THINKCAR Thinkdiag 2 Diagnostic Scanner

Thinkdiag vs Thinkdiag 2
The most significant difference between thinkdiag and thinkdiag2 is CAN FD protocols. Thinkdiag2 has a built-in CAN FD protocol. It is the only product in this price range that is compatible with CAN-FD protocol and supports the latest GM vehicles manufactured after 2020. Thinkdiag 2 adopts advanced CRC algorithms to accommodate more data from 8 to 64 bytes in the CAN frame, which runs faster than other products, and reduces the risk of undetected errors to enhance the user experience significantly.

ThinkDiag2 Has 15+ Poular Maintenance Reset Function

Oil Light Reset: This allows you to recalculate the engine oil life system after an oil change.
TPMS Reset: When the car tire pressure fault light is on, after carrying out maintenance, you need to reset the tire pressure through the tire pressure reset function to extinguish the tire pressure fault light.
Brake pad reset: When the brake pads and brake pad wear sensing line are replaced, the brake pad indicator lights up, after the brake pad sensor line short circuit is repaired, or after the servo motor is replaced, the reset needs to be done.
SAS Calibration: Calibrate the steering angle sensor and clear the fault memory.
Battery Reset: It is to use Thinkdiag2 to perform a reset process on the monitoring unit of the car battery, clear the original fault information about the battery being low, make it match again, and let the monitoring unit monitor with the relevant information of the existing battery as the standard.
ABS Bleeding: When the ABS system contains air, the brake system needs to be exhausted through the ABS exhaust function to restore the ABS system braking sensitivity. The ABS bleed function is required when replacing the ABS computer, ABS pump, brake master pump, brake sub-pump, brake lines, and brake fluid.
ETS Learning: Initializes the throttle actuator to restore the "learning" values stored on the ECU to their default state.
DPF regeneration: Generally, D-P-F regeneration matching is required when the exhaust back pressure sensor is replaced, the particulate trap is removed or replaced, the fuel additive nozzle is removed or replaced, the catalytic oxidizer is removed or replaced, the DPF regeneration fault light is illuminated and matched after repair, and the D-P-F regeneration control module is repaired and replaced, mainly to remove the trap performance by using combustion oxidation on a regular basis Always maintain the best stability.
Injector Coding: usually in the replacement of ECU, the injector nozzle, is required to confirm the code of each cylinder nozzle or re-code. So that the cylinder can better identify each cylinder nozzle, and more accurate control or correction of the amount of fuel injection of each cylinder.
Sunroof initialization: This function can set the sunroof locking off, closing when it rains, memory function of sliding/tilting sunroof, outside temperature threshold, etc.
EGR Adaption: This function can be used for self-learning after E-G-R (Exhaust Gas Recirculation) valve cleaning or replacement
Suspension Matching: When replacing the body height sensor in the air suspension system, after the control module or when the car is leveled incorrectly, this function needs to be performed to adjust the body height sensor for level calibration.
Transmission Learning: When the transmission is disassembled or repaired (after the battery is disconnected in some car models), it will lead to shift delay or shock problem, then this function needs to be performed to make the transmission compensate automatically according to the driving conditions in order to achieve a more comfortable and ideal shift quality.

ECU Coding

The ECU coding function is used to reflash the vehicle
control module, which allows you to match repaired or replaced components to the ECU. It can activate the
hidden functions for VW, for AUDI, for BENZ, and for
BMW models.
If you want to confirm whether your model can perform
this function, please provide the VIN number or specific vehicle information (year of manufacture/specific model/country of manufacture) and we will confirm for you.
Active Test

The advantage of Thinkdiag2 is that it supports full
bi-directional control capability to send commands
to the vehicle's systems/components to verify system inputs/outputs without using the vehicle controller.
like Shutter Grill Relay Test, Low-Pressure EGR Actuator Test, High-Pressure EGR Actuator Test, Intake Pressure Control Valve Actuator Test, Low-Pressure EGR System
Test, Low-Pressure EGR Differential Pressure Sensor Test, 2 stages turbocharger boost test, VTEC low V/T check, Compression Test, IMT (IMRC) test, VTEC Test, VTEC(VCM) Test.
One-Touch AutoVIN Technology

AutoVIN function supports Thinkdiag2 to automatically identify most car models, year of manufacture, and VIN
codes. You can enter the corresponding menu
and perform a one-click full vehicle scan and a system-wide vehicle health report will be automatically generated later which the report
can be shared.
Add CAN-FD protocol
