How Can You Tell the Difference Between OBD1 and OBD2? This is why it is sometimes referred to as a full-feature scanner.
The OBD2 has a lot more universal appeal because it is a lot more reliable thanks to its wider compatibility. The OBD1 has to be corded at all times to work while the OBD2 can be connected wirelessly through Bluetooth or Wi-Fi. The OBD2 has more and better-standardized vehicle protocols and a system that checks and validates the data. The OBD2 scan tool is a more advanced technology when compared to the OBD1. There are emulators in the market that can read data from over 700 cars.

However, with the use of an emulator, it is possible to use an OBD2 scanner as a code reader for data from an OBD1 scanner. It is not possible for an OBD2 scanner to readily read codes from an OBD1 scanner because they use different technology. This means that the data that comes from an OBD1 scanner cannot be used in complex diagnostics or even for monitoring various gauges in real-time. As for OBD1, their systems can only record up to 300 data parameters compared to the over 15,000 possible parameters recorded by an OBD2 scanner. The differences in these systems are also apparent in the kind of data it manages. The connectors, pins, bus communicators, and even error codes can vary greatly from one manufacturer to another. This makes these two systems largely incompatible. OBD2 compatible cars use standardized protocols for communications while OBD1 cars use specific protocols for communication. Over the years, the technology has developed to include more standardized information on vehicles.
The earliest OBD systems were used to turn on the car malfunction lights such as the dreaded engine light. OBD stands for onboard diagnostics, which is a system that scans the entire vehicle using an onboard computer.
