Why does the Tiida's collision avoidance system light flash?
3 Answers
Tiida's collision avoidance system light flashing is to remind the owner that there is an obstacle in front of the car, and it is necessary to pay attention to the speed not being too fast to avoid collision. The collision warning system can automatically detect the distance of obstacles ahead through sensors and estimate the possibility of a collision. If the system determines that the possibility of a collision is high, it will illuminate the collision warning system light through the sensors. Taking the Tiida TIIDA 2021 1.6L manual Ledong version as an example: the manufacturer of this car is Dongfeng Nissan, the level is compact car, the energy type is gasoline, the transmission is 5-speed manual, and the body type is 5-door 5-seat hatchback.
I noticed the anti-collision system light flashing on the Tiida, which is a warning signal indicating there may be an issue with the system. The most common cause is a dirty front sensor, such as dust, mud, or insect buildup, preventing the system from accurately detecting distance. Additionally, during severe weather, rain or fog may interfere with the sensor's functionality. There could also be a software error requiring an update, or low battery voltage affecting system operation. If ignored for too long, the system may fail, rendering it ineffective in emergencies and increasing the risk of rear-end collisions. It's recommended to start with a simple check—clean the sensor area near the front bumper, then restart the car to see if the light stops flashing. If the issue persists, visit a 4S shop or professional repair center for diagnostics. They can use a computer to read error codes and accurately fix the problem. Regularly maintain the sensor area during car washes to prevent similar issues.
The flashing of this collision avoidance system light is indeed unsettling, as it indicates a system malfunction, and you shouldn't rely on it completely while driving. I've encountered a similar situation where the light was flashing due to bird droppings covering the sensor, and it stopped after cleaning. However, if that's not the cause, you should consider issues like loose wiring or software faults. The system should automatically brake when detecting obstacles, but delays can occur when it's faulty, which is very dangerous. Especially at high speeds or in bad weather, extra caution is needed. It's recommended to pull over immediately to check if the sensors are dirty. If simple cleaning doesn't work, take it to a professional repair shop right away. Don't delay too long to avoid accidents caused by system failure. Regular maintenance can prevent such issues and ensure safe driving.
