I’m new here so bear with me. Started truck this morning and noticed the VSC OFF light is on on dash. Is this normal? I can hit a switch on dash to turn lite on/off. Now I’m not sure if light should be on all time. Help?!

If the lite should be off that means the VSC is on all the time, correct? Doesn’t that affect gas mileage if VSC is always on?

VSC is always on until you hit the button which then means you turned it off. It stands for vehicle stability control and it in no way affects mileage. Its a passive computer controlled system that helps in the event that your vehicle starts to get in a slide and it works by applying brakes to specific wheels to reduce or stop the slide. Passive meaning it doesnt actually do anything unless its needed. Driving with it off just means that in the event of a slide you would be on your own to correct it, basically like old school. Google it to get a better understanding if you want.

Cheapskate, thanks so much for the explanation on VSC. Weirdest thing happened today; as I was leaving auto parts store, started truck & noticed VSC & traction dash lites came on & blinking. I turned truck off & restarted, same thing. Drove home(maybe a mile), turned truck off & back on, everything looked normal. Have not had it occur again(yet!) but don’t know what caused it. I did have brakes serviced(rotors turned) several days ago. Could that have had an effect? Anyway thanks again!

That sounds more like you are throwing some sort of code. Not necessarily a huge deal but you could go to your local auto parts store and see if they will check it for free as most will. If someone hit one of the ABS wires around one of your wheels, yes, possible it could have done it but could also just be coincidence. The only way to know for sure is get it read and make sure you get the actual fault code, if there is one. If you do get a code number you can google search it or search it on here.

Will do. Thanks again!

No to which??
Fuel mileage effects. As was pointed out, VSC is normally on.

There is a spreadsheet on the site that will help diagnose issues by what lights are on or flashing. Or, as cheapskate said, parts stores will often read the codes for free.

When this started to happen to me it just got worst. Heard brake rotor rubbing backing plate then it wore away the plate. Long story short my rear wheel bearings went bad, and it leaked oil on the speed sensor. That made the sensor not work then a bunch of lights come on the dash. $1500 later it was fixed new plates rotors and bearings.

You may need to clean the magnetic anti-skid sensors on each wheel as well as make sure the connections are tight...it sounds like an intermittent problem or may be an indication of an impending sensor fail. I had a similar anti-skid issue on my 06 Tundra and ended up replacing a sensor to fix it.

Hello good evening if your VSC LIGHT WITHOUT THE LITTLE CAR WITH THE SQUIGGLY LINES ON IT AND THE CHECK ENGINE LIGHT IS OFF. It will be your speed sensors. It could be one or two, but I would replace h Th hem all.
if all the lights are on, it will be your air pump valves. How many miles? What engine is it?
