  • what is the difference between OBD-1 and OBD-2 and is there such a thing as OBD3?

    You are here: Home » FQA » what is the difference between OBD-1 and OBD-2 and is there such a thing as OBD3?

    obd1 is 95 and older and obd2 is 96 and newer. altough some early and mid 90’s vehicles were obd2 compatible. there is talk to obd3. Its almost like big brother for vehicles. Your vehicle will transmit a signal if your vehicle has an emmissions fault. a transponder(built into a stop sign or stop light for example) picks up the signal and your are then later sent a notice. Its all just talk for now. But im sure theres much more to it. the difference between the two is SAE got involved and set a standard to on board diagnostics (OBD). for example a code p0300 is : random misfire. P0300 is the same for a toyota honda chevy ford chysler etc. A P0xxx code is the same for all OBD2 vehicles no matter what make and model. But a P1xxx is a manufacturer specific code for a more indepth code for more accurt diagnostics. Also on obd2 vehicles the diagnostic data link was required to be located under the dash driver side dash board. obd1 it could be located anywhere on the vehicle. OBD2 also has the added feature of real-time data and freeze frame data.

    When you’re buying a vehicle, two terms that will often confuse you are OBD1 and OBD2. Naturally, these will be taken in the automotive context.

    The acronym refers to On-Board Diagnostics. Basically, it defines a vehicle’s capability to diagnose, or report itself. For example, if you have a high-tech OBD system in your

    car, and it has a problem, the OBD system will be the one to self-diagnose, or ‘tell’ the repair technician what is wrong with the engine.

    With advancements in technology, came the improvements of OBD systems, and the latest ones use a standardized digital communications port that provides real-time data. This

    results in faster diagnostics of a vehicle’s problem, and more efficient remedies can be provided for the problem.

    Now, here’s the difference between OBD1 and OBD2. With OBD1, the goal was to develop a diagnostics system which focuses on the emission control systems of a vehicle. When it

    came to its effectiveness, the OBD1 was not really that successful in forcing drivers to pass the emission control system’s test.

    OBD2, on the other hand, is a definite improvement to the OBD1. OBD2 has better signalling protocols and messaging formats. When used in emission control system tests, it can

    provide better results for a vehicle’s parameters.

    Meanwhile, when considering their manufacturing dates, OBD1s were introduced long before the OBD2 models, which only started in the early 1990′s. The OBD2 is a better system,

    in the sense that it provides standardized trouble codes for car owners who experience engine problems.

    Finally, OBD1 is typically connected to the console, so that the port can be diagnosed and data can be read. OBD2 is remotely used to diagnose ports, and reads data through a

    Bluetooth connection. As such, it is easier to diagnose a problem remotely if you have a car made with an OBD2 system.


    1. OBD1 is connected to the console of a car, while OBD2 is remotely connected to the vehicle.

    2. OBD1 was used during the earlier years of the car manufacturing industry, while OBD2 was only introduced in car models produced in the early 1990′s.

    3. OBD1 has good diagnostic capabilities, while OBD2 has better signalling protocols and messaging formats.

    OBD 1 is 1996 or older. OBD 2 is 1996 or newer. No such thing as OBD 3. Also OBD 1 was for certain cars. OBD 2 is global. But it is better because it has a program called pathfinder that will search for codes using year make and model where the global edition of it shows codes for any car.

    OBD 1 was manufacturer proprietary, there where different plugs for different cars, you cannot use a OBD2 on and OBD1 because the data is handled differently

    The difference between OBD-1 and OBD-2 is that it’s completely different. If you know what I mean.

    The only academic difference I can think of is that OBD-2 was somewhat standardized among all the automakers, where OBD-1 wasn’t.
