Subaru Security Light Flashing: Behind the Reasons and Solutions
Different car manufacturers incorporate safety systems to optimize each driver’s experience.
Among all of them, Subaru also has a safety system that works together with a safety alarm light. This safety light is responsible for always keeping the driver and passengers safe.
In such a way, this light can start flashing steadily when there is any inconvenience.
For anyone to be aware of what is happening outside or inside their vehicle, the following are the most common reasons for the security light to flash.
01. Security activated
In principle, the user can tell that his or her security system is working and armed when the security indicator light is flashing.
This indicator light may blink steadily once the vehicle is completely turned off and all its doors are closed, and this light will continue to flash until the driver enters the vehicle.
When it is a Subaru model, this light continues to blink from the time the ignition switch is in the off position.
This is usually the case with Subaru vehicles with a push-button start and keyless entry system. The security light may continue to flash at times when it should not.
When the security light continues to flash, the user may encounter a problem. If the security light is flashing, the vehicle cannot be used.
This security system prevents the car from being used by anyone. In this case, one of the fuses of this security system could be failing.
It could also happen that one of the vehicle’s sensors continues to operate when it should not.
In many instances, there could be a defect in the cabling or in the internal switches.
Of course, this security system can be very efficient in preventing anyone else from trying to start your vehicle.
02. Non-flashing security light
As we have mentioned, the security light indicates when the vehicle is protected because it is an anti-theft system.
For this reason, it is essential to identify when this safety light is not flashing.
If the vehicle is turned off, the flashing security light indicates that the system is active and working.
Conversely, when this security light is not flashing and is off, it may mean that the anti-theft security system is also disabled.
This may be a consequence of a dead or depleted battery. It is also possible to find a problem in the security system’s wiring that prevents the activation of the anti-theft system.
03. Safety light on
On certain occasions, the safety light may remain on without flashing. When this safety light is on and steady, it is a signal that the user needs to consider.
In this type of situation, the vehicle will also not move or even start. Hence, this situation indicates that a person has attempted to operate the car illegally.
Someone may have a duplicate key that the user has not authorized.
You can also consider that the security light on and fixed may result from the misuse of the system.
You may have made the wrong step in using your Subaru on certain occasions.
Therefore, it is recommended to read the Subaru vehicle owner’s manual to understand the complete operation of this anti-theft security system.
