Welcome to our guide on Toyota RAV4 Pre-Collision System Malfunction Reset.
If you own a Toyota RAV4, you know that the Pre-Collision System (PCS) is a vital safety feature that helps prevent accidents.
However, when the PCS malfunctions, it can be frustrating and dangerous.
In this article, we will provide you with a step-by-step guide on how to reset the PCS malfunction warning light.
We will also discuss how the PCS works, common issues that could cause the PCS to malfunction, and how to avoid them.
So, let’s dive in and learn how to reset your Toyota RAV4’s PCS malfunction warning light.
How does pre-Collision System work on Toyota RAV4?
The Pre-Collision System (PCS) in Toyota RAV4 is a safety feature designed to help reduce the risk of a frontal collision or lessen the impact of a collision. It typically consists of a combination of sensors, cameras, and radar technology. While specific details may vary based on the model year and trim level, the general operation of the Pre-Collision System involves the following components:
Radar Sensors
The system often includes radar sensors located in the front grille or bumper area of the vehicle. These sensors emit radio waves and measure the distance between your vehicle and the vehicle or object ahead.
Forward-Facing Camera
A forward-facing camera, usually mounted near the rearview mirror on the windshield, is employed to recognize and identify objects, such as other vehicles or pedestrians, in the vehicle’s path.
Laser Sensor (optional)
Some models may include a laser sensor to enhance the system’s ability to detect and identify objects in front of the vehicle.
System Computer
The information gathered by the radar sensors and camera is processed by a central computer or control unit. This unit analyzes the data to determine if there is a risk of a frontal collision.
Warning and Pre-Collision Preparation
If the system detects a potential collision, it activates visual and audible warnings to alert the driver. The warnings serve as an initial alert to encourage the driver to take evasive action.
Automatic Brake Assistance
In certain situations, if the driver does not respond to the warnings and the system determines that a collision is imminent, it can automatically apply the brakes to help reduce the vehicle’s speed and mitigate the impact.

The key steps in the operation of the Pre-Collision System are:
- Detection: The system continuously monitors the road ahead using the radar sensors and camera, identifying potential collision risks.
- Warning: If the system determines that a collision is likely, it issues warnings to the driver through visual and audible alerts.
- Pre-Collision Preparation: If the driver fails to respond and the system determines that a collision is imminent, it can activate pre-collision preparation measures, such as pre-charging the brakes and adjusting seat belt tension.
- Automatic Braking: In certain circumstances, the system can automatically apply the brakes to either prevent a collision or reduce its severity.
Where is the pre-collision assist sensor located On Toyota Rav4?
Specific details about the location of sensors on a particular car model may vary based on the model year and trim level. In general, the Pre-Collision Assist system in Toyota vehicles, including the RAV4, typically utilizes a combination of sensors, cameras, and radar.
The sensors for the Pre-Collision Assist system are often located behind the front grille or within the front bumper area. These sensors help the system detect obstacles, pedestrians, or other vehicles in the vehicle’s path, allowing the system to provide warnings or intervene if a potential collision is detected.
Toyota RAV4 Pre-Collision System Malfunction Reset: A Step By Step Guide
If you are experiencing issues with the pre-collision assist system in your Toyota RAV4, it is recommended to take your vehicle to an authorized Toyota dealer for inspection and repair. However, if you want to try resetting the system yourself, here are some steps you can follow:
- Reset the vehicle: Turn off the engine and remove the key from the ignition. Wait for a few minutes before restarting the vehicle.
- Reset or recalibrate the Pre-Collision System: Press the “PCS” button on the dashboard to turn off the system. Then, press and hold the button again until you hear a beep. This should reset the system. If the issue persists, you may need to recalibrate the system by following the instructions in your owner’s manual.
- Investigate the sensors: Check the sensors located in the front grille or bumper area for any damage or debris. Clean the sensors with a soft cloth if necessary.
- Check your ABS and Airbag Sensor: If the above steps do not work, check your ABS and airbag sensors for any issues. A faulty airbag sensor may also be an issue that will give your Pre-Collision System fits.
- Call in a professional: If none of the above steps work, it is best to take your vehicle to an authorized Toyota dealer for further inspection and repair.

Where are the sensors on a Toyota pre-Collision System?
The pre-collision assist sensor on a Toyota Rav4 is typically located in the front grille or bumper area.
Why is my Toyota Rav4 collision warning light on?
If the collision warning light in your Toyota RAV4 is illuminated, it indicates that there may be an issue with the Pre-Collision System or Forward Collision Warning (FCW). The reasons for the warning light can vary, and it’s essential to address the issue promptly. Here are some common reasons why the collision warning light might be on:
-
Sensor Obstruction
The sensors used by the Pre-Collision System, such as radar sensors or cameras, may be obstructed by dirt, snow, or debris. Inspect the front grille and bumper area for any blockages and clean the sensors if necessary.
-
Windshield Obstruction
The Forward Collision Warning (FCW) camera is often located near the rearview mirror on the windshield. Ensure that there are no obstructions, such as stickers or dirt, in the camera’s field of view.
-
System Malfunction
There could be a malfunction or fault within the Pre-Collision System. This may require a diagnostic scan by a qualified technician to identify and address the specific issue.
-
Electrical Issues
Problems with the electrical components of the system, such as wiring or connectors, may lead to the warning light. A thorough inspection of the electrical components may be necessary.
