Will any OBD2 scanner work on any car?
The short answer is no, not all OBD2 scanners are compatible with every vehicle. While the OBD2 standard was introduced to provide a universal diagnostic system, there are still some variations in how it is implemented across different car makes and models. To ensure compatibility, it's important to choose an OBD2 scanner that is specifically designed to work with your vehicle.
Understanding OBD2 Compatibility
The OBD2 (On-Board Diagnostics 2) standard was introduced in the 1990s to provide a standardized way for mechanics and car owners to access and diagnose a vehicle's computer systems. This system uses a standardized connector and communication protocols, allowing for the use of universal OBD2 scanners.
However, while the OBD2 standard is meant to be universal, there are still some variations in how it is implemented across different car makes and models. Factors such as the specific communication protocols used, the types of diagnostic trouble codes (DTCs) reported, and the available data parameters can all vary between vehicles.
Choosing the Right OBD2 Scanner
- Check for vehicle compatibility: When purchasing an OBD2 scanner, it's important to ensure that it is compatible with your specific make, model, and year of vehicle. Many scanners are designed to work with a wide range of vehicles, but it's always best to double-check the manufacturer's compatibility list.
- Consider the scanner's features: Different OBD2 scanners offer varying levels of functionality, from basic code reading to more advanced features like live data monitoring and diagnostic trouble code clearing. Choose a scanner that meets your specific needs and requirements.
- Look for manufacturer-specific support: Some OBD2 scanners are designed to work more seamlessly with specific car brands, offering enhanced functionality and support for manufacturer-specific diagnostic codes and data parameters.
By choosing an OBD2 scanner that is compatible with your vehicle and offers the features you need, you can ensure that you can effectively diagnose and troubleshoot any issues that may arise with your car.
Do all OBD scanners work on all cars?
Some older or foreign cars might have different systems that are not fully compatible with all OBD2 scanners. Different car manufacturers use various protocols like ISO 9141, KWP2000, J1850 PWM, J1850 VPW, and CAN. While most modern scanners support these protocols, some cheaper models might not.
How do I know if my vehicle is OBD-2 compatible?
Additionally, a small number of 1994 and 1995 model year gasoline vehicles were equipped with OBD II systems. To verify that your vehicle is equipped with OBD II, you can look for the words "OBD II" on the emission control information label attached to the underside of the vehicle hood.
Will a cheap OBD-2 scanner work?
The cheapest scanners are just an ELM327 clone that can talk CAN only. More expensive tools might be able to hit the older OBD2 interfaces (K-line, etc.) as well. Generally the more you pay the better quality of hardware as well, including protection circuits, etc. After that thoughit's all software.
Are OBD2 readers universal?
Even though OBD2 is a universal standard, it can happen that a scanner is not compatible or doesn't work well with your vehicle. So we recommend you check whether your chosen OBD scanner is compatible with your vehicle.
What is the difference between OBD and OBD2?
OBD-I vs. OBD-II. The central difference between first generation OBD systems and OBD-II is that OBD-II systems are now homogenized into the vehicle itself. Unlike OBD-I, wherein diagnostic systems were externally linked to a vehicle's console.
Can you use an OBD-2 on any car?
OBD ports have been fitted to all petrol passenger cars sold since 1 January 2001 and all diesels from 2004. This 16-pin socket is referred to as OBD2 outside of Europe and EOBD in Europe.

Can I use my phone as a car code reader?
OBD Fusion® is an app for iPhone, iPad, iPod Touch, and Android that allows you to read diagnostic data from your vehicle. You can create virtual dashboards showing multiple vehicle sensors, estimate fuel economy, read diagnostic trouble codes, and turn off your check engine light.
What is the difference between an OBD2 reader and a OBD2 scanner?
There's a big difference between basic code readers and full-fledged scanners in that scanners can access enhanced OEM (Original Equipment Manufacturer) codes that are manufacturer-specific. These scanners don't use the standard OBD-II protocol to communicate with the car's modules.
