What your vehicle needs to support
We'd consider the THINKCAR THINKSCAN 689BT a reasonable pick if you work across several makes and want one tool that reads all available systems rather than engine codes alone. It covers 140 worldwide car brands, including passenger cars, 12v pickups, hybrids and SUVs, and it reads systems such as Engine, Transmission, Brake, TPMS, Battery and SAS.
The coverage you actually get depends on your model and year, so confirm your car appears in the current compatibility list before you buy. Two protocols matter here. CAN FD and DoIP communication is supported, and 2018 and newer FCA vehicles rely on AutoAuth, which the 689BT reaches through a login and purchase portal only. You still register an FCA account and pay its membership fee separately to run those diagnostics.
Coding is the other variable. ECU coding, power balance, hidden function flashing, adaptive data resets and component matching are all listed, but the available options differ by model and year. Our advice is to check your specific vehicle against the service list rather than assume every function applies.

What it will not do
Bidirectional control means the tool can command subsystems and components for active tests, so it helps you verify a circuit or component response instead of only reading a stored code.
That is a diagnostic function, not a repair. The 689BT does not fix a fault, and it does not make a vehicle safe to drive after a fault appears.
It reads and tests systems; it does not repair faults or certify a vehicle as safe to drive.
Active tests require the tool to command components, so confirm the specific test exists for your model.

What to confirm before ordering
Plan for WiFi to reach the software updates and unlock the Tyler AI Agent feature. Once updated, the tool walks you through diagnostic steps, shows illustrated references and suggests parts that may need replacing, with a tap that jumps to Amazon to check parts pricing.
The package includes gateway accessories, so check what shipped in your box before ordering extras. Because the listing notes that customer returns sometimes reach buyers as used units, inspect what arrives and use Amazon's exchange path or messaging if something looks off.
If your diagnostic routine depends on a specific active test, confirm that test is available for your model before purchase. Examples listed include EVAP, fuel trim reset, injector buzz and window, mirror or door lock tests, reached through Diagnose, Car Model, System, then Active Test.
Who should choose this scanner
Choose the 689BT if you maintain multiple brands or run a small shop and want bidirectional control, 34 service functions and all-system diagnostics in one wireless unit. The lifetime WiFi updates and 28 supported languages suit a working garage.
Skip it if your work centers on one vehicle whose coding functions the tool does not cover, or if you need FCA diagnostics without the separate membership cost. Check the active test list for your daily driver, then confirm your model and year appear in the compatibility chart.
