What to do when your TCS warning light comes on?
If the TCS and the ABS warning lights both come on, along with the red main brake warning light, you should not drive the car until the problem has been fixed. Your entire braking system is affected, and may not be able to stop your vehicle when you need it to.
What to do when your traction control warning light comes on?
If a fluke in the TCS system triggered the warning light, it should turn stay off when you restart the engine. If it comes back on, it’s likely time to call a mechanic and get a system diagnosis. Until it’s fixed, drive gently and avoid hard acceleration that could result in the wheels slipping.
When does the Check Engine light come on?
Recently the check engine light, the vehicle stability control light and the traction control system light all came on simultaneously. Since then they have all come on or all gone off several times. Usually once they come on, they stay on for the remainder of the trip.
Why are the VSC and TCS lights lit up?
The reason why the VSC & TCS lights are lit up is because the engine must be working at its optimum in order for those systems to work properly. When everything is not working at its optimum, the VSC & TCS are shut down–thus the warning lights.
If the TCS and the ABS warning lights both come on, along with the red main brake warning light, you should not drive the car until the problem has been fixed. Your entire braking system is affected, and may not be able to stop your vehicle when you need it to.
Where is the app sensor on a car?
The APP sensor is found in almost every vehicle today. This is a component of the Drive-By-Wire system, which does away with the throttle cable. In a DBW system, the ECM receives an input from the APP sensor and then commands the appropriate throttle opening using a throttle actuator motor.
Where is the accelerator pedal position sensor located?
Describes the operation of the APP or accelerator position sensor. The APP sensor is found in almost every vehicle today. This is a component of the Drive-By-Wire system, which does away with the throttle cable.
What does the computer do on a Cadillac?
A Cadillac’s computer controls the emissions system and other vital systems on the vehicle. When there is something wrong with the Cadillac, the computer will generate and store a fault code. You’ll need to run a diagnostic test to figure out what is wrong with the vehicle.
When does the traction control light go off?
When the road conditions improve your traction control system light should go off. Sometimes the Anti-lock Braking System and the Traction Control System share the same internal diagnostics system and control module.
What does it mean when the TC Lights Come On?
Thus, if there is an issue with the ABS system the TC lights might come on to indicate a problem. If this is the case, you will have to get the ABS system checked out by a mechanic.
Why does my car have a reduced power warning?

What does it mean when your check engine light is on?
If the light is steadily lit, that means that one of your engine sensors picked up suspicious reading. This can indicate a problem with an engine component, or with one of the sensors. You can still drive with the light illuminated, but you should get it checked out as soon as possible.
How does the traction control system ( TCS ) work?
A reduction of engine speed may also be utilized to assist drivers in maintaining control over the vehicle. The traction control system (TCS) is made up of wheel speed sensors, solenoids, an electric pump, and a high pressure accumulator. The wheel speed sensors monitor the rotational speed of each wheel.
