Check your car's coverage before you buy
Compatibility is your first step with the ThinkScan 689. The scanner covers 140+ car brands and 10,000+ vehicles, but THINKCAR's own note on ECU coding says available functions change with model and year.
Autoauth for FCA SGW is listed as a supported feature, so if you drive a Stellantis vehicle with a secure gateway, this tool is designed for that scenario.
We'd consider this a strong match for a home mechanic who wants one wired device to read all available systems, from ECM to airbag, rather than a basic code reader that only touches the engine.

What it will not do
This scanner reads and resets systems, but it does not fix mechanical faults. A code for a failing sensor still points you toward the repair, not around it.
The 34 reset functions cover common jobs like oil light, EPB, BMS and injector coding. Whether a specific reset applies to your car depends on the model and year, so check that list before purchase.
It also will not replace a shop for safety-critical work such as airbag deployment or brake bleeding unless you already understand the procedure.
Reset functions are supported per vehicle. Confirm yours before you rely on one.
Coded functions vary by model and year, so verify the feature you want.
The price and what the comparison means

At $392.99, this unit is $53.78 below the typical price over the last 90 days of $446.77, which is about 12% off. That figure is a recent average, not a typical price over the last 90 days set by a retailer.
The price sits in the range of a serious diagnostic tablet, so it is worth comparing what you get for the money. You get full-system diagnosis, 34 reset functions and bi-directional controls, none of which require a subscription per the lifetime free wording.
Power and connection details to confirm
The scanner connects through the OBD interface, so check that your vehicle has a standard OBD-II port. This is a wired tool, which means no Bluetooth pairing or battery to manage in the garage.
The listed hardware includes 4GB RAM and 64GB storage, and the tool supports CANFD and DoIP protocols. If your car uses one of those newer protocols, confirm that support in the vehicle list.
THINKCAR offers in-app chat and email support around the clock, which matters if you are setting up coding for the first time.
Who should choose this scanner
Choose the ThinkScan 689 if you work on multiple vehicles and want full-system access plus bi-directional tests without paying per-reset fees. The lifetime free reset functions are the standout for someone who does their own maintenance.
Skip it if you only need to read engine codes on a single older car, since a basic reader costs far less. Skip it also if your vehicle is not confirmed in the coverage list, because no discount makes an incompatible scanner useful.
