What are the steps for the vehicle startup self-test? How long does the vehicle startup self-test take?

Many car owners know the importance of self-checking before starting the car. The self-checking process before starting the car is very important for the car. It can find car problems in time and prevent further damage to the car after starting the engine. Therefore, self-checking is still necessary. Let's take a look at the steps of vehicle self-checking.

What are the steps for starting a vehicle self-test?

There is no need to go through the power-on gear to start the vehicle, just ignite it directly. The reality is that there are indeed few cases where the vehicle malfunctions due to skipping the power-on gear and igniting directly, which is characterized by many people as one-button start. In fact, this understanding is wrong. Since the manufacturer has not cancelled the power-on gear for so many years, it means that it has its value. The meaning of one-button start is that you only need to press it once after the power is turned on to ignite. Of course, you can also press the button hard to skip the power-on gear to ignite in order to save trouble.

Now answer the question. If you insert the key into the car and turn the car clockwise to the first gear and stop, the on-board computer will start the battery and power up all the electrical devices in the car. Many warning symbols will also appear on the instrument panel. This is the self-check stage.

How long does it take to start the vehicle self-test?

There will be a process after the vehicle is connected to the power supply. Mainly, the vehicle computer will first detect whether there is any fault in each system. If there is no fault, the fault light will go out. If there is, the fault light will still be on after starting the engine.

Under normal circumstances, the vehicle self-check takes about 1-3 seconds. When we start the vehicle, we don't need to wait for the vehicle to complete the self-check. We can start the ignition directly. This will not affect the normal use of the vehicle. Only when the temperature is very low, we need to give the engine a warm-up time to start the vehicle at one time. In other cases, we can start the ignition directly without waiting for the self-check to complete.

Why does the vehicle start self-test?

Self-checking is actually a matter of a split second. If you follow the intuitive light display on the dashboard, it will take about 2 seconds. Although technology is advancing, many cars are now equipped with a one-button start function, but the process and function of car self-checking must exist and is a necessary safety reminder. Just like the motherboard self-checking when our computer starts, it detects whether the basic electronic equipment is normal. We may only pay attention to the normal startup and operation of the computer, but the motherboard completes the self-check while powering other hardware, just like the moment the car is powered on, the relevant sensing unit will also detect whether the connection and signal reception are normal.
