*Accelerator pedal can’t be pressed during the basic setting process

3，Basic setting method and process:

1, Turn the key to ON (power mode, no start), enter engine system

2, Connect to X-431 decoder

3, Check fault code→ Clear fault code 

4, Choose relevant vehicle while choose “ common mode”-“fast dataflow diagnostic mode”-“engine system”, 

choose “System basic adjustment function” and input adjustment group number: different vehicle, different channel number.

Match Manually

Two different methods to initialize for different vehicles 

The first method : Turn the key to ON ( power mode, no start), press the accelerator to the bottom after 20 seconds,
