Diagnostic Four Systems Instantly
THINKCAR 641 Professional: Your Comprehensive Vehicle Diagnostics Solution
The THINKCAR 641 diagnostic tool is an advanced OBD2 scanner engineered for professional-grade diagnostics across a vehicle’s most critical systems. With robust 2GB RAM and 32GB of internal storage, it delivers the speed and capacity needed for in-depth analysis, helping technicians and informed DIYers accurately identify issues, perform resets, and ensure vehicle safety and performance.
Full-Featured Engine Diagnostics
Go beyond basic code reading. The THINKCAR 641 OBD2 scan tool retrieves and erases engine DTCs, displays real-time live data streams for precise troubleshooting, and resets the Check Engine Light. It empowers you to diagnose a wide range of engine performance issues—from sensor failures (like O2 sensors) and ignition problems (aged spark plugs) to more complex concerns involving fuel delivery, cooling system efficiency (coolant leaks, radiator blockages), and internal mechanical health (oil pump failure, lubrication issues, detonation). This proactive approach helps prevent minor faults from escalating into major engine repairs.
Integrated ABS & Brake System Analysis
Safety systems demand precise tools. THINKCAR 641 automotive scanner diagnostic tool provides dedicated functionality for the Anti-lock Braking System (ABS). It actively communicates with the ABS module to pull specific fault codes that illuminate the dashboard warning light, guiding you to common culprits such as faulty wheel speed sensors, issues with the hydraulic system (low brake fluid), or electrical faults (blown fuses). After repairs are completed, the tool allows you to clear the codes and extinguish the ABS light, confirming the system is fully operational.
SRS (Airbag) System Safety Verification
Ensure the vital Supplemental Restraint System (SRS) is ready to protect. The THINKCAR 641 vehicle scanner diagnostic tool safely accesses the airbag control module to read existing fault codes, which can indicate problems with sensors, clock springs, or the module itself. By clearing these codes after verified repair, you can turn off the persistent airbag warning light, restoring confidence in this life-saving system and ensuring it functions as designed in the event of a collision.
Transmission System Performance Monitoring
Catch transmission issues before they lead to costly rebuilds. This car scanner diagnostic tool enables diagnostics on the transmission control system, allowing you to read transmission-specific DTCs and view key live data parameters (like shift solenoid activity, fluid temperature, and gear ratio). This insight helps verify that the transmission is operating in sync with engine load and vehicle speed. Resetting the transmission warning light after addressing faults is a straightforward process, helping to maintain optimal drivetrain performance.
Why Choose THINKCAR 641?
The THINKCAR 641 auto scan tool consolidates professional diagnostics for the Engine, ABS, SRS, and Transmission into a single, powerful device. It’s built for accuracy, depth, and efficiency, translating complex vehicle data into actionable insights. Whether for professional workshop use or the serious enthusiast, it’s a smart investment in comprehensive vehicle care and maintenance.

10 Full Upgraded Maintenance Reset Functions
OIL RESET:The maintenance light reset function allows you to turn off the maintenance light when the engine oil maintenance light illuminates, indicating that the vehicle needs maintenance. After maintenance, you must reset the mileage or driving time to zero. This will activate the new maintenance cycle.
ABS BLEEDING:ABS (Anti-lock Braking System) Bleeding. When the ABS system contains air, it needs to be bled to restore its braking sensitivity.Without ABS, emergency braking typically causes the tires to lock up. Because the tires slide against the ground after locking, the braking distance increases. If the front wheels lock up, the car loses lateral steering force and is prone to veering; if the rear wheels lock up, the rear wheels lose lateral traction and are prone to skidding.ABS ensures the vehicle’s braking and directional stability, preventing skidding and veering.ABS controls wheel lockup by regulating brake fluid pressure. Its operation is essentially a cycle of lockup – release – lockup – release, keeping the vehicle in a state of intermittent rolling at the point of near-lockup.
AIRBAG RESET:This function can reset airbag data and clear the airbag collision fault indicator light. When a vehicle is involved in a collision and the airbags deploy, corresponding fault codes will appear, and the airbag indicator light will illuminate. These fault codes cannot be cleared. Since the data in the airbag computer is disposable, it is normally required that all parts be replaced with new ones. However, by executing this function, the airbag computer data can be restored, fault codes can be cleared, the airbag indicator light will turn off, and the airbag computer can continue to be used.
BATTERY MATCHING:Battery matching involves using automotive diagnostic equipment to reset the car battery’s monitoring unit, clearing existing fault information related to low battery charge and rematching it to the current battery information.A car battery normally operates at a voltage above 12V. When the engine starts, the alternator charges the battery, raising the voltage to 13.8-14.4V. Many cars have voltage monitoring functions; observing the voltage change before and after starting can help determine if the battery is good or bad. If the voltage is below 12V before starting or below 13V after starting, the battery needs to be checked and replaced.
