What is the reason for the FAW Toyota dashboard displaying no information?
3 Answers
FAW Toyota dashboard displays no information for the following reasons: 1. Check if there is a loose connection in the dashboard connector. In this case, data may be lost momentarily and then restored instantly. 2. The internal chip of the dashboard is damaged, causing intermittent faults, sometimes working and sometimes not. This requires professional inspection and repair at a specialized repair shop or an authorized 4S store. Below is more information about the car dashboard: 1. The car dashboard is a device that reflects the working conditions of various vehicle systems. It generally consists of a speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and electronic indicator lights. 2. The car dashboard is an important interface for information exchange between the driver and the vehicle. 3. The electronic display devices used in cars mainly include light-emitting diodes (LEDs), vacuum fluorescent displays (VFDs), and liquid crystal displays (LCDs).
I've been repairing cars for nearly twenty years and have seen many cases of no information on the dashboard. Usually, the first thing to check is a blown fuse. For FAW Toyota, the fuse box is located under the driver's seat or in the engine compartment—look for the one related to the dashboard. Insufficient battery voltage could also be the issue; a loose connection can cut off power. Secondly, the dashboard itself might be faulty, such as a broken screen, requiring replacement parts that can cost anywhere from a few hundred to a thousand yuan. Short circuits or water damage are also common culprits, especially during rainy or humid weather. Voltage fluctuations during vehicle startup can also trigger the problem. I usually advise car owners to first check the fuses and battery themselves, keeping a basic toolkit in the car. If there's no improvement, head to the 4S store immediately for a CAN bus diagnosis using a computer diagnostic tool—never attempt to dismantle it yourself to avoid worsening the issue. For prevention, regularly clean the battery terminals and connectors to prevent corrosion and oxidation, and avoid modifications like installing additional audio systems that increase electrical load.
I've been driving my Toyota Mark X for three years, and last time the dashboard suddenly went completely black, which really scared me. I checked the vehicle manual and found the dashboard fuse located near the footwell. After pulling it out, I discovered it had blown. I went to an auto parts store and spent just a few cents to buy a replacement of the same specification, and everything worked fine after installing it. Driving without being able to see the speed or fuel gauge is really dangerous, so I immediately pulled over and turned on the hazard lights. The cause might have been a loose battery terminal or excessive discharge. I make it a habit to check the battery voltage every month to prevent it from draining. For minor issues like poor switch contact, I try tightening them myself. Long-term neglect can easily lead to bigger faults, so whenever I encounter any problem, I take it to a professional shop to check the wiring. It takes time, but it gives me peace of mind.
