Hello

I would to ask you for help. I bought ELM 327 mini Bluetooth and read all this forum but there isn´t this same interface. I tried to find resistor R04 or with signature 121 but without success Could somebody help me to find what I must remove in this interface?

Thank you.

Hello Tuner182

On your images you can hardly see anything
No caption read
Why does your Flash Mode, thus is nothing more Readable

Make again a better picture of the resistor R 34 with the chip next

I need to read the imprint

Hello Eddy

Hello Tuner182

Remove the Resistor in the blue Frame ( R 34)
than you can read the CAN Bus Protokoll with your ELM
Greetings Eddy

Hello Eddy

Thank you for your quick reaction. I removed the resistor R34 and tried to connect to CAN BUS protocol but still nothing. I didn´t have enough time, so i tried it only once. Today or tommorrow I will have much free time, so i will try it again and i will say you if it works or not.

Thank you

Hello Tuner182

Was your problem CAN bus ??

What car / controller you want to read?
check out:
- BT connection
- Drivers? not the driver using the Windows finds.

Hello Eddy

Maybe I found the problem. I have also wired version of ELM327. I modified it sometimes in the past by the instruction on this page. Propably it was your work thank you. That adapter works and I can connect to all control units in my car. I have Alfa Romeo 159 2.0 jtdm (year 2009). But with this BT adapter it not works I tried WIN XP also WIN 8. The bluetooth connection is OK also drivers. I used the newest version of Multiecuscan 2.2 also the older one 1.4 and without success. When I tested the adapter by function in Multiecuscan it showed me that this adaper is not compatible with elm v1.3. This version is 2.1. I took some pictures. Have you allready seen this problem?

Hi there,

I'm new in the forum and as everyone here, i've got a question for you guys.

I just rebuilt the engine of my Daewoo Rezzo (is the same engine of the Suzuki Forenza) and decided to scan the ECU to check any error. I just got my bluetooth ELM327 and after a few hours of trying several softwares (including Android apps) the thing can't connect to the ECU. The software/app can read the devide, but can´t connect to the ECU.

I just read about the resistor R04, i opened my devide and found out that's quite different to the ones i've seen here.

I'm 100% new with all this OBD scan system, so I hope you can give me hand here.

I send my thanks in advance!!
