FAULTY ELM 327 INTERFACES DE-MYSTIFIED (READ HERE)

Hello

@ obdspecalist

This one also

and to an better price

Greeting Eddy

This is a chinese clone with no warranty for CAN LINES

Hello

This is not correct

It is important whether a bridge resistor is installed
And which software is fired to the PIC.

I bought 3 years ago many of this interface and a CAN bus
Switch. 6/14 to 1/9

Please guys any help here viewtopic.php?f=5&t=1493&start=2190#p17984

hey guys,

any help with this interface i will appreciate it, i can only connect to ecu engine.




Thx

Hello
And always the same questions !!!!

What vehicle?
What year?
What control?
What driver was installed?


Since the resistor only interferes with CAN bus protocols with multiecuscan.
Ergo:
No CAN bus
no problem

Greeting Eddy

What vehicle? Peugeot 307 HDI 1.6 110cv
What year? 2006
What control? i think VAN
What driver was installed? Bluethoot "Torque"

I don't understand but it must work with all vehicles, right?

Hello

Sorry but with Multiecuscan you can not control your Peugot and thus a bridge resistor has nothing to do with your problem.

Torque is the software and no driver !!

Whether Torque at all Peugot controls can read I do not know.
For this you have to read in the various Peugot forums

I only use the Peugot a medium CAN (3/10), for some controls.

Hi, here is how to remove the termination resistor:

Find it: follow PCB tracks from OBD connector pins 6 or 14, they connect to chip U3 pins 5 & 6.
On the chip is also connected to pins 5 & 6 the resistor R34, this is the (wrong) termination resistance, unsolder it !

This should solve your CAN communication issue, but as said by others, not sure about what will be read from your Peugeot...

Regards, Bernie

Hallo.

I've a elm 327 v. 1.4 inteface.I use it for 4 years.I can'not read body comp,steeringweel,service modul,etc. just motor ecu.The problem exists in one month.Nothing is changed.With wag kkl cable does not work, just motor ecu can be read.I've a frend and he has the same problem. We have MES2.2 and AlfaObd program and we have the same problem with them.Any tips what could be the problem?

I have one of these cheap ELM 327's and was having little success in getting it to connect to the car. I had scanned the connection to get the correct port settings and was about to give up when quite by chance I discovered that I could connect every time by hitting connect 1 second after turning the key while all the warning lights where on. And when I tried it after all the light had settled down and low and behold NO Connection.

Hi everybody
Sorry for my english, I´m not so good

I´ve got an ELM327 interface and I can connect to ECU, but I can´t connect with the service reset or instrumental panel. I have a punto international and a grand siena. In both of them I can read and check ecu and errors, delete them and use actuators and adjustments. I ´ve spent a lot of time reading these posts but I don´t know what to do, should buy a new Elm device or fix (how?) this one. Also FES dashboard didn´t work too. A pictures of the device and the connections.
Thanks a lot.

[PuntoBlackMotion]

Another two pictures. Thanks again !

Hello

For a hundred times

What vehicle?
Which model ?
What year?

And here is an interface test with MES here to see
Which interface you use.


Should it be an older ELM (> 2015) remove R2 (121) if you're lucky
Then you can create a connection

Thanks Alfaeddy

It´s true I forgot a part of information

The Punto is a punto international 1.6 16v 2016 (etorq)
The Grand Siena is a essense 1.6 16v 2014 (etorq)

Both of them have the same ECU (engine) and the EML327 device works OK
In the rest of the modules are diferent, but I can scan a big part of them with your solution (fixing the device)
I could reset service in both cars.

Thanks you a lot, bye
