THINKCAR Bidirectional 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

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

Scanner is super easy to navigate, setup, and update. The lifetime updates option is a very attractive selling point.

Work as described. Recommended!!!

I have try it few times and is okay. it is worth to get it as it has quite few options and plus big screen.Wished that they will add topology to it and also the key program secret pin if i want to program my own key fob on my cars. Still testing so the rating my go up or come down. I am working with a fleet of up to 80 cars,trucks, etc.

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the guts of a budget scanner buried under a flashy touchscreen and inflated claims.The user interface feels clunky and outdated.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.

My husband really loves this tool. He’s into car sales so he takes it with him to the auctions. The more he uses it and understands how to use the more he loves it.We had recently had a tune up on our truck. Our truck has 16 spark lugs. Well the mechanic forgot to hook one in so it was misfiring when reversing. He hooked this up and the machine told him exactly which spark plug was causing the misfire. The guys hooked it in and all is well now.

Muy bueno

Great for the price. It's really a great deal.
