Basic OBD2 Diagnostics works for all car brands that use the CAN-bus (Controller Area Network) protocol. This protocol operates on a message-based system, allowing different vehicle control units to communicate with each other and relay information about their statuses.

Most newer car models (from 2008 onwards) support the CAN-bus protocol. To check if your car supports this protocol, follow these steps:

1. Find the OBD2 port. It's typically found near the steering wheel. We have a detailed article on how to locate your car's OBD2 port.

2. Examine the port. Check if it has a total of 16 pins.

3. Look for 6th and 14th pins. These pins indicate that your vehicle has CAN-bus wiring. Refer to the image below for guidance.

Keep in mind that the pinout may differ for different vehicles depending on communication protocols. However, if the 6th and 14th pins are present, your vehicle supports the CAN-bus protocol.
