OBD1 vehicles vs OBD2 vehicles

OBD1 (On-Board Diagnostics 1) vehicles and OBD2 (On-Board Diagnostics 2) vehicles refer to the differences in diagnostic systems of cars produced in different periods.

OBD2 vehicles appeared after 1996. There are new unified standards for diagnostic interfaces, fault codes and data output. The OBD2 protocol also provides better working tools and experience for car owners and technicians.

What is an OBD1 scanner?

The more powerful OBD2 scanner can also use the OBD1 adapter cable to scan and diagnose OBD1 vehicles.

Can I use an OBD2 scanner on an OBD1 port?

In order to connect the OBD2 scanner to diagnose the OBD1 vehicles, the tools for adapting the different connectors to the standard OBD2 interface would be necessary, and then loaded with the proper software, the scanner can read the different sets of OBD1 data and protocols for the vehicles.

Where is the OBD1 diagnostic port located on my vehicle?

The location of the OBD1 diagnostic port varies by vehicle, but is usually located under the dashboard, near the steering column, or in the engine compartment.
