1With this diagnostic tool, you can quickly determine the cause of the engine system, and then turn off the warning light. It also retrieves the current code, permanent code and pending code in the vehicle engine system. Retrieve Vin information and more information (Up to supporting 108 systems). 2When you see the Abs (anti-lock braking system) indicator light is on, you know it is serious. A diagnostic instrument can help. Simply plug it into the 16-pin port (usually under the steering wheel) to determine what went wrong. You can determine the cause of the error, insufficient brake fluid, blown fuse, or abnormal signal from the wheel sensor. 3When the Srs (Safety Restraint System) indicator lights up, it means that the Srs control unit has found a problem in the system. You can use this tool to check whether the Srs system is faulty and repair it. It is very important for Srs to always maintain normal operation. 4If you notice the following conditions, gearbox slipping, heavy gear shifting, delayed engagement, oil leaks or gearbox warnings, you may need to service your car. You can use the diagnostic tool to perform a series of diagnosis and find out the problem areas that need repair. 5The steering angle sensor (Sas) is an important part of the Esc system, which can measure the position angle of the steering wheel and the turning rate. Sas is very important for the safety of drivers and passengers. When the Sas indicator light is on, you can use this diagnostic tool to read the error code. After solving the problem, you can use the diagnostic tool to recalibrate and clear the code. 6The electronic stability program (also called electronic stability control system) can improve the stability of the vehicle by detecting and reducing the loss of traction (skidding). When Esp detects the loss of steering control, please check the Esp indicator and get a code read before performing any operation. It can help you minimize the potential loss of money and life.
