What is the difference between OBD1 and OBD2 Honda?
The main difference between OBD1 and OBD2 in Honda vehicles lies in the diagnostic capabilities and the standardization of the systems. OBD1 was an earlier on-board diagnostics system, while OBD2 is a more advanced and standardized version that has been in use since the late 1990s.
What is OBD1?
OBD1, or On-Board Diagnostics 1, was an early on-board diagnostics system introduced by Honda and other automakers in the 1980s. This system was designed to monitor the vehicle's emissions and engine performance, and it could provide diagnostic trouble codes to help mechanics identify and fix issues. However, OBD1 was not standardized across different vehicle makes and models, so the diagnostic codes and procedures varied between manufacturers.
What is OBD2?
OBD2, or On-Board Diagnostics 2, is a more advanced and standardized version of the on-board diagnostics system. It was mandated by the U.S. Environmental Protection Agency (EPA) in 1996 and has since been adopted by automakers worldwide, including Honda. OBD2 uses a standardized set of diagnostic trouble codes and communication protocols, making it easier for mechanics to diagnose and repair issues across different vehicle makes and models.
Key Differences Between OBD1 and OBD2
- Standardization: OBD1 was not standardized, while OBD2 is a standardized system with a common set of diagnostic trouble codes and communication protocols.
- Diagnostic Capabilities: OBD1 had limited diagnostic capabilities, while OBD2 can provide more detailed information about the vehicle's systems and performance.
- Connector Location: OBD1 connectors were located in different places in the vehicle, while OBD2 connectors are located in a standardized location, usually under the dashboard.
- Emissions Monitoring: OBD1 primarily focused on emissions monitoring, while OBD2 monitors a wider range of vehicle systems, including engine performance, fuel efficiency, and more.
In summary, the key difference between OBD1 and OBD2 in Honda vehicles is the standardization and increased diagnostic capabilities of the OBD2 system, which has made it easier for mechanics to diagnose and repair issues across different Honda models.

What year did cars get OBD2?
1996
OBDII included a series of standardized diagnostic trouble codes (DTCs). 1996 — OBD-II becomes mandatory for all cars manufactured in the United States.
Will an OBD2 scanner read OBD1 codes?
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.
What year did Honda switch to OBD2?
The OBD-II standard became mandatory for the 1996 model year.
What vehicles use OBD1?
OBD stands for On-board diagnostics. The two main types of diagnostic systems in vehicles is OBD1 and OBD2. OBD1 was used in vehicles up to as late as 2006 and anything newer will be OBD2. Some vehicles manufactured earlier than 2006 are still OBD2 For example: You own a 2003 Toyota Corolla, this is OBD1.
How do I know what ecu I have in my Honda?
As further identification Honda ECUs have a software revision number inside the ECU. This is usually a two or three digit number stamped on the 28 pin ROM, or main processor. Accord and Prelude ECUs can use a letter and number code.
How do I know if I have OBD1 or OBD2?
A simple way to tell if ANY vehicle built for the US market is OBD. -II is it will have, (one only), 16 pin connector under the steering wheel, below the dash. No exceptions! it's federal law. OBD-I will have the scan tool interface connector under the hood, near the drivers side hood hinge and is a 6 pin connector.
Why is OBD1 better than OBD2?
Differences Between OBD1 and OBD2
OBD1 systems are more basic and less comprehensive than OBD2 systems. OBD1 systems typically only monitor emission control systems, while OBD2 systems monitor a wide range of engine and emission control systems, as well as other systems such as the transmission, ABS, and airbags.
