Many drivers have encountered the message to check VSC Lexus ES 350. They worry the problem is dangerous because VSC’s function is to control their cars.
Once the VSC system detects that your vehicle is losing traction, it will immediately decrease the engine power of particular wheels.
Thus, you can avoid an accident. But is the alarm message really serious?
This article will give information about the check VSC system, what triggers it, and how to repair it.
What Is VSC?
Vehicle stability control is a technology found in many Lexus and Toyota Camry vehicles meant to keep the car from skidding and sliding in adverse weather conditions.
During prolonged rain, the roadways become wet and slippery, making it difficult for tires to get friction.
Vehicle Stability Control, or VSC, is responsible for keeping your car from sliding across the road. The VSC’s goal is to provide brakes to the vehicle’s wheels and keep it from sliding on the street.
If the VSC system detects the vehicle is losing friction, it will immediately cease engine power from particular wheels. It will correct your vehicle’s course and minimize an accident.
What Is VSC Light Indicated?
The VSC is responsible for creating friction for your 350 Lexus. The VSC regulates the vehicle’s inbuilt traction control system.
Traction control assists the vehicle in maintaining a stable grip by lowering engine power transmitted to the four wheels.
In some cases, it applies braking force via the anti-lock brake system. Thus, the system remains gripped when driving on wet or unsteady streets, which might cause a loss of traction.
Drivers will have improved steering control to help them navigate tough roadways.
Every car has wheel speed sensors interacting directly with the Lexus engine control unit (ECU). So, what is lexus check vsc meaning?
The traction light or check VSC Lexus es 350 Warning will occur when something is wrong with the process.
It signals when the traction control system is malfunctioning. Besides, it may also display if you accidentally hit the VSC button.
What Does Check VSC Mean On Lexus es350?
VSC interacts with an anti-lock braking system. If you notice the VSC OFF alert light on the panel, it signifies your traction control is entirely off and will not operate when you lose control.
If you own newer versions of Lexus or Toyota, including Lexus es350, you may notice a message to check the VSC system together with the check VSC light.
What Commonly Cause The Message Of Check VSC On Lexus?
There are several things that can go wrong. It is because the VSC system is connected with brake control mechanisms and engine management to regulate your vehicle’s grip.
Here is an extensive summary of the most likely reasons for the VSC flashing light as follows:
Engine Issues
The most typical cause of the VSC signal being illuminated is because of an engine problem.
It’s particularly true when your panel displays a Check Engine light and additional lights of the VSC.
Newer engines feature several actuators, sensors, and other components that might cause a check light.
In case you own a Lexus or Toyota, it will be an additional check VSC light. As a result, guessing what triggers it seems impossible.
A fault code is saved in your engine control unit whenever the VSC lights and check engine activate on the instrument panel. You should read this issue code to determine what triggers the warning lights.
A few prevalent engine problems that might result in a VSC signal are:
- Poor O2 Sensor
- The gas Cap Is Loose
- Defective MAF Sensor
- Wiring Problems
- Bad Accelerator Pedal
- A defective Crankshaft position sensor
However, Other parts might cause these issues. Thus, it’s necessary to examine the codes using a scanner.
Faulty ABS Sensor
ABS speed sensors are positioned on every vehicle wheel to detect the engine speed. The ABS module and other critical control modules like TCM and the ECM use this data.
Such ABS sensors are situated on the wheel hubs and therefore surrounded by dirt, corrosion, and water. They can all put them at risk of failure.
Since the VSC system relies on this data, a VSC 2007 lexus es 350 check engine light will be illuminated when the ABS sensor fails.
It is also likely to be an issue with the ABS rings used by the sensors to detect speed. It might be a connection issue between the ABS control module and sensors.
Furthermore, the VSC and ABS systems use the steering angle sensor. So, when it sends the incorrect output to these two control modules, the VSC light and abs light will illuminate.
Faulty Brake Light Switch
You can find the brake light switch on the brake pedal. People sometimes call it the brake pedal switch. Its purpose is to turn on the brake light when you hit the brake pedal.
Also, its second function is to send information to several control modules after you hit the pedal.
One system that needs to use this data is the Lexus check VSC engine light system. As a result, whenever the brake pedal switch has an issue, you will see the check VSC on Lexus.
Wiring Issues
Newer models of Lexus cars like check vsc 2007 lexus es350 feature many electronics that require wiring. It is the main reason there are a lot of common wiring issues on modern vehicle versions.
One of the bad things about the wiring problem is the intricacy. It is rather hard to inspect the problem location unless you have good mechanic knowledge and skills.
Thus, when you have checked everything else and find no problem, it is time to talk to a qualified professional to examine the wiring.
Pushed VSC Button By Mistake
If you use a car that comes with a VSC system, it is possible that it features a switch to turn off the system.
During your car journey, you may accidentally press the button, which will make the VSC light displayed on the dashboard.
Therefore, it is advisable to double-check it before you make any consumption. In some cars, the VSC light will still be off in place of a normal VSC light when the button is hit.
However, you should check it beforehand as you may also set the caution lights off with the button.
How To Fix VSC Light On Lexus?
There are many ways to fix the VSC light, but you’d better use a scanner to read the trouble codes and locate the problem.
It will be much easier when you figure out what causes the issue. You can also look at the brake fluid level and brake lights. Here are the details.
Read Trouble Codes
Due to the wide range of issues that might result in a VSC light, you should carefully check the faulty codes from the ABS, engine, and other relevant control modules in advance.
Today vehicles feature powerful troubleshooting technology that may detect and report an issue with an ABS sensor or an engine sensor.
That’s a great thing since you won’t have to check and analyze each sensor in the automobile.
An OBD2 scanner will read the information for you when something goes wrong. You can read the fault codes using a less costly scanner.
When you can’t detect a fault in the engine control module, you can visit an auto repair service, and the code reader will do the job for you.
Check Brake Lights
A typical component that might trigger the VSC light to activate is the brake pedal switch. Thus, inspecting the brake lights is a simple and quick remedy.
While you examine the brake lights, ask a family member or a friend to push the pedal with your engine on.
Sadly, several brake pedal switches have two distinct currents, and even though the brake lights function, the switch may be faulty.
However, it is good to inspect the brake pedal switch if your automobile doesn’t have any brake lights when operating.
Check Gas Cap
A leaky or faulty gas cap is a typical source of a 2009 Lexus es 350 VSC check engine light, especially when combined with a check engine light and TRAC OFF light.
Suppose the VSC light is turned on after you refilled the gas to your automobile; ensure the gas cap is correctly secured.
The problem can also happen when you leave the car operating while refilling. If this is the case, merely emptying the code memory will be sufficient to resolve the VSC light.
However, it would help if you examined the O-ring of the gas cap to ensure that it is not leaking and correctly sealing.
Check Brake Fluid Level
Looking at the brake fluid level is another easy repair method. Low braking fluid can trigger various issues with the anti-lock brake system, including the faulty vehicle stability control system.
As a result, you should inspect the brake fluid tank to ensure that the level is enough. If it is dry, look for any brake fluid leakages from all over the brakes, then replenish the reservoir.
