On-board Computers Should Also Be Careful To Wait

While enjoying the power of the on-board computer, do not ignore its maintenance common sense during daily use. Especially for those owners who have DIY on-board computers, this maintenance awareness should be strengthened.
When servicing the vehicle, once the ignition switch is turned on, whether the engine is running or not, do not disconnect any wire. Because the self-inductance of the coil generates a high instantaneous voltage at the moment of disconnecting the wire, it is easy to damage the computer and the sensor. At the same time, high-impedance digital test tables should be used as much as possible in testing, and it is forbidden to use test lamps to test any electrical devices connected to the computer, so as not to damage the computer and sensors.
In addition, the decoration of the items in the car and the different environments of the vehicle will also have a certain impact on the on-board computer. For example, objects with strong magnetic fields should not be close to the computer, otherwise their components or lines will be damaged, such as speakers, recorders, heaters, etc. should be installed as far away from the computer as possible. When the environment is relatively humid, if the computer is affected by moisture, the circuits and components are easily damaged. Therefore, if the car owner washes the vehicle, he should be especially careful to avoid water entering the computer. If you find that there is a leak in the installation computer, you should repair it as soon as possible.
