Launch X431 V Bi-directional Scan Tool Review on Jeep Liberty 2005
Auto Diagnostic Tools / July 28, 2021

All right I’m going to do a review of the LAUNCH X431 V I just purchased. This is a automotive scanning tool that is a huge upgrade. Prior to this, a lot of my work was done with something small and expensive like this, just a cheap WIFI or Bluetooth scanning device. It’ll scan the code but it’s not bi-directional. In other words, it does not let you control any of the systems of the vehicle. I have so many vehicles that I work on and it’s so many of the systems are not available to be scanned or diagnosed through, so I finally invested in a fairly highly-rated device from Launch. I’ve already put quite a bit of work into this. So it comes in this wonderful molded case. Inside you’ve got the main tablet itself. This is the actual OBDII plug-in module that talks in a wireless way through Bluetooth to this tablet. And you have all kinds of connectors specific to different vehicles. There are just different cables, like clamps for getting power if you need auxiliary power. Let’s take the tablet and VCI through a simple test. We’re doing this Jeep Liberty 2005 today. This car…
