Friday after work I started the car in a sheltered car garage and as soon as I started the car the after the initial start up sequence the check engine light stayed on and the traction control (ETS) light stayed on and right next to it on the left side the "VSC Off" light kept blinking and flashing. I turned off the car and started it several times to see if that did anything and to no avail nothing happened. While I was driving those lights stayed on and the VSC off light kept on blinking. I also checked the brakes and the brake fluid and they all seem to be fine, I even checked the gas cap and fuel door as well, also I checked the air filter, the MAFS the intake box, the Vacuum hoses, also used a fuel injector cleaner to see if the problem was caused with a dirty injector, but the light stayed on and blinked constantly. I am not sure what is wrong. I was looking at some of the complaint sites and most people say it happens when you drive through a deep puddle or if it is cold and wet outside. But that didn't make sense because I drove in the snow and those lights never turned on. The only time I used the ETS button is during the snow storms and I drive at low speeds. Also when those customers went to the dealership and had it checked out the dealership told them that it was because the gas cap wasn't tightly shut but even after that the customer's ETS light, check engine light and "vsc off" light kept lighting up. I need to know why this VSC off light is blinking? Is it a bad sensor or is the ABS/ETS brake system broken or is it an ECU issue or is it because of an alignment. Also is it the cabin air filter because I didn't replace it and it was pretty dirty when the technician at Toyota showed me. Since I was told to get an alignment soon. I just got the oil change, the 50 point visual inspection, tire rotation, and wiper blade insert replacement back on thursday February 24,2011 and the technician told me that everything was checked out ok except for the dirty cabin air filer

Really, you need to scan the car for codes, as there are several hundred. The VCS and ETS are all part of the same system, that being the power train control. Since you have an ETS light which is a malfunction with the electronic throttle control, then you will get a check engine and a VSC light as well as they are all dependent on a properly working electronic throttle system. Again, get all the real codes, not a parts store quickie scan and then deal with the problem. Remember, Toyota has had problems with their throttle systems, I have never seen an accidental, unwanted acceleration, but I have seen pedal and throttle position sensor codes several times with theses systems.

I also have the same problem with my 2010 corolla. Happened at 54090 miles this evening. I think this is a common issue with Toyota 2010 model.

My 2010 Corolla did the same thing. I had it towed to the Toyota dealership because began to jerk when excellerated. They checked it out and said it was the VSC sensor that was bad and had to be replaced. Quite costly. I have had more repairs on this Toyota than any other Toyota I have owned.

Get your car to a Toyota dealer and ask them to repair it. It should be covered under warranty. Without proper diagnostic no one can really help you since those lights could be on for hundreds of different reasons. Yes, one could be an ABS wheel speed sensor. Zee

My passenger compartment was wet when running the air conditioner. Then my dash lights came on flashing and the check engine light . Cleared the condensation line on the passengers side behind the carpet. It was plugged and gushed water until I blew out the lower line. I removed the negative battery terminal for 30 seconds and all the dash lights went back to normal.
