An OBDII scan tool is one of those things that can make a real difference to a DIY mechanic or a car owner.
For example, a car owner can use a low-cost OBDII scan tool to find the problem causing it to run badly or an engine light to come on.
A mechanic can use the same tool to diagnose a mechanical problem and repair it.
This has huge benefits for a car owner or a backyard DIY mechanic looking to save money.
A vehicle owner can also research the cost for repairs on a bad part before ever talking to a mechanic.
All of this can be done very cheaply, making them affordable to almost anyone.
How Does a Bluetooth Scan Tool Work?
A wireless scan tool is plugged into the OBDII connector in a car or truck.
OBDII ports are usually located on the driver side under the dashboard on any vehicle 1996 and newer.
The OBDII scan tool transmits a Bluetooth signal to a smartphone or tablet, which communicates with an app.
The app will communicate with the vehicle’s computer and display any codes with the app translating any problem a car may be having.
Most apps have many more options than diagnosing problems. For example, they can also display RPM, speed, oil pressure, and much more.
So which scan tool is the best for an Android smartphone or tablet?
There are many units available, with some of our favorite picks below.
As always, be sure to read the reviews on Amazon or elsewhere to be sure a unit is a good fit for you.
