Car safety is a top priority for drivers, and with the advancement of technology, the pre-collision system (PCS) has become an essential safety feature in modern cars. The PCS uses sensors to detect obstacles and pedestrians on the road ahead and alerts the driver to take necessary action to avoid a potential collision.
However, if the PCS becomes unavailable due to dirty sensors, it can be a safety hazard.
In this article, we will discuss what causes the PCS to become unavailable due to dirty sensors and how to clean them.

Understanding the Pre-Collision System
The pre-collision system (PCS) is a safety feature that uses sensors to detect obstacles and pedestrians on the road ahead. The system warns the driver of a potential collision by sending visual and audio alerts.
In some cases, the PCS can automatically apply the brakes to avoid a collision. The system is designed to reduce the risk of accidents and injuries on the road.
Causes of the Pre-Collision System Unavailability
Dirty Sensor Issue and Its Impact on the PCS
The PCS relies on a series of sensors located in the front of the car to detect obstacles and pedestrians.
These sensors work by emitting a signal that bounces back off of objects in front of the car.
If the sensors are dirty or obstructed, they may not be able to detect obstacles or pedestrians, causing the PCS to become unavailable.
Other Factors that May Cause PCS Unavailability
There are other factors that may cause the PCS to become unavailable. For example, if the sensors are damaged or malfunctioning, they may not be able to detect obstacles or pedestrians.
Additionally, extreme weather conditions, such as heavy rain or snow, may also affect the sensors and cause the PCS to become unavailable.
Risks Associated with a Dirty Pre-Collision System
When the PCS becomes unavailable due to dirty sensors, there are significant risks associated with driving. Without the PCS, drivers may be less aware of obstacles and pedestrians in front of them, increasing the risk of accidents and collisions.
Additionally, driver-assist systems, such as automatic emergency braking, may not function properly if the PCS is unavailable.
How to Clean the Pre-Collision System Sensor
To ensure that the PCS is functioning properly, it’s important to keep the sensors clean. Here are some steps to clean the sensors at home:
- Locate the sensors on the front of the car. They are usually located near the bumper.
- Use a soft, damp cloth to wipe the sensors clean. Be gentle and avoid using any abrasive materials that could scratch the sensors.
- Dry the sensors with a clean cloth.
If the sensors are heavily soiled or obstructed, it may be necessary to take the car to a professional for cleaning.
Preventing Pre-Collision System Sensor Issues
To prevent the PCS from becoming unavailable due to dirty sensors, it’s important to maintain the sensors regularly. Here are some tips to help:
- Clean the sensors regularly, especially during the winter months when they may become covered in snow or ice.
- Avoid parking the car in areas with lots of debris or dust.
- Check the sensors during routine maintenance appointments.
Regular maintenance and sensor check-ups can help prevent PCS unavailability due to dirty sensors.
What does LTA unavailable clean sensor mean?
LTA stands for Lane Tracing Assist, which is a safety feature found in some modern cars that uses cameras and sensors to help keep the car centered in its lane. “LTA unavailable clean sensor” typically refers to a warning message that appears on the car’s dashboard display when the LTA system is unavailable due to dirty or obstructed sensors.
The message is telling the driver that the LTA system cannot function properly until the sensors are cleaned or the obstruction is removed. It’s important to address the issue promptly and clean the sensors to ensure that the LTA system is functioning properly and to maintain safe driving practices.
The pre-collision system is a critical safety feature in modern cars that can help reduce the risk of accidents and collisions. However, when the PCS becomes unavailable due to dirty sensors, it can be a safety hazard. By understanding the causes of PCS unavailability and taking steps to clean and maintain the sensors, drivers can ensure that the system is functioning properly and keep themselves and others safe on the road.
