1. What is the OBD2 Standard and Why is it Important?

The OBD2 standard is a set of rules and requirements ensuring vehicles can diagnose faults that might harm the environment. According to the Environmental Protection Agency (EPA), the OBD2 standard was primarily designed to prevent environmental damage, but it also aids in diagnosing various other vehicle faults.

The OBD2 standard includes both hardware and software requirements. For hardware, the mandatory presence of a standard 16-pin D-shaped diagnostic connector is crucial. This connector is where the ELM327 adapter plugs in. The software must support one of the following protocols:

• SAE J1850 VPM
• SAE J1850 PWM
• ISO 9141-2 / ISO 14230-4 KWP
• ISO 15765-4 CAN
• SAE J1939 CAN

The standard also regulates the list of possible queries and how their answers are deciphered. For instance, to find the engine speed, you perform a “010C” request. Each bit in the response equals 0.25 rpm. This standardization ensures any OBD2 scanner can communicate with any OBD2-compliant vehicle, making diagnostics universal and straightforward.

2. Which Cars Support the OBD2 Standard?

It’s a common misconception that all vehicles from the 1996 model year support this standard. Through extensive testing during the development of Car Scanner and feedback from thousands of users, we’ve gathered detailed information about OBD2 support.

In the USA, the OBD2 standard became mandatory for all cars made since 1996 for the US market.

In the European Union, the OBD2 standard, known as European OBD (EOBD), became mandatory for all gasoline (petrol) cars since 2001. Diesel vehicles sold in the EU have been required to comply since 2003.

In 2008, the standard became mandatory for all vehicles produced for the Chinese market.

Australia made the standard mandatory in 2005-2006.

It’s important to note that these regulations apply to cars produced for these markets, not necessarily cars made in these regions. For example, if a car is made in Japan but intended for the US market, it must support the OBD2 standard.

Japan does not mandate this standard for its domestic market. Therefore, right-hand drive (RHD) cars produced for the Japanese market usually do not support OBD2. However, if a Japanese manufacturer produces a car for the US, EU, or Chinese market, it will include OBD2 support.

In many other countries, OBD2 support is not mandatory. Whether a car supports OBD2 is at the discretion of the car manufacturer. Some cars produced for the European market before 2001 may support OBD2 because the manufacturer decided to include it for all markets. Conversely, some cars may have the OBD2 connector but lack the software support for the standard, especially in older European models.

3. How to Determine if Your Car is OBD2 Compliant?

Determining whether your car is OBD2 compliant involves checking a few key indicators. Here’s how you can verify your vehicle’s compatibility:
