Vauxhall compatible OBD2 and ELM 327

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

Example for a 2005 Renault Scenic 1.9 dCi 120 hp

Just select the mode and enter the figures in the corresponding fields.

Here for Mode 1:
983B0011
B0000000

By entering the mode 1 figures in the PID decoder, we get a list of sensors that can be read:

• Calculated charge
• Coolant temperature
• Intake manifold pressure
• Engine speed
• Vehicle speed
• Intake air temperature
• Intake air flow, etc.

The principle is the same for the other modes.
