Hi everyone,
Thanks a lot for this topic!
I bought recently a counterfeit adapter from aliexpress. I decided to dump it after OBD car doctor showed me a warning message and I read this topic.
Now it appeared that I can't even find a genuine ELM327 chip based adapter as all online sellers seem to offer a counterfeit.
Where could I buy a proper one ? any advises?
For example one could check PLX KiWi or OBD Link products. Thanks
Hello.
Purchased ELM 327 v.2.1 on Aliexpress.
Punto Auto = 2 / 1.2
Connection to the car and the pair ELM <> Lumia = no problem
On the program: "Diagnose your car" difficult to get a connection at the WP8.1 phone. At WP10 does not start.
How to connect it shows errors and lordling and all operating parameters of the engine.
But often causes going mad clock, reset, lock and start the car.
You must then remove the ELM and the car is booting up normally without problems.
On the program: "Car Scanner" is answered with no problem.
How to connect to it reads all the parameters offered by the program.
Tested on Lumia <> Punto 2 and the VW Golf +.
Program: OBD Auto Doctor does not start because of the WP10 in the phone.
Please note that the forum and site about "OBD Car Doctor", "OBD Auto Doctor" is different product from other company. Thanks!
Здравствуйте, нужна ваша консультация. Несколько дней назад приобрел elm 327 1.5 версия, подключали к infniti fx работало нормально использовал torque и scanmaster lite. Подключили к toyota camry 2004 torque подключился scanmaster lite нет. Примерно через 3-4 часа машина не завелась подключили другой сканер показал что заблокирован компьютер. С помощью этого сканера сбросили в стандартных установок сняли клеммы с АКБ и только тогда автомобиль завелся и то не с первого раза и делал очень тихо с перебоями. Возможно вы можете подсказать в чем проблема,также после этого перестал работать прикуриватель салона и подсветка прикуривателя. Хотелось узнать ваше мнение по этому поводу. Зарание спасибо
Скорее всего адаптер именно из серии китайских клонов о которых можно почитать выше в этой ветке. Некоторые недобросовестные продавцы могут перемаркировать их как 1.5, чтобы сказать что за адаптер нужно видеть отладочный лог и команды которые он не понимает. Как описывается выше в ветке некоторые машины могут быть более устойчивы к сигналам такого адаптера некоторые менее. Обычно сброс питания с ЭБУ должно лечить проблемы, реже требуется сброс при помощи сервисных специализированных сканеров. Остаточные проблемы с прикуривателем звучат странно, вероятно это просто совпадение. Спасибо!
I purchased 2 "budget" bluetooth OBD2 adapters which I have been disappointed with. I originally read this post about 6 months ago when I was having problems just after receiving them. I have tested these adapters out on at least 6 different vehicles. The only vehicle I have gotten both adapters to work on was a 2002 Kia Sportage (Hyundai). And with all software functionality. I am wondering if in particular parts of Asia where these are manufactured that they are using a different type of OBD2 compatibility than what our made-for-America vehicles are using? I don't have enough experience in that department to really know. I've had this adapter connect to every PC and mobile device via Bluetooth fine but when the ELM327 software is attempting to use all the protocols available, it is unable to connect to a Ford, Chrysler, or Chevrolet vehicle.
My adapters MAC address does not match the defective MAC listed in the original post.
Here's a few photos of my adapter(s). I did a quick tear down of the device. I compared the adapter teeth to my OBD2 scanner cable connector (which connects fine). The teeth in this adapter appear to be more recessed. They are also soldered in at such different lengths that perhaps there is a bad connection to the ECM when plugged in to most vehicles? Just a thought for those that have no functionality on their faulty or perhaps intentionally faulty Bluetooth adapters.
Update:
I took a look at the diagrams for the OBD2 pin configurations on typical OBD2 connectors. If anyone is interested, this unit is lacking pin #2 (J1850 Bus +) and pin #10 (J1850 Bus). It looks like several pins on OBD2 connectors are left for manufacturer specific features. This unit does not have any of those additional pins, as well as support for J1850, (assuming that I read the pin diagram properly). But if you read the case on the adapter, it "supports all OBD2 protocols"! SAE J1850 is listed as being used "mainly by US manufacturers". My assumption over these cheap adapters is that they were manufactured for the Asian or European vehicles in mind, hence the lack of the J1850 bus pins.
