- The VSC system relies on accurate wheel speed measurements to determine if a wheel is slipping.
- A faulty wheel speed sensor can provide incorrect information, causing the VSC light and check engine light to turn on.
2. Brake System Issues:
- Worn brake pads, low brake fluid level, or problems with the master cylinder or brake booster can impact the effectiveness of the braking system and trigger the VSC and check engine lights.
3. Steering Angle Sensor Malfunction:
- The steering angle sensor informs the VSC system about the direction in which the steering wheel is turned.
- A faulty steering angle sensor can provide incorrect data, leading to VSC and check engine light illumination.
4. Faulty VSC Control Module:
- The VSC control module processes information from various sensors and controls the VSC system's operation.
- A malfunctioning VSC control module can cause the VSC light and check engine light to come on.
5. ABS System Issues:
- Since the VSC system also utilizes the Anti-lock Braking System (ABS), problems within the ABS unit, such as faulty sensors or a malfunctioning ABS module, can activate the VSC and check engine lights.
6. Faulty Accelerator Pedal Sensor:
- The accelerator pedal sensor informs the VSC system about the driver's accelerator pedal inputs.
- A faulty pedal sensor can transmit incorrect data, triggering the VSC and check engine lights.
If your vehicle's VSC and check engine lights stay on consistently, it's advisable to have it diagnosed by a qualified mechanic using relevant diagnostic tools. Once the root cause is identified, the necessary repairs or replacements can be performed to resolve the issue.
