1. Press the power switch to power on the training box. At this time, the motor drives the analog wheel to run at low speed, which is equivalent to the idle state of the fuel car.
2. Gradually press down the accelerator pedal. At this time, the speed of the motor is gradually increased. Observe the values ​​of the two voltmeters corresponding to the accelerator pedal position sensor and find that the value gradually increases.
3. Gradually release the brake pedal, the voltage value corresponding to the two position sensors is gradually smaller.
4. Observe the change of the speedometer when manipulating the accelerator pedal above.
5. Set the fault to the 6 lines of the accelerator pedal position sensor respectively, and find that any one of them is affected, and one of the two accelerator pedal position sensors must be affected, which is reflected in the corresponding accelerator pedal position sensor voltmeter.
6. When accelerating to a certain speed or starting creep state, press the brake pedal and find that the speed will drop significantly until it reaches 0.
7. While the brake pedal is depressed, the left and right brake lights and the high brake lights are illuminated at the same time to warn the rear vehicle.
8. The brake switch uses the normally open contact to control the brake indicator. When there is no brake, the brake indicator and the power supply are in an open state, and the brake is turned on.
9.Because the brake pedal and the accelerator pedal and the brake switch are both real objects, if the physical connector in the training box is disconnected and extended to the corresponding physical object of the original car, the original can be completely realized. Control and detection of this part of the car and setting up faults.

1. Brake pedal，acceleration pedal
2. Brake switch, power switch
3. 4 DC voltmeter
