The card slot of the car is broken, what should we do to solve it?

Is the car bayonet broken? We should solve this problem. When we encounter problems with our car, we should not panic. Read the car editor's article to tell you how to deal with it calmly.

1. Check whether the card has poor contact. If the lock is not tight, most of the cigarette lighter's power supply will not break. If not used for a long time, there will be poor contact. Insert the plug into the end and turn it over.

2. Open the fuse box, see where the cigarette lighter fuse is, and then unplug it. You have a spare fuse in the fuse box and replace it.

3. Try pressing the cigarette lighter of other cars and see if it pops up when it is red. If it rebounds, it means that the original cigarette lighter is broken, such as the heating wire is short.

4. It does not need to be just a fuse, it can always be plugged into the navigation or external appliances. When you hold the cigarette butt slightly on the lighter, you will burn the fuse if you are careful to ground it.

When the cigarette lighter cannot be used, just open the power cover at the foot and replace the fuse.

OBD, also known as: on-board automatic diagnosis system, can check the working condition of functional modules such as the car's engine electronic control system while the car is driving. With the help of the connection between the car OBD interface and the computer, car data and car faults can be viewed in real time, which provides convenience for car maintenance, car-related function development, and car equipment modification.

However, the OBD interface cannot be directly connected to the computer, and must pass through a "Gateway" device. In order to interconnect, in view of this, here we rely on the Guangcheng Technology's USBCAN-OBD device. Next, let’s talk to our friends about how to use the car’s OBD interface and USBCAN-OBD function. Find the car OBD interface, insert the 16-pin OBD-II interface of the Guangcheng USBCAN-OBD device into the car interface, and connect the other end to the USB terminal of the computer. The USBCAN-OBD interface card and PC are directly connected to the USB interface of the PC through the USB cable of the device itself. The USB interface of the PC provides +5V power for the USBCAN-OBD interface card, using direct bus power supply. After the driver and software are installed normally, plug the device into the USB interface of the PC and you can find the new USBCAN device in the PC device manager. The driver is called "Gas Chromatography-Technology Ultrasonic Scanning Equipment". If there is no yellow exclamation mark or question mark, it means that the device driver is normal and the USBCAN device is connected to the PC normally. After the USBCAN-OBD interface card is powered on, the SYS light lights up in red, indicating that the device power supply is normal and in the initialization state; when the computer recognizes the USBCAN device, it will automatically load its driver, and the indicator light will turn green after loading. After the USB interface is connected normally and the software turns on the device, the SYS light flashes slowly. When there is data transmission on the USB bus, the USB signal indicator SYS flashes quickly.
