4 Systems Diagnostic Tool

For Engine System:
Easily determine the cause of the Engine System, and turn off the warning light. Guides you to find out problems in engine, check its real-time operating status, and turn off warning light for making sure engine work properly and safely.

For Auto Transmission System（ATS):
Read and clear codes and view live data in transmission systems, keeps the transmission systems output optimally adapted to the speed and load. Retrieve the error information from Automatic Transmission (AT) which is a type of motor vehicle transmission that can automatically change gear ratios as the vehicle moves, freeing the driver from having to shift gears manually.

For Diagnose ABS (Anti-lock Braking System):
Read and clear DTCs data flow in the ABS. Performs various bi-directional tests to check the operating conditions of Anti-lock Braking System, and turn off the warning light. It retrieves ABS codes to tell you where the problem is with a visual inspection of all brake components.

For SRS (Airbag) :
Read and clear fault code in SRS (Airbag) and turn off warning light of airbag for making sure engine work properly and safely. This diagnostic tool allows you to read codes, clear codes, and read live data in Supplementary Restraint System (airbag) to ensure it works fine.

7+ Maintenance Service Functions

ABS Bleeding：ABS brake bleeding to get a firm brake pad after air exhaustion. 

Battery Matching：Allows the scan tool to evaluate the battery charge state, monitor the close-circuit current, register the battery replacement, and activate the rest state of the vehicle. 

Brake Reset：Helps maintain the electronic braking system safely and effectively, deactivating and activating the brake control system, assisting with brake fluid control, opening and closing brake pads, and setting brakes after disc or pad replacement, etc. 

Electric Throttle Relearn：The throttle body is a tube containing a pivoting flat(butterfly) that is used to control the amount of air entering an engine. In an electronically fuel injected car , a throttle position sensor and air flow sensor communicate with the computer , which supplies the corresponding amount of fuel needed at the injectors. It must need re-learning throttle sensor position after clearing or repair. 

Gear Learning: resets the transmission for smoother shifting and optimal capability.

Oil Maintenance Reset：Allows you to perform reset for the Engine Oil Life system, which calculates an optimal oil life change interval depend on the vehicle driving conditions and climate. 

Steering Angle Reset：Helps clear the fault steering angle sensor memories and plays an important role in the steering angle sensor calibration.
