The Panlong WiFi OBD2 device is a scan tool for diagnosing car problems with a iPhone or iPad.
The free version works well enough for simply scanning for codes which will be displayed if there is any.
The Panlong WiFi OBDII scanner is a good low cost option for those looking to troubleshoot their car computer with their iOS device.
Android smartphones and tablets can also be used.
The Panlong is not meant for high end use but more for the home mechanic DIY type person.
It can find a problem on vehicles 1996 and newer and display the codes which in turn can be looked up.
Finding the error code online is easy and often leads to insight on how to fix the problem and the steps necessary to do it.
It also can be used by someone who simply wants more information on a problem before going to a mechanic.
The Panlong is a good unit for the cost and it ability. The paid versions of the apps it uses likely give more features that I wasn’t able to use.
As always read the reviews on Amazon, forums, or elsewhere to be sure it is a good fit for you.
