Overview
DIY mechanics and small shop techs get a scanner module that turns their smart device into a bi-directional diagnostic tool. Plug it into the port, open the app, and run live actuation tests, resets and data captures.
No subscription fees for updates is the strong point, and full bi-directional control covers jobs like ABS bleeding and throttle matching. Detail is thin on supported devices and protocols, and the manufacturer count differs between title and description.
Who it's for
Weekend wrenchers and small shops that already carry a tablet will get bi-directional work with no yearly fees. Users who want a rugged all in one handheld should look elsewhere.
Pros and cons
- No subscription for updates
- Bi-directional actuation tests
- Common resets like TPMS and ABS bleed
- Very small and light
- Needs your own smart device
- Supported protocols not listed
- Conflicting manufacturer counts
Performance notes
Results depend on the app and the device it runs on, since the module only bridges the car to the phone or tablet. Bi-directional control lets you command parts on and off to confirm a fault. Reset coverage depends on the vehicle make and model.
