HH OBD Bluetooth adapter isn't in the same class as the scan tool your mechanic uses, but it could very well turn out to be the most valuable player in your own toolbox. The downside, in comparison to more expensive scan tools, is that it isn't a standalone device. Like all ELM327 scanners, what it does is provide a connection between your car and a smartphone, tablet or laptop, which does the actual heavy lifting.



The good news is that most people already own some type of hardware that's compatible with the HH OBD ELM327 scanner, and if you fall into that category, the device will provide you with on-demand access to the trouble codes and PIDs you need to diagnose all types of problems.


The Good of HH OBD

There are a lot of OBD-II interface devices out there that use the ELM327 microcontroller, but they don't all have the same build quality. Some of these devices are notorious for failing to pair via Bluetooth, but the HH OBD ELM327 Bluetooth scanner seems to have a pretty solid build quality. 

The device itself is easy to use, and data transfer is snappy after you have it paired. It's probably the cheapest way you'll find to read and clear trouble codes, and it also provides access to a wealth of sensor data. You can use that to perform your own diagnostics, but it's also fun to play around with.

If you have an Android phone or tablet, there are a number of apps that can read and display OBD-II sensor data. That can allow you to use your tablet as a replacement instrument cluster if you want, or you can zero in on one data stream to help with a sticky diagnosis.