BRAKE-PAD RESET:When brake pads reach a certain thickness, they will wear down the brake pad sensor wires. At this point, the sensor wires will send a signal to the vehicle’s computer, prompting for brake pad replacement. After replacing the brake pads, a brake pad reset is required; otherwise, the warning light will continue to illuminate.
DPF RENERERATION:The DPF regeneration function primarily utilizes periodic combustion oxidation (such as high-temperature combustion, fuel additives, or catalysts to lower the ignition point of particulate matter) to remove particulate matter from the filter, ensuring optimal and stable filter performance.DPF (Diesel Particulate Filter), also known as a diesel particulate regenerator, is a device that reduces particulate matter (PM) emissions from exhaust gases. During operation, particulate matter accumulates inside the filter. When it reaches a certain level, it can lead to a decline in engine power and fuel economy. Therefore, it is essential to remove the deposited particulate matter promptly to ensure the DPF continues to function properly; this is what is known as DPF regeneration.
ELECTRONICS THRITTLE ADAPTION:Throttle body matching involves using a car decoder to initialize the throttle actuator, returning the ECU’s learned values to their initial state. This allows for more accurate control and adjustment of the throttle body (or idle air control valve) to regulate the intake air volume.
INJECTOR CODING:To more accurately control or correct the fuel injection quantity in each cylinder, the actual coding of the fuel injectors must be written into the ECU or the coding stored in the ECU must be rewritten to correspond to the coding of each cylinder’s injector.A car fuel injector is a simple solenoid valve. When the solenoid coil is energized, it generates suction, lifting the needle valve and opening the injection orifice. Fuel is then sprayed at high speed through the annular gap between the needle valve head and the injection orifice, forming a mist, which facilitates complete combustion of the fuel.Typically, after replacing the ECU and fuel injectors, it is necessary to verify or recode the coding of each cylinder’s injectors so that the cylinders can better identify the injectors and precisely control fuel injection.
Steering angle reset: Steering angle reset refers to finding the relative zero point position for the vehicle to maintain straight-line driving. Using this position as a reference, the ECU can calculate the precise angles for left and right turns. After removing or replacing steering-related components, the steering angle learning function needs to be performed. Some vehicle models require the use of specialized diagnostic tools to learn and set the steering angle.
TMPS RESET:When the tire pressure warning light illuminates, after maintenance, the tire pressure needs to be reset using the tire pressure reset function to turn off the warning light.Tire pressure reset is a tire pressure monitoring operation. It typically triggers an alarm when tire pressure is abnormal, such as when tire pressure is too low or there is a leak, after replacing or adding a tire pressure monitoring system, after tire replacement, when the tire pressure sensor is damaged, or when tires are rotated in vehicles with tire pressure monitoring systems. Tire pressure reset is necessary after vehicle maintenance.

Tons of features, but UI can be difficult to understand.
This OBD2 scanner is an awesome tool for an independent shop or backyard mechanic. It is also a great backup scanner for a larger shop. It has a wireless module which connects to the car, and then the data can be read sitting anywhere in the vehicle. This is very useful for diagnosing complex issues where a driver needs to be paying attention while a mechanic examines live data.I really liked the easy to read touch-screen display. It makes things so much easier to use than mashing buttons like on my older scanner. The one downside is that it did not come with any kind of screen protection, so I recommend grabbing a screen protector. The shop environment is filled with dust, oil, and other contaminants, so I feel like having some kind of protection is paramount. Another small issue is that there is no obvious way to attach the wireless scanner to the screen so they don’t get lost when not in use. No bag is included. I ended up putting a bit of hook and loop tape on mine to keep them organized.The screen and computer itself are the real start of the show. Having a big screen makes it easy to graph multiple metrics in real time. The computer is quite powerful. It can record data, play it back, e-mail reports to customers or service centers, organize data, and a bunch more. It has a ton of capability for its price. There are obviously certain functions it will not be able to do, so for deeper mechanical or security work this scanner may not be enough.My one real complaint with this scanner is the software user interface (UI). I found it confusing to navigate and anticipate how it would behave. It kept putting me in odd loops I couldn’t figure out how to get past. Some of the terminology used is very unclear. There is not a good manual available, and there doesn’t seem to be a good on-line help system. With enough patience, I think I can master this. It will just take a lot more work than other scanners that are easier to use.Overall this is a very good value OBD2 scanner with some advanced features. Most home or backyard mechanics are unlikely to ever use some of the bigger capabilities like report generation and multi-function recording. I personally would rather have these features than not. I do recommend using the scanner quite a bit before relying on it for anything important as the software will take some practice to use well.
