Connect your Elm327. (16-pin diagnostic connector of your car)
-In all cars after 2001 there is such a connector.
-Usually sits on the driver's side, in or under the dashboard.
-Sometimes behind the ashtray.
-Sometimes in the tunnel console.

 

Do NOT put your ignition on.
Your Elm327 already has enough voltage to be able to test.

 

Start ElmAllObd.
Select Menu >Test Interface >TEST
Select your interface from the list.
ElmAllObd tries to connect to your Elm327.
If ElmAllObd can connect to your Elm327 then:

 

During the test:
1: ElmAllObd sends several commands to your Elm327.
All the commands that I needed to properly set up the interface.
To determine whether your interface is suitable for all Ecu's I have tested.

 

2: ElmAllObd sends the commands with a certain speed and duration between them.
To determine if your Elm327 interface is fast enough.

 

3: ElmAllObd asks the supported protocols.
To determine which car brands are possible.

 

4: ElmAllObd asks the Elm327 version.

 

 

 

If on the ElmAllObd interface test page all commands have been answered with "OK",
then you have probably purchased a good Elm327 interface.

 

Sometimes a "hidden" Elm327 v1.0
On the Tested Elm327 page there are two tested Elm interfaces.

(A the lower one) and D
You can only really test this Elm327 by checking whether a Ecu can actually be read.
You can try this with one of the many brand-specific apps that are available.


If you cannot find a brand-specific app for your car brand, or if it does not exist, then you have one other option.

 

ElmAllObd Server
Then you can try to test your Elm327 interface by using my server.
You may choose one of the Ecu's I have tested that you would like to use for the test.
