Please wait for connection
ECU Detected --> SAE J1850 PWM
If I go to trouble codes, I get a result of no trouble codes when I hit Read. This is only the demo version of Scanmaster though, and I doubt I can get much other info from a 2001 Focus anyway.
To get that result though, I pretty much need the following sequence:
1. ECU end of cable connected to ECU.
2. Ignition to on
3. Plug Serial end of ECU cable into the ELM.
4. Plug USB connection into ELM.
5. Attempt to connect with Scanmaster.
If I don't do that sequence, I just get ELM Interface not found :-/
Also decided to try it on my better half's Modus as well. Again most of the time does nothing (less can be said for the Modus though - it goes daft). Also fails to identify a protocol for the Modus.
Scanmaster is the only program to give any sign of life though. EasyOBD doesn't find an interface all the time, no matter what I do.
I'm reckoning my mate has been done.

Sounds lika a connector problem; Check the pins.

Are you sure your car is OBD2 compatible ? At my side I am more and more
convinced my 3-pin-DLC Honda Integra Type-R isn't.
But hey ..... if you have any doubt about the correct working of the ELM
interface itself just order another one for a few dollar or so .....
hi, i had the same issue as you guys, i installed the driver that came with the elm 327 from ebay and it didnt work so i googled it and found this site. i went to http://www.ftdichip.com/Drivers/VCP.htm
and installed the 2.04.06 drivers and it seems to be working fine now.
this is what i did:
1. uninstall the drivers that came on the cd with the "ebay elm327"
- the instructions on how to do this should be on the cd (mine were"
2. download the drivers from the link provided and unzip them in a folder that you can remember.
3. connect the elm to the usb port, it should say something like new device detected and the driver installation should pop up, instead of trying to load drivers from the "elm cd" select install from a specified location and select the folder with the newly downloaded drivers.
i then unplugged the elm and restarted the computer , then i connected it to the computer and launched the free scantool software, and it worked !!! you might not be as lucky but so far so good for me, i've used it on two cars today and it seems to be communicationg just fine. good luck
Same issue. Until now, only PCMSCAN can work and others like SCANMASTER, SCANTOOL still can not connected to car. Here is the detail.
1) Driver version above 1.0.2115 will not work. For example, the current new driver (version 2.4.16) fail to work
2) Even 1.0.2115, only PCMSCAN can connect to car. SCANTOOL, SCANMASTER report interface not found.
if some one can help....
I've got a ELM327 usb interface with FTDI232BL chip. I've installed the drivers on a laptop and it worked just fine. When I tried on my PDA (FS N520) , after I managed to install the drivers all I get when I connect to the car is the TX led flashing. What did I do wrong?
hello ，how are you ? hope everything is ok around you ,now we have one OBDII interface for truck ,can would pls let me know your brand of your truck ?
I'd like to share what I found to work. I had similar issues to others who have posted about the ebay/Hong Kong/Cheap ELM327 not working. After messing with it for quite some time here are the settings I settled on:
Install the drivers available online (google ELM327 drivers...these might be the same as the one on the disc)
Open the Device Manager and find the ELM device
Go to the Com tab and hit advanced
Make sure that baud here is set to 9600 and that flow control is set to "none"
In whatever program you are using to connect, set the correct com port and set the baud to 38400
Obviously, YMMV, but it worked for me in HyperTerminal, PuTTy, wOBD, and the Centrafuse app.
