Attention "bad" adapters!

We faced the problem, that some adapters (often the cheapest ones), can’t connect to the car's ECU.

 

The reason is using of "bad made" clones of ELM327 instead of original chipset and firmware from Elmelectronics. You could notice potentially problematic adapters by: very low price, by MAC address (one can see it while connecting and searching for the device, so the adapter’s name will be detected and its MAC address) .

 

If the MAC address of your adapter

  1. starts with the numbers 66:35:56: ...  or 88:35:56:...(for example, 66: 35: 56: 78: 90: AB)

 

  • or 00:00:00:00:00:01
  • or AA:BB:CC:11:22:33
  • or 00:00:00:11:11:11 (fresh example from 2018 garbage collection, marked as version 1.5)
  • or some other "strange looking" addresses

- be prepared that this adapter could fail to connect, support not all protocols, fail to read some data and what's more, they can cause problems with your car.

 

There are also some adapters that might be almost good while working with single ECU and short commands, but cold fail to get reliable results for cars with 2 and more ECUs and "long" commands like VIN or DTC readings. One of this could have followingg MACs:

00:1D:A5:68:98:8A or ​00:1D:A5:68:98:8C 

As well, there might be problems with other "no-name" Chinese adapters marked ELM327 v2.1.

Please follow the discussion below to get idea about the issues, ask questions and share your observations.

 

We ask to share with us the names, photos, links to these adapters to make a "black list" of such devices.

I have an adapter with the above mentioned Mac address and I leave it plugged into my 2007 acura Tl with a android Tesla style screen, and I have zero issues with the device. It has properly diagnosed my issues with my car. So what exactly are you saying about these adapters? Are you saying that they will do more damage than good?

To add to the wall of shame:  https://www.ebay.com/itm/263860402148
An obviously suspect cheap bluetooth ELM237 2.1 type MAC 00:10:CC:4F:36:03. Checked on Opel Astra J of an uneducated friend. Caused the ECU to power off (?) putting the car into some sort of limp mode, ESP, power steering and check engine warnings popped up.
The funny thing is a single fault is indeed found in the app, it is ECU disconnect event. It cannot be cleared, since it disconnects
Luckily after a few minutes powered off it can be started and driven normally, but with the check engine light on.

Purchased a Nexpow OBD2 Scanner Bluetooth from Amazon. After a few minutes pairing the device to my phone, I was able to connect with incardoc app and Torque (lite) with no problems. The only limitations are the free version of the apps. My only recommendation is purchase the Pro/upgraded apps, not to play with advanced settings and associated PIDs in the app. Read the guide before going too deep.

I bought this adapter (ELM327 v.2.1) and just tested it on my Opel Astra H.

It works fine - I saw some dynamic parameters (RPM, Temp of Cooling Liquid)

The connection was good.

The seller of this product is http://ru.aliexpress.com/item/2014-Newest-Super-Mini-ELM327-Bluetooth-with-Power-Switch-CAN-BUS-OBDII-ELM-327-Work-on/1852873392.html?recommendVersion=1

Maybe this version of the item is good. Unfortunately I can't say it's MAC address for now.

The smartphone is Alcatel Idol 2 mini S 6036Y

Thank You admin for your help in this section i want just check this store is officiel for vgate or not https://fr.aliexpress.com/store/4576039 Thank you alot 

 

Unfortunately it's hard to identify "real" Vgate from thousands of clones. Ref. page does not give direct mail or site contacts to validate the seller. You might try to find contacts and ask about brand owner company "HK Vgate Technology Co., Ltd" 

Thanks!

It would be much helpful if post here the exact quote of the answer. Usually answer suggest exact steps and request to send us the log after running the suggested steps.
We have no "other" app to sell you, the one you are using is THE ONLY.


Thank you for the understanding and exact following the recommendations.

Reclamei no desenvolvedor do meu sofware que meu adaptador não estava mais funcionando no celular e a resposta foi qie posso estar usando um OBD falsificado. Meu adptador OBD funcionou muito bem, com esse software, e simplesmente esta todo confuso, do nada, então creio que isso é para me vender outro software, já que deve ter um ano da compra do anterior.

I bought elm327 wifi obd2 adapter for 130 sek (12 dollars). Tried it on my volvo v70 my2010. Connected to iphone but no connection to ecu. Suddenly a lot of error messages were presented in combined instrument and engine stopped. Not possible to eject key and startbutton was not working. Luckely when removing the elm327 from obd outlet , it was possible to start the car again. Do not know the version of the elm327. The elm327 device was good food for the trashcan.

Please note, that app inCarDoc by default reads only parameters that exposed by your car according to OBD-II standard specification. Standard does not support the most of specific to EV or Hybrid cars parameters including the Battery voltage.
Those parameters does not covered with any standards and their reading possible only with apps or extending setting, specific for the appropriate car-model. 


You might need to search apps or extensions, that exactly declares reading of battery related parameters for Toyota Prius 2008.

Thanks!

Absolutely agree... and we stated near the same, if teview the thread. Now doezens of Chinese factories sell different products with different characteristics and quality, but packed and labeled as Vgate. The same for other brands as well.
