What the 689BT can do for your garage
This is a workshop-class diagnostic tablet, not a pocket code reader. The thinkcar 689BT handles full-system diagnostics across major vehicle systems such as engine, transmission, ABS, SAS and TPMS, so you can pull faults from the whole car instead of one module.
It also runs bidirectional active tests, letting you command an actuator, injector, relay or cooling fan and watch whether the part responds. ECU coding covers module matching and hidden feature activation. We'd consider this a sensible buy for someone already doing component-level work at home or in a small shop.

What it will not do
Bidirectional control and module coding vary by make and model, so this tool cannot confirm that every function works on every vehicle. It reads and clears codes across the systems it supports rather than repairing a fault by itself. Wi-Fi is needed for the software update that unlocks the AI-assisted diagnostic guidance.
Bidirectional control and ECU coding are not universal across all makes and model years.

The tool reports faults and runs supported tests, it does not repair them.

At $509.99, the 689BT sits $43.26 below its typical price over the last 90 days of $553.25, which works out to 8 percent off. That is a modest saving on a capable bidirectional platform rather than a dramatic drop, so the value case rests on the feature set rather than the discount.
What to check before you buy
Confirm that your specific makes and model years are covered for bidirectional tests and ECU coding, since these features are not universal. Check that the 8-inch touchscreen, quad-core processor and Android 10 interface fit your working setup, and that you have a stable Wi-Fi signal for the software updates and the AI-assisted guidance.
Who should choose this scanner
Choose the 689BT if you want one tablet that covers full-system reads, active component testing, ECU coding and 34-plus reset and maintenance jobs without paying dealership rates. Skip it if you mainly need basic code reading, since a simpler reader costs far less. Skip it too if your vehicles fall outside the supported coverage for bidirectional control.
