A secondary brake collision system is a safety measure that activates if your car encounters an accident.
Currently, all the cars in the market have this system installed.
The system prevents extreme damage and is a protocol that ensures that safety remains maximum for driver and front-seat passengers.
The function of this brake system depends upon the primary collision. It serves as a threshold for activating these brakes.
If the system works efficiently, it reduces the vehicle speed at the collision point. As a result, impacts decrease significantly.
The step is also necessary to ascertain that any property of another vehicle nearby does not experience a severe collision.
However, the secondary brake collision system malfunction is quite prevalent, and we need a viable solution.
Causes Of Secondary Brake Collision System Malfunction
Several reasons could lead to the failure of the secondary brake collision system. Following are some of them.
Faulty Primary Collision Radars
The system responsible for activating the secondary brakes is the primary collision system.
The secondary brake collision system malfunction arises due to faults in the front components.
It has radars present in the frontal end and a camera that assists the overall system in assessing the situation of the accident.
The secondary brake collision system malfunction occurs if these radars and cameras do not function properly.
Moreover, snow is one of the most common obstacles that hinder the camera’s functioning.
However, the radar may damage for multiple reasons, including wiring issues or broken components.
Delay In The Airbag Opening
The airbags activate the sensors that allow the system to measure several aspects on the road and within the car.
They calculate the overall speed and figure out the exact timing and intensity of brakes to stop the collision.
Therefore, the airbags must open up on time to prevent a secondary brake collision system malfunctioning.
These also trigger the airbag control unit that generates the signals for the brake system.
If the airbag chamber is damaged or the control unit fails to carry out the job efficiently, the secondary brake collision system malfunctions.
Broken Cables
Your vehicle is a complex network of cables and wires that connect one system to another.
The integrity of each one is necessary to ensure that the car parts do not cause secondary brake collision system malfunction.
The wires for the secondary brake system are present underneath the automobile.
If they undergo damage or an animal chews them when your car is parked, they will be damaged. In such cases, the system fails to navigate the signals.
As a result, you may experience a slower response from the brake system, or it might not even work in the first place.
Slowed Down Process
The secondary brake collision system must work efficiently and instantly to prevent severe accidents.
The airbag sensors must immediately send signals to the relay centers to activate the collision system.
The entire procedure slows down due to several reasons.
The rusted metallic regions, the short circuits, or the exposed wires may all contribute to the secondary brake collision system malfunction.
Furthermore, the problem can also lie in any system’s components. These include the brakes, engine control unit, speed sensors, and collision determinants.
Damaged Connection
The whole system must coordinate effectively to stop the secondary collision. There are numerous components involved in the system that must function simultaneously.
Therefore, there is a powerful connection between them due to specific cables or sensors.
Nevertheless, the strength of this association is necessary for the functioning of the brakes.
The primary collision system and airbags initiate the process. Afterward, the speed assessing radar and the engine unit performs their function.
Moreover, the force the driver hits the accelerator and brake also generates a signal that eventually determines the collision intensity and activates the secondary system.
If this connection damages, the secondary brake collision system malfunctions.
Solutions To Secondary Brake Collision System Malfunction
You can follow the following steps to rectify secondary brake collision system malfunction.
Cleaning The Vehicle
There are several regions on the vehicle where dust gathers and destroys the car’s functionality.
The DTCs in the car alert you as certain areas become filled with dirt that hamper the mechanism of the sensors.
If you thoroughly wash your car or strictly focus on these openings, you can prevent the secondary brake collision system malfunction.
Therefore, you must thoroughly clean the car once in a while to avoid such instances.
Navigating The Cruise Control
The cruise control can also interfere with the brake system. If it considers the current speed optimum, you might face difficulty activating the brakes.
The system may not recognize the consistent and high increase in speed as one of the collision indicators. It keeps the car running on its constant acceleration.
Therefore, in such cases, you need to recalibrate the system.
Turning off the cruise control and then turning it on the back may assist you in solving the secondary brake collision system malfunction.
However, it may impact the battery and produce more bugs and issues. Thus, you must be cautious while carrying out this measure.
Turning Off Certain Features
The safety features usually do not kick in unless you have turned them off.
These options reach a frozen state where you cannot access them despite the proper functioning of your vehicle.
Therefore, you will have to revive them by turning them off first.
Find all the safety features and the way you can switch them off. Please keep them in this state for a few hours or a day.
Afterward, reactivate these controls. You may notice that the brake system will start working efficiently.
Calling The Experts
Secondary brake collision system malfunction occurs due to multiple reasons. The initial indicator of this failure is the sign present on the central meter.
It tells you to call your dealer because pinpointing the exact cause can be challenging.
Therefore, it is more appropriate to instantly get your vehicle to the manufacturers.
They assess the condition of your automobile on the computer.
It assists manufacturers in finding out the precise reason behind the secondary brake collision system malfunction.
Afterward, they can solve the issue without any confusion and inconvenience.
Turned Off Primary Systems
In some cases, the pre-collision system is turned off. It is essential to determine the impact of collision and direct the activation of secondary system brakes.
If you have a second-hand car, then there is a high probability that the last owner might have switched off the system.
Therefore, if the secondary brake collision system malfunctions, you must analyze the state of the primary or pre-collision sensors.
You can turn them on by following the instructions of the manufacturer’s guide or by contacting the professionals.
Conclusion
Secondary collision brake system malfunction occurs quite often in vehicles.
The system is essential to allow people to avoid secondary accidents that are highly prevalent and dangerous.
To ensure that the secondary brake collision system malfunction does not prevail efficiently, you should thoroughly clean the units and monitor changes in all the associated parts of the system.
Furthermore, if you have a faulty system, instantly get it rectified or drive slowly and steadily until you find a proper solution.
