thinkcarBidirectional Scan Tool, THINKSCAN 689BT All System Automotive Diagnostic Tool, Bi Directional OBD2 Scanner with ECU Coding, 34 Services, FCA Autoauth, CANFD and DoIP, Wireless Update

This was fairly expensive, but worth every dollar! Touch screen and bluetooth, no need for wires or being in vehicle to use. The scanner is a great quality, very easy to use and understand. Extremely functional and can read and control many many different systems in the vehicles. Overall very happy with this purchase, even with the cost. Will always come in handy

Worked flawlessly to manually program a Ford ABS module. Very easy to setup and update fast with no problems. For the money this unit is superior to more expensive scanners.

Great scanner, saved, me $300 not having to go to dealer to handle Low def fluid reset. Amazing what this can do. Great product.

It's not a dealership grade laptop, however it is a very quality product especially for its price and free lifetime updates. As soon as mine arrived i put it straight to work. Easy to use and understand offers most all features to diagnose whatever issues you may encounter. No complaints highly recommend 👍

The ThinkCar bidirectional scan tool is a major upgrade over basic OBD2 devices. Equipped with a Bluetooth OBD2 adapter, it offers wireless diagnostics—no cables cluttering your dashboard. Research shows the ThinkScan 689BT model supports OE-level full-system diagnostics, bidirectional active tests, ECU coding, and 34+ maintenance services, with free lifetime updates and no subscription fees.In my experience, setup was smooth—just pair the dongle to the Android-based tablet. The interface is responsive, and connecting vehicle modules (ABS, airbags, transmission, etc.) took only seconds. The build quality feels robust, suitable for shop or field use. For the price, it’s a bit of an investment, but if you’re a mobile technician, shop owner, or experienced DIYer, it delivers the depth and reliability of higher-end lab tools.Q&A:Q: Does this support bidirectional (active) tests and ECU coding like premium diagnostic tools?A: Yes, models like the ThinkScan 689BT support bidirectional control, including active tests (e.g., pump, injector, fan, window), plus ECU coding and 34+ maintenance resets—all at no extra cost.Q: Is the Bluetooth connection stable and easy to use?A: Very stable. The Bluetooth OBD2 dongle connects quickly, and diagnostics run smoothly—no wires to manage.Q: Are updates free and does it require a subscription?A: Yes, ThinkCar offers lifetime free updates, with no subscription fees. The tool keeps getting new car coverage and features

This scanner arrived in a condition that completely undermines trust: it was already registered to another account. That alone would merit a refund, but it turns out the registration issue was just the first of many failures. Advertised as a professional-level bidirectional scan tool with wireless updates and advanced features like ECU coding, CANFD, DoIP, and AutoAuth for FCA vehicles, the THINKSCAN 689BT couldn't even get the basics right.Out of the box, I expected auto-search to scan and identify the vehicle system with minimal input. What I got instead was an error-prone guessing game that forced me to manually enter basic vehicle information- something even cheap generic OBDII tools do automatically and correctly. I spent more time navigating failed connections and incomplete module detection than diagnosing anything useful. It felt like this tool had the guts of a budget scanner buried under a flashy touchscreen and inflated claims.The user interface feels clunky and outdated. Menus are inconsistent, scanning speed is painfully slow, and the bidirectional functions are hit-or-miss at best. Many of the functions I tried either failed to execute or required multiple retries just to connect. It promises full system diagnostics, but several ECUs couldn’t even be accessed on vehicles where I know communication is possible. I tested it on a late model FCA vehicle and a mid-range GM model, both of which required multiple retries just to consistently pull the same DTCs I can pull from my 2 other scanners. We are not even talking advanced advanced diagnostic scans. Just basic codes.Wireless updates? The process froze during the initial update and device restarted. I eventually got it updated, but the first experience was anything but confidence-inspiring.When I dug deeper into reviews across seller platforms, I found a disturbing pattern: many buyers also received pre-registered devices. Others mentioned having to contact the company to clear account lockouts. That means THINKCAR is either repackaging returns as new or has an inventory control problem that allows used units to be sold again. Either way, that's unacceptable.The worst part is that none of this is priced like a budget tool. This unit sits in the mid-to-upper tier range and for that, it has to deliver. It didn't. The combination of misleading sales practices, half-baked firmware, and a basic failure to deliver even entry-level performance is a deal-breaker.Support is a condescending joke. They ignore all questions that require any knowledge of how to use the product and pick and choose anything else based on whatever sounds the most condescending. I absolutely abhor this product and their support.Pros:Device physically appears sturdyOn paper, feature list seems impressiveCons:Device arrived already registered to another userAuto vehicle scan failed many subsystem and package detectionsInterface is confusing and poorly optimizedBidirectional functions often fail to connect or perform their expected functionBasic DTC reading is unreliable across common vehiclesWireless update can fail providing 0 user feedback just a reboot and retryCustomer support response times are atrociousMarketing claims do not reflect real-world performanceOther buyers have reported the same registration issueHot Take:What THINKCAR delivered here is a bloated tool that pretends to be high-end while failing at even the basics. Getting a used device labeled as new is already grounds for distrust, but when you add in failed scans, broken auto-detection, and buggy software, and the absolute worst customer support, the THINKSCAN 689BT becomes an overpriced paperweight. The best thing this scanner did was convince me to return it and never look back.

This scanner’s gotta be one of the best scanners I’ve used for the money I paid. This super fast scan tool simplifies diagnosis with plenty of special functions and actuations.

What is this? （The 689BT only provides a login and purchase portal, and users are required to register for an FCA account and pay a membership fee in order to perform the relevant automotive diagnostics) this is on their description. No one is talking about this. how much is the fee? is it a one time fee? or every year?
