Check engine light and vsc track off light is on.
Why are the lights on
My car has 177000 miles.
Experienced mechanics share their insights in answering this question :
Hi there. The vsc track off light (traction control light) is on for the computer has turned off the traction control for something stopped working. Check the wheel speed sensors and the wiring to them. A dirty wheel speed sensor can cause the traction control system to disengage as it cannot register anything with the computer. The check engine light is on for the computer has stored a code for the issue that is happening. If you need further assistance with the warning lights, then seek out a professional, such as one from Your Mechanic, to help you.

What causes check engine and VSC lights to come on? Either a worn-out cap or one that was put improperly. The car is instructed to switch on the check engine light and turn off the traction and VSC by the C1201 code. In essence, this code is responsible for alerting you to an issue when the other two appear.
VSC System OFF and Check Engine Light is On
VSC stands for “Vehicle Stability Control.” It is likely that “Traction Control” will not work while this light is illuminated. On some vehicles, the “skidding vehicle” or “TRAC OFF” light may also be lit as well.
If both front wheels get stuck in fresh snow or mud, you may need to turn off both Traction Control (also know as TRAC) and Vehicle Stability Control (VSC) so you can rock the vehicle to free it. To turn TRAC off, simply push and release the VSC …
The traction-control light is usually a sign that your vehicle is working properly by maintaining traction on a slippery road, but it can also mean that your car has some damaged sensors or wires. Keep yourself safe on the road by taking your vehicle to a trusted auto repair shop at the first sign of trouble.
What does VSC mean? VSC is short for `Vehicle Stability Control,` which is the stability control system that Toyota uses in their vehicles. Stability control helps your vehicle maintain traction and control by reducing—or completely cutting—power sent to your wheels.
“VSC Off” and “VSC TRAC” lights will often come on when an error code triggers the Check Engine light. It doesn`t necessarily mean there is an issue with those systems. If they all showed up at the same time, it`s likely that diagnosing the cause for the Check Engine light will fix them all.
All that`s required to turn it back on is to push the switch. The vehicle stability control frequently deactivates when the traction control system is manually turned off. The VSC light might also be displayed on the dashboard, along with a graphic of a car sliding on the road and the words “OFF.”
Once you see the check engine light, it is safe to drive with the light on for 50 to 100 miles. This is because if the issue is with the sensors, then this will buy some time for it to reset, turning the check engine light off.
A-TRAC Indicator Light
Indicates that the Active Traction Control (A-TRAC) system has been activated. The Active Traction Control system automatically helps prevent the spinning of four wheels when the vehicle is started or accelerated on slippery road surfaces.
In some vehicles it is located under the hood and/or is a part of the ABS control module. Other vehicles may have the traction control module located in the interior or trunk areas.
If the traction control light won`t turn off, there can be some reasons. One reason could be that the fuse for the traction control system has blown. Or it could be that there is a problem with the traction control sensors causing the light to stay on.
It could be a faulty Speed sensor which is located on the wheel calliper area. A bad steering rack could also be a problem so it is important that your mechanic checks the VSC and ABS components when you see a VSC light on. In some cases, the light comes on because it needs reprogramming.
The cost to replace the engine was estimated to be about $5,500 to $6,000. The radiator is additional. If the motor hadn`t fried, it would have probably cost about $2,000 to get the car running properly again.
If the system indicates your tires may be slipping, the slip indicator flashes to indicate that Vehicle Stability Control (VSC) and/or Traction Control (TRAC) are operating in order to regain traction. If the light stays on, it could indicate a malfunction in the TRAC/VSC system itself.
Simply push and release the VSC Off button located near your gear shift, and your TRAC will be turned off. Look for the TRAC OFF indicator light near your speedometer. Your VSC Off indicator light will be here as well. When you want to turn the TRAC back on, just push the button again.
TCS – As the car picks up speed from idle on icy, snowy, rainy road conditions and the tyre starts to spin, TCS kicks in to ensure the contact between the wheel and the road by reducing the speed of the wheel. VSC – This system kicks in when the car loses traction while cornering.
While your car is typically safe to drive with the traction control light on, you should not drive it under certain conditions. If the traction control light, anti-lock braking system light, and red brake-warning light illuminate, your entire braking system may be affected.
In some cases, the warning light may come on because wheel-speed sensors are covered with road grime or debris. When the traction control warning light stays on, that means you aren`t getting any help from the system to control traction and the system needs to be checked.
So why is the light still on? Here`s something you probably don`t know: after clearing the car`s computer you will need to drive for about 50 to 100 miles. As you drive your car the computer will monitor all the sensors and register the results.
To make sure the check engine light does not reappear, it`s recommended that you drive your car 30 to 100 miles. This enables the vehicle`s “Drive Cycle” to reset, as the various sensors need time to recalibrate.
So how do you know when you have an emergency? You can judge how serious an issue is by looking at the warning light. The check engine light can show up in two ways: Solid yellow/amber light: Indicates a less urgent issue. Flashing light or red: Indicates a severe problem that needs immediate attention.
Will the check engine light reset itself? The check engine light on your Toyota will usually shut itself off if the issue or code that caused it to turn on is fixed. For example, if the cause of your check engine light coming on was a loose gas cap, if it`s tightened, the light will turn itself off.
Sometimes, the check engine light comes on to let you know that there`s a problem with the car`s internal diagnostic mechanism. That means the system could be “finding” a problem that doesn`t exist, or it could be that loose wire systems are creating a false positive in the system.
Problems with sensors responding
Another common sensor problem is between the electrical connections from the sensor to the computer. If the connection is disrupted, it leaves the traction control system vulnerable to error. And that impacts the drivability of your car.
