The Toyota Pre-Collision System (PCS) is an advanced safety technology designed to help drivers avoid or mitigate collisions with other vehicles or pedestrians.

However, this system uses a combination of radar and camera sensors to detect potential collisions and alerts the driver through audible and visual warnings.

It is a safety system made by human beings to keep everyone alert.

To explain better, here are three key benefits of the Toyota Pre-Collision System:

  • Increased Safety: The primary benefit of the PCS is increased safety for both the driver and other road users. The system can detect and warn the driver of potential collisions, giving them time to react and avoid the accident.
  • Reduced Collision Costs: The PCS can help reduce the cost of collisions. By alerting the driver of potential collisions and automatically applying the brakes if necessary, the system can reduce the severity of accidents, leading to less damage and lower repair costs.
  • Peace of Mind: With the PCS, drivers can have peace of mind knowing that they have advanced safety technology working to keep them safe on the road. The system is always on and ready to detect potential hazards, so drivers can focus on the road ahead without worrying about collisions.

If a Toyota Pre-Collision System Malfunction occurs, it is recommended to take the vehicle to an authorized Toyota dealership for diagnosis and repair.

Attempting to reset or fix the system on your own may result in further damage or safety risks.

5-Symptoms of Toyota Pre Collision System Malfunction

The pre collision system in a Toyota vehicle is an advanced safety feature to alert the driver and help him avoid any collisions.

It works when there is a person on the road or if any obstacle or vehicle comes in the way.

However, like any other electronic system, the PCS may experience malfunctions or errors that could affect its functionality.

A normal person may not be able to analyze what’s wrong with the vehicle.

Therefore, its essential that he should understand the situation and realize how the pre collision system is malfunctioning.

For this reason, here are five major symptoms that could indicate a malfunction in the Toyota Pre-Collision System:

1. PCS Warning Light:

The PCS warning light on the dashboard serves as a system error indication. If the warning light illuminates and remains illuminated, there could be a systemic issue.

2. False Alarms:

The PCS is designed to detect potential collisions and alert the driver through audible and visual warnings.

However, if the system is malfunctioning, it may generate false alarms or warnings, even when there is no potential collision.

3. Lack of Response:

If the PCS isn’t functioning properly, it won’t be able to respond when required.

For instance, if the system identifies a likely accident but does not apply the brakes or warn the driver, a system problem may be present.

4. Problems With The Braking System:

The PCS cooperates with the car’s braking system. The performance of the PCS may be impacted if the braking system has problems.

For instance, the PCS might not be able to effectively activate if the brakes are not reacting as they should.

5. System Deactivation:

The system may turn off by itself if the PCS faults regularly. This could be a safety measure to stop the system from harming or generating further problems in the future.

Even if there is a probable accident, the system will not apply the brakes or issue any warnings if it deactivates.

It is advised to take the car to a certified Toyota dealership for diagnostic and repair if any of these symptoms appear.

Self-help system repairs might lead to greater damage or safety issues.

You must know that resetting the Toyota Pre-Collision System (PCS) should only be done by a certified technician at an authorized Toyota dealership.

Attempting to reset the system on your own could result in further damage or safety risks.

But, still if you believe that you the problem must be fixed as soon as possible, then here is a detailed process to analyze the problem and fix it before anything else goes wrong.

Step 1: Diagnose the Problem

At first, you have to thoroughly examine the Toyota Pre-Collision System during the problem analysis phase to find any problems that might have led to the failure.

The system’s parts, including the cameras and radar sensors, will be visually inspected as part of this examination to look for any damage or signs of wear and tear.

Also, you will have to utilize diagnostic tools to read any fault codes or error messages that the system may have produced.

Once the fault codes or error messages are identified, you can use the info to interpret the data and determine the root cause of the malfunction.

This may involve additional testing or troubleshooting to pinpoint the exact issue that is causing the system to malfunction.

Step 2: Address the Issue

Once the cause of the malfunction is found, you can address the issue.

Depending on the cause of the malfunction, you will need to replace a faulty sensor or component, recalibrate the system, or perform other repairs.

It is crucial to keep in mind that solving the issue may need doing more than just repairing or replacing the damaged parts.

For instance, you might need to update the software or re-program the system to ensure it is running properly if a software error caused the issue.

Step 3: Clear the System’s Memory

You must wipe the system’s memory after resolving the problem.

By doing this, you can make sure that any fault codes or error messages that the system may have produced are eliminated.

Due to this, the system starts over with a clean slate. Any dashboard alerts or messages will be reset if the system’s memory is cleared.

Step 4: Calibrate the System

Once the memory is cleared, you can calibrate the system. This involves resetting the system’s parameters to the manufacturer’s specifications.

Calibrating the system ensures that all of the sensors and components are working together correctly and that the system is accurately detecting potential collisions.

Step 5: Road Test the Vehicle

After everything is set, you can put the car through a road test after calibrating the system to make sure the PCS is working correctly.

Make sure to activate the PCS during the road test for identifying possible crashes and alerting the driver as planned.

Step 6: Verify That Everything Is Fine

After the test, you can confirm that the repair was effective when the road test is finished.

This entails verifying that the problem has been fixed by examining the system’s memory and error codes again.

The repair is done if everything is running well and there are no more problems.

But it is important to remember that resetting the Toyota Pre-Collision System should only be done by a certified technician at an authorized Toyota dealership.

Attempting to reset the system on your own could result in further damage or safety risks.

Additionally, if any symptoms of a PCS malfunction occur, don’t wait for too long before it poses more threat.

Toyota Pre Collision System Not Working, What to Do!
