What is the reason for the continuous flashing of the Leiling anti-theft indicator light?

The reason for the continuous flashing of the Leiling anti-theft indicator light is that the vehicle's anti-theft system has been activated. Unlocking and opening the door with the key can eliminate this issue. The Leiling is a compact 4-door, 5-seater sedan with the following body dimensions: length 4640mm, width 1780mm, height 1455mm, and a wheelbase of 2700mm. The Leiling is equipped with a 1.2T turbocharged engine and a CVT continuously variable transmission, delivering a maximum power of 85 kW and a maximum torque of 185 Nm. It features front-wheel drive, with a front suspension using MacPherson independent suspension and a rear suspension utilizing an E-type multi-link independent suspension.

The Leiling anti-theft indicator light flashing continuously is usually because the anti-theft system is in alert mode. I own a Toyota and have encountered similar situations, which are typically caused by low battery in the key or poor key recognition. If the anti-theft system is activated, this light will keep flashing to remind that the vehicle is locked to prevent theft. Other common causes include doors not being closed properly or sensor issues, such as a loose trunk latch or windows not being fully closed, which can also cause the indicator light to flash continuously. If it flashes for a long time, it might indicate a fault in the ECU or control module, requiring professional inspection. I always advise friends to check the key first—try replacing it with a new battery. If that doesn’t solve the issue, check if all doors are securely closed. Regular maintenance of the vehicle’s electrical system can prevent such annoyances in daily use; otherwise, the flashing indicator light during nighttime parking can be unsettling. Safety comes first—never overlook small details.

The flashing of the anti-theft indicator light primarily indicates that the vehicle's anti-theft mechanism is active or experiencing an abnormality. Based on my knowledge, this usually means the system has entered a security mode, such as when you leave the car without properly locking it, triggering the sensors to activate the indicator light to warn of potential intrusion. Another common reason is a low battery in the key—many modern car keys use smart sensing technology, and once the battery is low, it cannot send the correct signal, causing the light to flash. Additionally, it's important to check if the car doors are fully closed; even a small gap can cause the sensor to misjudge. System issues like ECU faults are less common but cannot be ruled out; it's recommended to test with in-car tools or use a spare key to unlock. If the light keeps flashing without stopping, visit a 4S shop promptly to avoid affecting overall safety. Remember to keep the key battery charged and regularly clean dirt around the door locks.

This issue is quite common. A flashing light usually indicates anti-theft system activity or a minor glitch. Start with the basics—ensure all doors and the trunk are securely locked, as an unlatched one can trigger the indicator. Next, check if the key fob battery is worn out; replacing it might solve the problem. If the light persists, it could be a wiring short circuit or sensor issue requiring professional inspection. In such cases, I always try starting the car with a spare key first to see if it helps. It's advisable to address this promptly to prevent the system from continuously issuing error alerts, which can affect battery life. Safe driving relies on meticulous maintenance.
