What does it mean when a small red car icon flashes on the dashboard?

A flashing small red car icon on the dashboard indicates that the car's anti-theft system is active. When the car is turned off and locked, a red car-shaped indicator light on the dashboard flashes once every one to two seconds, which is a normal phenomenon, indicating that the car has entered the anti-theft mode. If it flashes while driving, it means that a door is not properly closed; if the indicator light stays on constantly, it indicates a malfunction in the anti-theft system. Here are some common issues with the car's anti-theft system: 1. No response when operating the anti-theft system with the remote: This is likely due to insufficient battery power in the remote, causing it to malfunction. Replacing the battery and trying again should resolve the issue. 2. Electronic signal interference: If the parking location has signal interference, the car may not respond to remote operations. In this case, move the car to another location and try locking it again. 3. Decreasing remote operation distance: When using the remote to unlock or lock the car, you need to be very close to the car to operate it. This is mostly due to low battery power in the remote, and replacing the remote battery should fix the problem.
A few days ago, I also encountered the flashing small red car icon on the dashboard while driving. After careful investigation, I found that the issue might be related to the braking system or stability control device. It could be due to a dirty or damaged ABS sensor, as dust accumulation can easily cause blockages, or perhaps a poor connection in the wheel speed signal harness, leading to false fault reports. Once this warning light flashes continuously, it means the emergency avoidance function might fail, which is particularly dangerous in rainy weather or on bumpy roads. Later, I went to the shop for a computer diagnosis and found that the sensor on the right rear wheel was stuck. Cleaning it resolved the issue. It's advisable not to drive too fast before checking, find a safe place to stop and restart the car. If that doesn’t work, head to a repair shop immediately to identify the specific cause.
When that blinking little red car icon lit up on my dashboard, my first thought was an issue with the chassis control system. It could be a detached wheel speed sensor, signal inaccuracy, or possibly interference from aged wiring. Don't ignore this situation, as both the anti-lock braking system and anti-skid modules rely on these signals. If faulty, the vehicle may skid during turns. Experience suggests pulling over safely, turning off and restarting the engine to see if the light disappears. If it keeps coming on, inspect all four wheel sensor connectors for oxidation or looseness, and replace components if necessary to ensure stable driving.
