This Gearwrench Auto Diagnostics Tablet Looks to Have it All

This Gearwrench bi-directional scanner tablet kit (GWSMART07) is the most advanced and featured OBD2 diagnostics package the brand offers.

It comes with a 7″ touchscreen tablet, wireless vehicle plug-in module, and USB-C charger.

Gearwrench packages everything in one of the nicest storage cases I’ve seen for a tool like this.

The Gearwrench GWSMART07 can do a lot – it has full OBD2 functions, such as reading and clearing trouble codes, diagnostic functions such as reading ECU information, and advanced functions such as displaying full topology mapping.

I had to look that last one up – the topology mapping enables visualization of the vehicle’s electronic network structure.

This is a far cry from the basic plug-in OBD2 scanners that connect to your phone or other mobile device.

The topology mapping feature is not available with Gearwrench’s basic or smart OBD2 wireless testers.

But besides that, you get a durable-looking Android-based touchscreen tablet.

I see this as a “I have a bunch of cars to troubleshoot” or “there are a lot of things wrong with the project car” type of tool, rather than a scanner for one-off “uh-oh, my check engine light came on, what’s wrong?” types of problems.

I handled the tablet and it definitely changed how I saw this kit. My mindset shifted away from “why not just use an iPad” to “now this is a dedicated auto diagnostic tool.” As mentioned, I’m impressed with the storage case.

Once registered, you get 3 years of free updates. Gearwrench says the scanner works with over 185 different car manufacturers.

Is this something you could use? Do you need more or less from an auto diagnostic tool?
