What to Do When the Dashboard Flashes Red After Locking the Vezel?

Close the car door tightly again or remove any foreign objects. Below is relevant information about the dashboard flashing red: Cause: The red light is an indicator of the vehicle's anti-theft system. It will light up red when the car door is not closed tightly or when there is a foreign object blocking the door. Principle: A typical mechanical odometer is connected to a flexible shaft, which contains a steel cable. The other end of the flexible shaft is connected to a gear in the transmission. The rotation of the gear drives the steel cable to rotate, which in turn drives a magnet inside the odometer cover to rotate. The cover is connected to the pointer and, through a hairspring, positions the pointer at zero. The speed of the magnet's rotation causes changes in the size of the magnetic field lines. The balance is disrupted, thereby moving the pointer.
I noticed that the HR-V's dashboard flashes a red light after locking, which usually indicates the anti-theft system is active, showing the vehicle is in protection mode. However, if the flashing is too rapid or irregular, it's a cause for concern. I remember one time my car did this, and upon checking, it turned out the battery was aging, causing low power and system false alarms; another time, it was because a door wasn't shut properly, and reopening and closing it fixed the issue. I recommend first ensuring all doors, the trunk, and the hood are securely locked—especially the trunk, as it's often overlooked. Then, test the remote key's sensitivity. If the light continues to behave abnormally, try a simple method: measure the battery voltage (it should be above 12V normally; if it's below 11V, it needs replacement). Safety first—persistent red flashing can drain the battery, leading to starting issues. During regular maintenance, check the anti-theft module and keep the sensors clean to prevent problems.
