Product Overview

I recently had the opportunity to review Thinkcars All System Bidirectional Control OBD2 Diagnostic Scanner, and I must say that I am impressed. This scanner is a great option for car owners, DIYers, and small repair shops who want to diagnose their vehicle quickly and accurately.

This scanner supports full system diagnosis and can provide information on all systems such as ECM, ABS, SRS, TCM, EPB, TPMS, SAS, A/C, BMS etc. It has a separate menu of 15 common special functions such as oil reset, EPB reset, DPF regeneration, SAS calibration etc. It can also be used to match replacement components to the ECU. In addition to these features it provides ECU CODING which allows you to match replacement components to the ECU.

The scanner also supports bi directional control diagnostic tests which can be used to send commands to the system/component in order to test its operating status without using the vehicle controls. This makes it easier and faster to identify the cause of any fault. It also supports the CAN FD protocol which is compatible with the latest GM vehicles manufactured after 2020 and can unlock FCA vehicle SGW module on Chrysler, Dodge, Jeep Alfa Romeo and Fiat vehicles manufactured after 2019.

The scanner comes with an Auto VIN function which can help car owners/repair stores automatically identify the year of manufacture, model and VIN of most models. It also has a Health Report feature which will automatically generate a detailed vehicle health report after diagnosis. Reports and diagnostic records can be viewed in the REPORT and HISTORY menu and reports can be shared or printed out if needed. Additionally it supports Bluetooth 5.0 BLE dual mode for stable transmission and faster processing speeds as well as a 23 inch long DB15 three row OBDII 16 pin diagnostic cable for faster communication.

Finally Thinkdiag2 OBD2 Diagnostic Scanner comes with a cost effective price tag making it an ideal choice for car owners who want a reliable diagnostics tool at an affordable price point. It is also easy to use thanks to its simple user interface and intuitive controls so even those who are not very tech savvy should have no problems operating this device. Overall I highly recommend this product if you are looking for an all in one diagnostics tool that wont break your budget but still offers great performance!
