Q1: what is the difference for the v1.5 elm327, the plastic elm327 and the bluetooth elm327?
A1:There are the same functions for them,the only different is the interface:the v1.5elm327 has both usb com interface,the plastic elm327 just has usb interface, and the bluetooth elm327 just has no cable ,it works by the bluetooth.

Q2: I found an icon written on elm327 TEST, when I press this button, it says (This soft wear not installed on this version). I want to know is the TEST icon means that it will give me reports about the defects of the car or not. If it gives report I believe that this will be easily for ordinary person.
Please send to me a demo for the TEST soft wear to revise.
Also there is icon named Freeze frame, what does it mean?
A2:yeah, elm327 “TEST” icon is car test function, but why it says “Display mode 5,6,&7 test results(not implemented in this version”, because you did not set elm 327 COM Port. Go to EXIT from elm327 test screen before change the COM Port number, then how to set the COM port, under the elm327 software, there is a file folder named “USB Driver”, open it you will find a PDF file named "ComPort.PDF”, it tells you how to Changing the COM Port Number, the following parts is a short instruction :

Q:I know nothing about OBD, but am interested in getting a device to read codes, between me and my brother. I came across this what do you think? Or would any of you lot have an idea what to buy for not much money?

A:Question is - what You want to read. If only something (fault codes only)from engine management system - You can do that with this tool. If You want to read something from other systems - like ABS, Airbag etc. - that tool can't do this. Tool seems good, but I would prefer one with USB lead.For which car You suppose to use it?

Q: thanks for the replies.Basically, we would like one to read the fault codes, and re-set them if possible.We would like one that reads all cars 2003 and younger. I did read that OBD2 was a standard all cars had after a certain year, but I stand to be corrected.I say all cars, at the moment I have a Laguna, and my Bro a Rover 45, but I will be changing mine soon so was after something universal..ish.I saw that item with Bluetooth, because I have an android phone and there are apps to use this with. A USB would be ok too, if I could get software easy enough.
Any recommendations?

A:For 2003 and newer cars you can use the scan tool you found (elm 327 based i guess). It is limited to engine and a little bit transmission, but can read and clear fault codes for that, but that is true for all cheap universal scanners.For elm based obdII tools there are alot of good pc-software like scanmaster, scanxl, digimoto... I don't know if the android app is good, too. If you want to read codes from other systems (abs, airbag...) then you need other tools, but the universal ones are expensive (launch x431, autoboss...). A good cheap universal tool seems to be the autel maxidiag 70x (obdII and abs/airbag for many cars 'til 2008).

A: Warning, bluetooth interface make many problems (we had diskussion on DK). Better for you is classic cable interface. Latest version ELM327 is v1.4a and work very fine. KKL interface is some limited in ecu scaning. For your scan, read, and clear fault code, is better ELM327v.1.4a. Bay only USB inetface becaus modern laptop havan't rs232.
