Getting Started with Vehicle Diagnostics

Diagnostic & Tracking Devices

Devices from Zubie, Automatic and several others offer a glimpse into the future of the connected car. These products offer you peace of mind by monitoring and tracking performance, providing up-to-the-minute vehicle diagnostics, and more. Compatible with most vehicles manufactured since 1996, these products plug into the diagnostic port underneath the steering wheel of your car.

Information is accessible through a smartphone app or Internet portal, providing you with constant, real-time updates and alerts. Besides identifying dashboard warning lights and giving you a heads-up to possible issues before they cost you big money, these simple-to-use, vehicle diagnostics devices can help improve both fuel efficiency and overall vehicle reliability.

Available Device Features

Vehicle Diagnostics: Daily engine health assessments can help you avoid breakdowns and catch potentially costly repairs before they get worse, while also reminding you of upcoming maintenance needs. They can also monitor engine, battery and systems health, and can even tell you what worrisome "check engine" lights mean, then turn them off once the problems are fixed.

Monitoring and Tracking Performance: With features like vehicle location updates and dangerous driving alerts, these devices allow you to monitor driving behavior. You can set check-in points so you are automatically alerted when your car arrives home, to work, school or other locations. You can also get alerted to potentially unsafe driving habits, such as excessive speed, hard braking, and rapid acceleration, or even get crash alerts with some models.

Other Features: Depending on the device you choose, you can also monitor your tire pressure, track mileage and trip history, get trip summaries, enable in-car Wi-Fi, and more.
