The ECU collects input from sensors like oxygen sensors, mass airflow sensors , and voltage sensors and then uses it to control actuators like fuel injectors and hydraulic cylinders to get the desired performance.

Now when the light comes on, you use a car diagnostic tool to access the ECU and check sensors and actuators for faults. Developed in the s, they were made by automakers for their own cars. Meaning there was an OBD1 scanner for each brand.

You can imagine the number of scanners a mechanic needed to have at any given time! Generally, the OBD1 system features protocols, hardware interfaces, and proprietary connectors. Nowadays there are OBD1 car diagnostic tools that support multiple protocols.

You only need to buy adapter cables for all the different vehicle makes that you want to run diagnostics on. Despite the effort, it was still lacking in functionality. OBD2 was first introduced in vehicles made in It became a mandatory requirement for all cars and light trucks made from onward.

This system basically features a set of standards that describe how a car diagnostic tool and ECU interchange digital information. As such, they come with an OBD2 port — usually located just below the dashboard — where an OBD2 car diagnostic tool plugs. While both systems are similar in primary functionality, they vary widely in many other ways.

But how exactly are they similar? To put it simply, they both check sensors and actuators for such things as shorts, opens, and high resistance. In terms of differences, the first is when each one was implemented. The 5-year difference also saw several improvements in functionality. For starters, the original OBD only targeted emission control of a vehicle. Even so, it was not really effective in getting motorists to move their emission handle system tests.

On the other hand, OBD2 has enhanced signaling protocols that read a wide array of emission parameters at a go. Our website uses cookies. If you are happy for us to do so, just click Close. For full details of the cookies we use and how we use them, or to change your settings please see this page.
