The OBD-II: What’s it Doing for You?
Ever notice your mechanic plugging into that little port under your car’s dashboard? That port is part of the on-board diagnostic (OBD) system, and it is playing a major role in minimizing pollution caused by cars. Devices plugged into the OBD port are also providing important insights and optimizing the driving experience, letting everyone leverage the connected car experience. Here’s a quick rundown of why it exists and how it could make car ownership a lot easier for you.
The OBD system was first introduced in the 60’s as a way to measure a vehicle’s emissions. Decades later, a more robust version known as the OBD-II was introduced, also able to monitor parts of the chassis and body. In 1996, amendments to the Clean Air Act required the OBD-II to be built into all light-duty vehicles (aka all cars available to consumers) as part of the Environmental Protection Agency’s attempts to reduce toxic emissions. If something in your engine malfunctions, your car might run just fine, but you could ultimately face expensive repair costs or unknowingly release toxins into the air like Benzene and Formaldehyde (potential human carcinogens). Because of this regulation, all cars will display a “check engine light” when something is wrong, so mechanics can plug into the OBD-II port to diagnose the problem.
Fast forward 20 years and the OBD system is proving to be an important factor in reducing the damaging effects of car emissions on our environment. Since the introduction of the Clean Air Act and the OBD requirement, toxic emissions have steadily decreased. Companies are also developing devices to use in tandem with the OBD-II port in all sorts of new and inventive ways. For example, our per-mile insurance customers plug the Metromile Pulse device into the OBD-II port to measure exact mileage. This enables us to provide low-mileage drivers with a fair insurance pricing model, since their monthly bill is based on the miles they actually drive, not just on a rough estimate. We also use the Pulse to decode those mysterious check engine lights without a mechanic, track driving stats and avoid street sweeping tickets. We’ve even used GPS functionality on the Pulse to help recover stolen cars!
Fleet management services are using OBD devices as well, allowing them to communicate with their vehicles in real-time and monitoring things like location, speed and driver behavior. With a recent Deloitte survey finding that 72% of smartphone users see value in connected car technology, we expect to see additional use cases of OBD devices in the near future.
