works with engine ECU is K-line, nothing more. Haven't yet opened it to check if it is trully a 1.5 version. I've tried to test other interfaces and kept responding timeout. Any ideas?

Hello
I share this link in case you need it.

https://es.aliexpress.com/item/1005004443781867.html?spm=a2g0o.order_list.order_list_main.10.74a8194d4wMkBS&gatewayAdapt=glo2esp

I bought this OBDII interface, and it works correctly for me, there are no changes to make it work.

It only cost me €18, I tried it on my Fiat Grande Punto 1.2, and it read the control units without problems.

The first thing I did was read which switchboards it had, and then I was accessing all of them without any problem.

In the attached image, highlighted in green, you can see the control units that I have, for the body computer you have to use the yellow adapter.

Hi,

I just bought this cable as you suggested, however when connecting to the service module, I'm getting a Can Bus Error. I've tried a couple of extra settings in MES but then I'm getting a timeout so I guess the settings are ok. Could you share your settings/drivers?
Thanks!

Kim

Is this issue also at the ELM 327 WiFi OBD Adapter?

Thanks in advance!

[cocofredo]

Hi, had a problem with my elm on a Fiat panda 1,1 8V MY2006
CAN problem when i tried dashboard connect or other modules apart the engine
I removed the 120 ohm resistor on my PCB and it works like a charm now .

[ytrufchev]

I have viecar Bluetooth 4.0 OBD2 protocol 1.5.
I need remove resistor 120 ohm in position image atached and jumper betwen pins 1,3,7,8 and 9,11, 12, dont make jumper in pins 1 and 9.

My car is Siena 1.0 year 2014 Brazil.
Instrument Panel Continental and engine module G4F.

I have free access from ALL modules, after modification in OBD with multiecuscan and AlfaOBD.
For Proxy aligment i select Strada 1.4 in multiecuscan, all rigth in my car.

Follow the link in Aliexpress, delivery in 13 days to Brazil.

Hi I just got the same ELM327 by Viecar, can you expaing about the jumpers, I can't understand it. Thanlk you.

[mattydr67]

Forget about jumpers. Use adapters especially if you wanna use Proxy Alignament.
Jumper just connect together some pins to make the interface comunicate with controlers on other pins the 7 (k-lin) or 6-14(CAN BUS)
The best ways is to use adpaters or as me an all-in-one adpater that let you manually multiplexing without changing the adpater by hand.

Good luck

[Infexis]

Hello, I have just bought ELM327 and new to Multiecuscan so I have a few questions.

First of all, my elm327 doesn't look the same as the others I've seen here on the forum, so I wonder which resistor should I remove.

Some other questions, why is the resistor being removed, is it to access can-modules? One other question is the ELM327 usable without the adapter cables & removing resistor. Because I got some errors trying connecting such as "WARNING: This interface is not compatible with ELM 327 1.3! Will not connect to any CAN module." and also problems when testing the connection in settings.

All help and answers are appreicated since I'm all noob to this.

Thanks in advance.
