Why Acura Check VSA System Light Become On – 7 Reasons To Check

The VSA light in your car could turn on for a variety of reasons. This is a list of the most typical causes:

1. Insufficient Brake Fluid

 Brake Fluid
Insufficient Brake Fluid

The hydraulic pressure created by the brake fluid is what drives the VSA system. There might not be enough pressure to operate the VSA system when the brake fluid level is low, turning on the warning light.

According to a report by Honda Motor Company, when the brake fluid level falls below a specified limit, the sensor sends a signal to the electronic control unit (ECU).

The ECU then turns on the VSA warning light on the dashboard to notify the driver of the low brake fluid level.

2. An Unreliable Steering Angle Sensor

In an Acura, the steering angle sensor detects the steering wheel’s angle and sends that information to the VSA control module. This determines the direction and amount of wheel rotation.

If the sensor is faulty, it can send incorrect signals to the VSA control module, which can affect the vehicle’s stability and trigger the warning light.

The VSA modulator control unit controls the hydraulic pressure in the braking system, which is essential for the efficient operation of the VSA system.

If the control unit malfunctions, it can cause a loss of hydraulic pressure or incorrect pressure regulation, which can affect the VSA system’s performance.

4. Low Battery Voltage

Low battery voltage can damage the VSA system’s capacity to receive and interpret information from the wheel speed sensors and control the brake pressure. This can result in the VSA light turning on in an Acura.

5. Wheel Speed Sensor Issues

The VSA system uses wheel speed sensors to assess each wheel’s speed and compare it to the other wheels to determine the direction and stability of the vehicle. 

The VSA control module may interpret the data incorrectly and activate the warning light if one sensor gives the wrong signals.

6. Uniform Wheel Size

According to a study, if the wheel sizes on your car are not uniform, the rotational speed of each wheel can vary, which can trigger the VSA system. This can cause the VSA light to turn on.

7. Worn Brake Pads

The functionality of the ABS and VSA systems can be impacted by worn braking pads. When the brakes are applied, the ABS and VSA systems work together to maintain control and stability by modulating the brake pressure to each wheel. As a result, the VSA light may turn on to indicate a problem.
