Which relays and where are they situated do i need to check for engine management problems

OK, because the check engine light is on you need to get this looked at as soon as you can. VSC stands for 'Vehicle Stability Control'. It is a safety system that works through your Brakes so Get It Repaired to be safe driving!!
VSC is designed to help control your vehicle to stop it spinning or sliding out when cornering. Times like driving on icy, rain soaked roads or simply too fast into a corner. This could be anything from a blown fuse, a faulty wheel sensor or even an problem with your actual brakes.

Mike here may I give you a suggestion just remember any yellow light on means poor performance red light is danger resetting it is ok and if it comes back on take it to a autoparts and they will code it out for free use maybe Autzone or Advance do not pay a high price shop Good Luck Mike

vehicle stability control and traction control work together so if one turns on the other usually turns on at the same time, the fact the engine light turned on as well makes me think it could be a voltage issue. possibly weak battery. tsc and trc are very sensitive to voltage changes and so are emission control on the engine. so in theory the low voltage would cause all three light to turn on. a generic drb2 would be able to scan the engine light code, so if it has anything pertaining to voltage I am sure that would be your problem

Has to be diagnosed at a repair shop

Surely you don't think someone without
the vehicle to test ,can guess at what is
wrong with it

Hello, the skid control/trac lights will turn on when the check engine light turns on, they usually go off when the check engine light malfunction is fixed first. There are some diagnostic codes in the engine control module, if you live in the US you can go to any one of the national autoparts stores and they can get the codes from the computer for you, they will also give you a recommendation as to what the problem may be, if you have any questions after that just reply to me and I'll be glad to give you my opinion

When your VSC (Vehicle Stability Control) light comes on, it means your car has been forced to take evasive action to avoid a dangerous situation. For example, if you're driving on an icy or wet, slippery road, and take a turn too sharp or accelerate too quickly, the vehicle will automatically reduce acceleration or apply pressure to the brakes to prevent the car from losing control. In this situation the VSC indicator light will light up to alert you that the action was taken, and remind you to slow down - or to be extra careful. Be safe!

TAKE IT TO DEALER.TO SCAN AND CHECK THE VECHICLE SKID CONTROL ECU.

tow it to shop.deer did some major damage.its not a home fix. i hit a deer back in december.it cost me $2500.00 in damages.

I also have a 2002 Sequoia, mine with 100,00o miles and replaced breaks in the spring. My VCS and brake lights also were coming on, and baffled as to why. Someone told me to have my break fluid checked, I did and it was low, once they filled it and moved my car the break light went out but the VCS lights were still on, part problem solved. I ran a quick errand turned my truck off, when I returned and turned it on the lights were off. I am hoping that by putting the brake fluid in , solved my problem, so far so good. Hope this helps you as it did me.