The pins that are present on my adapters; 4, 5, 6, 7, 8, 14, 15, and 16. Here's a chart for the OBD2 pin out configuration if you feel the need to pull your adapter apart to see what bus it supports. This is the car side of the adapter so you'll have to look at your pins in reverse.
Problem is deeper than only lack of contacts. Note!!! That now we are talking about cheap Chinese clones of ELM327, that have no relation to original product of ElmElectronics.com
Clones marked as versions 1.4 and 1.5 use functional analog of original PIC-chip(s) used by ElmElectronics (PIC18F25K80 + MCP2551) and stolen early version of original firmware (that was practically unchanged).
Clones marked as versions 2.1 use another chip (MCP2515 or other...) and other type firmware (own or strongly re-written) this combination appears to very raw and untested: it does not support a lot of required configuration AT-commands, some protocols could not be initiated, implementation of CAN signals could lead to on-bard electronics errors, etc.
By fact version 2.1 does not mean some unified product, looks like different manufactures try to fix (with better or not results) the firmware for own products. So it's really a big Zoo with quite a different a low predicted behavior under the unified name 2.1
I spent $10 USD for both but these adapters aren't worth even that purchase. Like you mentioned, INCARDOC, the official ELM chipset is much, much better overall. Spending the extra money to purchase a quality adapter is the best option in my opinion. The bluetooth connection drops out quite often on the adapter I posted above. But also, Bluetooth has been a very poor wireless connection for every device I use it for. Even the data transfer rates lack between every device i use it on. I also find that Windows is lacking in both driver and software support for Bluetooth. However, I have a quality USB OBD2 adapter that I use on my Windows PC and it is the best ELM327 device I have used till this day. I use the micro USB host adapter for that when running on Android and it seems to respond much quicker when recieving data from the vehicle.
A lot of people on here seemed to have negative experiences with clones ... I bought the Kiwi 3 OBD2 car to smartphone adapter from PLX's website a few months back and it has been working great– I just leave it plugged in and it autoconnects every time I enter my car. A little pricey but IMHO well worth the cost.
Hello everyone...
Posting here because maybe, just maybe someone will know something. I commented on the Torque forum too. About at my wits end here.
Here's the deal. I purchased one of these crappy generic adapters from BAFX. I didn't realize the harm I could do. I used this with Torque for quite some time on my 04 Chevy Cavalier. Well my brother had a check engine light in his 2003 Pontiac Grand Am for an engine misfire. Decided to figure it out and needed to reset the code. Well, I reset the code and now the engine won't crank. Tried the security relearn and replacing the ignition switch - which replaces the security sensor. My dad and I could get the engine started by starting it at the starter and it dies after a few seconds. Battery is good. So my question is, what component did the scanner most likely screw up? ECM, BCM, PCM???
Let me know folks! Learned my lesson that's for sure
Hi,
I've bought clone of the ELM327 adapter. Mac address is 00:1d:a5:68:98:8d and appears, that vendor is Polish company WB Electronics ( http://wb.com.pl/?lang=en).
Do you think, the adapter is safe to use?
Unfortunately it does not possible to say smth, w/o through tests. The most problems observed with "no-name" adapters where you have no info about the manufacturer. If you have exact information and contacts of manufacturer, just try contact them and ask your questions. Thanks!
Hello!
Any one know is this one is a good one? The last elm327 that i bought from aliexpress died after 2 weeks~~, I drive a mitsubishi ASX 1.6 2015 and the car is ok.

Vgate one one of the reliable solutions from lower-price segment.
An app that I've found really useful is "Elm327 Identifier". It really shows what your adapter supports and what you're missing because it doesn't support the latest standards. My Chinese made adapter which I bought years ago was fine when I bought it. I learned that I'm missing 7 pid's in version 1.4b, 3 in 2.0, and 2 in 2.1. I'm upgrading asap. BTW I tried the trial ofyour pro app and really liked it.
