Why doesn't the central control panel of Corolla display vehicle information?

The Pacific car network is caused by poor line contact. Check whether the anode and cathode of the battery are frosted, and clean the battery terminals. If the wiring is not in good contact, you can check the wiring harness of the central control panel, plug in the wiring harness connector of the central control panel, blow it with a hair dryer, and then restart the system.

It may be that the display is broken and needs to be replaced, or it may be a system problem. The specific solution is:

1, the screen fault can be caused by thin hard objects such as paper clips or toothpicks. Insert the first hole (reset key) of DVD to restore the machine to the initial state;

2. Removing the battery fuse post of the car has the same meaning as the reset mentioned above. Note: Generally, you can remove the battery fuse for 30 seconds and then put it back;

3. Check whether your DVD navigation has returned to normal through the above two methods. If it's not normal, it's usually that the cable of your touch screen or the contact in the screen is broken. When changing a DVD, first remove the touch screen of DVD navigation to see what model it is before buying it.

Most of them are caused by poor line contact. Check whether the anode and cathode of the battery are frosted, and clean the battery terminals.

It may be a poor connection. You can check the harness of the central control panel, plug in the harness connector of the central control panel, blow it with a hair dryer, and then restart the system.
