The alarms are placed in the cars to protect them from unwanted visitors, offer effectiveness when it comes to opening the doors or trunks at times of theft, or robberiesApart from the sound they emit, they block access if you don’t have the correct device that allows entry. Know what are the common car alarm failures.
6 common failures in car alarms
Alarms are security devices installed in cars to protect their integrity, however, they are not safe from suffering from some common failures, which we will mention below:
1. Wiring problems
Various can occur alarm console circuit problems due to faulty wiring. This leads to the alarm sounding even without touching the vehicle.. The alarm can be stopped by turning off the button on the device located under the steering wheel. However, if this action does not solve the fault, it is best to remove the alarm fuse. The alarm fuse box is usually located under the steering wheel on the left side. However, in many car models the fuse box for the alarm system is located under the hood. To check the fuse, you can extract it from the fuse holder with fine nose pliers. If you detect that it is due to a blown fuse, it is best to replace it immediately.
2. Alarm system programming
Ultimately, turning off the car, removing the keys, and disconnecting the battery, removing the two cables that feed the vehicle (positive and negative connector), can solve it. For this, using a wrench proceed to unscrew the side nut of each connector. Negative side first, connect the battery. It is a useful method especially when the alarm sounds when the car is stopped or sounds at night.
3. Alarm that refuses to go off
When you accidentally lock your car with the remote, you may notice an LED flashing, without making any noise. A Brightly glowing LED means the car alarm system is on, different is that it doesn’t make any sound. It should be checked that the panic button on the remote control is working correctly or not, if it works, it means that the horn is not faulty. The wrong alarm mode may have been activated. It is best to refer to the user manual to correct the error, meanwhile keep pressing the right key on the remote control. Using needle nose pliers, remove the fuse from the box, if you do not know which is the fuse for the alarm system, proceed with trial and error, until you locate the correct fuse, remove the fuse, and disable the alarm. If it doesn’t work, then you need to disconnect the negative terminal of the car battery to disable it..
4. Alarm in valet mode
A car alarm in valet mode means that the buttons and the system screen are locked to protect the data (settings). It is a common situation that occurs in alarms, it occurs when the button to activate or deactivate the control is pressed and the lights do not only flicker, it can also be detected that the electrical locks are activated, resulting in more than a failure. A alarm in valet mode only the electric locks work and the lights begin to flash.
usually this function must be activated when the vehicle is taken to a workshop or place where it is going to be repaired, for maintenance, so that when opening and closing the doors the alarm does not activate and start to soundIn this case, only the insurances remain activated. This option will depend on the configuration of the alarm system, for example, for this type of alarm, the way to remove this valet mode is to press the asterisk button
for three continuous seconds, then the trunk button is pressed to cycle the alarm into and out of valet mode. Another option to remove this function if it were for the configuration, is to use the valet button, it is a small button that many cars have, and it is used to activate and deactivate functions, generally, opening the ignition switch or switch, is pressed several times, this will confirm that the failure is not due to configuration or activation of functions. Equally,The car’s lights should be checked to detect that they work correctly, if everything is fine, then it is likely that it is caused by a burned-out bulb or a loss of ground on the side of the bulbs.
. If this were the case, the alarm module should be checked to locate the cable corresponding to the output of the direct signal to the lights that falter, almost always these cables have a fuse.
Common failures in car alarms At other times the alarms are activated and deactivated, it is generally very common for the alarm not to respond, not even the power locks activate,It can occur for various reasons, the most frequent is because the control batteries have run out . You can make sure, when the buttons are pressed and the lighting is very low, it is best to replace the batteries.A battery with little charge does not have the capacity to supply and send the signal to the module, making it obvious that the alarm does not work
.
To check the main power of the fuse, that is, that it has constant current, the test lamp is placed, connected to the negative side or any metal part of the car, immediately proceed to verify that the power is correctly reaching the module. The negative input is also required, for this the positive of the battery must be placed, it is verified that it has the negative signal in the cable that goes to the alarm, if it reaches the test lamp correctly, it lights up.
6. Alarm fail to open latches
Likewise, another failure may occur in the alarm to open the locks, it may not allow any of the doors to work, or a specific door, perhaps it is due to the actuators because the adapter has broken, or some problem in the connections of the adapter. If you are facing an event where the locks do not open or close, it may be due to a configuration or activation failure. Although, if this has been ruled out, the next thing to do is check the module for the signal that comes out of the cables, or connection failures at some point in the circuit that has opened, or burned a cable.
