Toyota Pre Collision System Malfunction Reset

If you’re reading this, chances are you’ve encountered a frustrating issue with your vehicle’s Pre Collision System.

You may have seen a warning light pop up on your dashboard, or perhaps you’ve noticed that your car’s safety features aren’t working as they should be.

Whatever the case may be, you’re probably wondering what you can do to fix the problem and get back on the road with confidence.

Luckily, resetting a malfunctioning Pre Collision System is usually a simple process that you can do yourself.

In this article, we’ll walk you through everything you need to know to get your Toyota’s safety features back up and running and explain why it’s crucial not to ignore the warning signs.

5 Common Signs of a Malfunctioning Pre Collision System

Here are some common signs that indicate a malfunctioning Pre Collision System:

1. Warning Light

The most obvious sign of a malfunctioning Pre Collision System is the appearance of a warning light on the dashboard. This light is usually yellow or orange and is shaped like a car with lines in front of it.

2. Unresponsive System

Another sign of a malfunction is an unresponsive Pre Collision System. If you notice that the system is not activating when it should be, it could be a sign that something is wrong.

3. False Alarms

A malfunctioning system can also result in false alarms, triggering the Pre Collision System even when there is no actual danger. This can be frustrating for drivers and can cause them to lose confidence in the system’s accuracy.

4. Inconsistent Braking

The Pre Collision System relies on the brakes to bring the vehicle to a stop when a potential collision is detected. If you notice that the brakes are inconsistent or not working as they should be, it could be a sign that the system is malfunctioning.

5. Strange Noises

 Finally, a malfunctioning Pre Collision System can sometimes result in strange noises coming from the vehicle. This could result from the sensors picking up false readings or other issues within the system.

Causes of Toyota Pre Collision System Malfunction Reset

If you’re experiencing a Toyota Pre Collision System malfunction reset, it’s essential to understand the possible causes of the issue. Here are some of the common reasons why you may be experiencing a reset:

1. Sensor Issues

The Pre Collision System relies on sensors to detect potential collisions. These sensors can sometimes malfunction or become dirty, reducing their effectiveness. The system may also fail to detect a potential collision if snow, mud, or debris blocks any of the sensors.

2. Electrical Problems

The Pre Collision System uses various electrical components, such as wiring, fuses, and connectors, to operate. Any damage to these components can cause the system to malfunction or fail to function at all. It’s important to have a qualified technician diagnose any electrical problems to avoid further issues.

3. Software Glitches

As with any system that uses software, the Pre Collision System may experience glitches or bugs that cause it to malfunction. Toyota may have released updates to fix these issues, and it’s essential to keep your system up-to-date to avoid any malfunctions.

4. Calibration Issues

The sensors in the Pre Collision System need to be calibrated correctly to function effectively. Any issues with the calibration can cause the system to malfunction or fail to detect potential collisions. It’s important to have a qualified technician calibrate the system to ensure it’s working correctly.

5. Mechanical Problems

The Pre Collision System relies on various mechanical components to function correctly. Any damage to these components, such as brakes or suspension, can cause the system to malfunction or fail to detect potential collisions.

How to Reset Toyota Pre Collision System Malfunction

1. Stop the Vehicle

To reset the system, you must first come to a complete stop and turn off the engine.

2. Remove Key

Once the vehicle is turned off, remove the key from the ignition and wait for about 30 seconds before proceeding to the next step. If your vehicle has a push-button start, you can simply press and hold the “Engine Start/Stop” button for about 3 seconds until the engine turns off.

3. Restart the Vehicle

After waiting 30 seconds, restart the engine and ensure all warning lights on the dashboard have turned off.

4. Test the System

Take the vehicle for a test drive and ensure that the Pre Collision System functions as it should be. Test the system by intentionally driving close to an object to see if the system will activate the brakes automatically.

Tips on what to do if the reset process fails

Here are some tips on what to do if the reset process for the Toyota Pre Collision System Malfunction fails:

1. Try Again

If the reset process fails, try the procedure again, making sure to follow the steps precisely. Sometimes, the system may have been reset improperly, which can lead to the system failing to reset correctly.

2. Check for Software Updates

If the reset process fails again, check if there are any available software updates for the vehicle. The Toyota Pre Collision System uses software to operate, and updates can fix glitches and other issues that might be causing the malfunction.

3. Check for Obstructions

Ensure that the sensors are clean and free of any obstructions that could be causing the malfunction. Dirt, snow, and debris can interfere with the sensors, making them unable to detect potential collisions.

4. Consult a Technician

If the above tips fail, it’s best to take the vehicle to a qualified technician for a thorough diagnosis. A professional technician can identify and fix the issue with the Pre-Collision System.

Why You Shouldn’t Ignore a Malfunctioning Pre Collision System

Ignoring a malfunctioning Pre Collision System can be dangerous, and here are some reasons why:

1. Increased Risk of Accidents

The Pre Collision System is designed to prevent or reduce the severity of accidents by detecting potential collisions and automatically applying the brakes. If the system is not working correctly, you may not receive a warning when approaching a potential collision, increasing the risk of accidents.

2. Reduced Confidence in the System

A malfunctioning Pre Collision System can also reduce your confidence in the system, causing you to rely less on it or turn it off altogether. This can put you at an even greater risk of accidents since the system is no longer there to provide an additional layer of safety.

3. Expensive Repairs

Ignoring a malfunctioning Pre Collision System can lead to more significant problems that may require expensive repairs. Fixing the issue early on can help prevent further damage and costly repairs.

4. Safety Recalls

In some cases, a malfunctioning Pre Collision System can be due to a safety recall. Ignoring the issue may mean missing out on a free repair or replacement offered by Toyota.

5. Legal Liability

If you’re involved in an accident where the Pre Collision System was malfunctioning, you may be held legally liable if you were aware of the issue and did not address it.

Why Did My Pre Collision System Light Come On?

The Pre Collision System light may come on due to problems in the Pre Collision system such as sensor issues, calibration issues, electrical problems, or software glitches. It’s important to have the issue diagnosed and fixed by a qualified technician to avoid any potential safety hazards.

Where Is the Pre Collision Assist Sensor Located?

The location of the Pre Collision System (PCS) sensors is usually behind the front grille or in the front bumper area.

Can You Turn off Toyota Pre Collision System?

Yes, you can turn off the Toyota Pre Collision System (PCS) temporarily using the PCS on/off button located on the dashboard.

However, it’s important to note that Toyota recommends always leaving the system on for optimal safety. If you need to turn off the PCS for a specific reason, such as driving in certain road conditions or during maintenance or repairs, it’s essential to turn it back on as soon as possible.
