Which vehicles the Thinkscan 689 actually covers
The Thinkscan 689 is a shop-grade diagnostic tablet built for mechanics, with coverage listed for over 140 brands and all available vehicle modules. If you run a repair business, that breadth is the reason to consider this over a hand-held code reader.
One check matters most before you buy. The maker says compatibility varies by car model, and they recommend emailing your VIN to confirm the service functions work on your specific vehicles. We'd consider that confirmation step essential rather than optional, because a scanner that won't run your reset routines on a given model can't earn its place on the bench.

What the Thinkscan 689 does and what it cannot promise
This is a scanning and control tool. It can read and clear codes across systems, run live data, and send bidirectional commands to components like the radiator fan, throttle, mirrors and door lock actuators.
The maker states there are no annual fees, a real advantage for a busy shop. FCA AutoAuth, however, is a third-party service and may carry an additional cost, so budget for that separately if you work on FCA vehicles. ECU coding and component matching are supported, but a scan never substitutes for the repair itself.
We'd consider it a sensible buy for shops that want dealer-level functions without paying renew fees each year.
What it will not do is guarantee any repair outcome; it is a diagnostic and control tool.

At $375.23, the Thinkscan 689 sits $93.71 below its typical price over the last 90 days of $468.94, a 20 percent gap. That window is a fair benchmark for a tool that sees regular discounting.
The discount is a pricing event only; nothing about it says the tool diagnoses any particular fault or makes a vehicle safe to operate.
Power, protocol and connection checks before first use
Charge the tablet fully for at least 30 minutes with the included Type-C cable before its first power-on. The maker notes that if the screen stays dark after charging, you should reconnect and let the full 30-minute cycle finish to prime the battery.
Confirm that your vehicle's diagnostic protocol is supported, since this scanner lists CANFD and DOIP, plus FCA AutoAuth through that third-party service. The device runs Android 10 on a 4-core processor with 64G memory and a 4150mAh battery, so the practical checks are the OBD2 port and whether you need AutoAuth access for your vehicles.
Who should choose the Thinkscan 689
Buy it if you are a mechanic or shop owner who needs bidirectional controls across full systems, more than 30 service functions and coverage of 140-plus brands without a yearly subscription.
Skip it if you only need basic engine code reading on a single personal car, or if you cannot confirm coverage for your models first. Check the VIN compatibility question with the maker before you order, and account for AutoAuth costs if your fleet includes FCA vehicles.
