Pre-Collision System Unavailable: What You Should Do?

If you have a car with a pre-collision system, it’s essential to know what to do if the system becomes unavailable.

Pre-collision systems help drivers avoid collisions by recognizing potential hazards and reacting accordingly. But what happens if the system fails?

Pre Collision System Unavailable

When your car’s Pre-Collision System (PCS) is unavailable, what should you do? 

The PCS system is a crucial safety feature in many newer cars. This system is designed to help drivers avoid or reduce the severity of collisions. 

If your car’s PCS is unavailable, you should still drive carefully and defensively. Remember that you are responsible for driving safely and avoiding collisions, even with the PCS system.

Why Is My Pre-Collision Light On?

If the pre-collision light is on, the vehicle’s sensors have detected an obstacle, and the driver should slow down and be prepared to stop.

Sometimes, the pre-collision light may also be accompanied by a warning sound or message. However, if the pre-collision light is on, it is essential to avoid sudden braking or steering, as this could cause an accident.

How To Fix The Pre-Collision System Unavailable Issue?

If you’re having trouble with your car’s Pre-Collision System (PCS) and it’s unavailable, there are a few things you can do to fix the issue.

First, check the PCS fuse in the engine compartment. If it’s blown, replace it with a new one.

Next, check for any loose wires or connections at the PCS sensor behind the front bumper. If you find any, tight them up or replace them as needed.

Finally, reset the PCS system by disconnecting and reconnecting the battery if all else fails. This should clear any errors and hopefully get your PCS working again.

If you follow these steps and your Pre-Collision System is still unavailable, it’s best to take your car to a qualified mechanic or dealership for further diagnosis.

Causes Of The Pre-Collision System Unavailable In Your Car

Pre-collision systems are designed to help avoid or mitigate the severity of a crash, but they’re not perfect. There are several reasons why your pre-collision system may fail to work correctly.

Turning On and Off Pre-Collision System

Faulty Wiring.

One of the most common causes of a pre-collision system unavailable error is faulty wiring. This can occur for various reasons, including faulty installation, damage to the wires, or simply age and wear.

If your PCS is displaying this error, it’s crucial to have a professional inspect the wiring to see if it is the cause. In many cases, simply replacing damaged or worn wires will fix the problem.

Failed Sensor.

Another common cause of a pre-collision system unavailable error is a failed sensor. The sensors on your PCS detect obstacles in front of your vehicle and trigger the system to engage.

If one of these sensors fails, it can prevent the system from working correctly. In some cases, simply replacing the faulty sensor will fix the problem. However, in other cases, you may need to replace the entire pre-collision system.

Outdated Software.

Another common reason the pre-collision system becomes unavailable in your car is simply that the software needs to be updated. The pre-collision system uses sensors to detect obstacles in the road and will automatically brake if necessary to avoid a collision.

However, over time these sensors can become less accurate, and the software that interprets the data collected by the sensors can also become outdated.

As a result, it’s essential to ensure that you keep your car’s software up-to-date to maintain the accuracy of the pre-collision system. You can usually take your car to the dealer or an authorized service center for a software update.

Damaged Components.

Pre-collision systems are an essential safety feature in many modern cars, but they can sometimes become unavailable due to damage. One of the most common causes of this is a damaged sensor, which can be caused by a car accident or even by parking too close to objects like garage walls.

Another potential cause is damage to the pre-collision system’s control unit, which is often located in the car’s bumper. If this unit is damaged, it may prevent the pre-collision system from working correctly.

In some cases, the entire pre-collision system may need to be replaced if it becomes damaged beyond repair.

Fortunately, many car manufacturers offer extended warranty coverage for pre-collision systems, so it’s worth checking with your car’s manufacturer if you’re concerned about this issue.

Poorly Designed System.

Most new cars come with a pre-collision system designed to help avoid or mitigate the severity of a crash. These systems use sensors to detect an imminent collision and then take action to either warn the driver or automatically apply the brakes.

However, these systems are not perfect, and there are some reasons why they might become unavailable in your car. One common cause is simply a dirty sensor.

It can’t function properly if the sensor is covered in dirt, snow, or debris. Another possibility is that the manufacturer may have turned off the system to prevent false alerts.

In some cases, the system may also be unavailable due to a software update that has not yet been installed. Whatever the reason, it’s essential to understand that pre-collision systems are not foolproof and should not be relied upon to avoid all accidents.

If the pre-collision system is unavailable, there are still things you can do to minimize the damage caused by a car accident. By following the simple tips we discussed above, you can help protect yourself and your passengers from serious injury in the event of an accident.

How to activate pre-collision in your vehicle?

You’ll need to consult your owner’s manual to activate the pre-collision system in your car.
The exact steps may vary depending on your make and model of the car, but typically you’ll need to go into the car’s settings and turn on the pre-collision system.

How to clean a pre-collision sensor?

You can clean the pre-collision sensor using a compressed air duster. Make sure to hold the duster at least 18 inches away from the sensor and spray in short bursts. Use a soft cloth to wipe down the sensor if needed.

At what speed is pre-collision assist active?

Pre-collision assist is active when the car drives at speeds of 3 mph or greater.
