Go to the car scanner for SMART

(1) - The digits between brackets (x3) correspond to the number of vehicles of the same type tested
(2) - Power in DIN horsepower (multiplied by 0.736 for the power in kW)
(3) - PID only supported for the main oxygen sensor (no.1)
Mode X column: A vehicle showing 00000000 on a mode means that no corresponding PID is active and that as a result the mode is supported but will not reply to any requests. None of the vehicles described below support mode 8.

If your vehicle is not in the table below, go to the next site also containing a list of vehicles tested. Note, the interface and protocol used as not all are supported by an ELM type interface. http://www.blafusel.de/obd/obd2_scanned.php

All compatible brands (in alphabetical order)

Interpreting table data

The tables on this page represent lists of vehicles that are compatible with the OBD standard (EOBD or OBD2 depending on the country). Compatible vehicles can be diagnosed using generic (multibrand) ELM327 interfaces.

Table utility

There are several uses:

• While the official dates for implementing the standard have been defined, manufacturers have implemented the standard more or less early. (See the official dates). The list can be used (if your vehicle is on it), to know in advance if you can buy an ELM interface and whether it will work with your vehicle.
• The second piece of useful information is the "level" of implementation of the standard. In general, the more recent your vehicle, the more diagnoses you can do on it. The tables list the support modes and their parameters.

How was this list written?

We asked the users of our EOBD-Facile software to help create this list by returning their "log" file of the connection to their vehicle. In exchange for this contribution, the software functions are available for free. The exact procedure is explained on the EOBD-Facile software page.

Understanding sets of figures in the tables

To understand these figures, corresponding to the parameters (PID), we have included a small program free of charge in our software. It is available from the file menu and PID Decoder
