Question about 2002 Toyota Highlander

1 Answer

Check engine and svc light came on Toyota Highlander 2002

I was driving down my road and looked down and noticed the two lights had come on. I have noticed nothing different about the way the car drives. Smooth and quiet with good acceleration. I had this happen once before a few months ago and the mechanic said it was a hose that had loosened. It is just now at 45k miles, and the only thing I could think is that it's about 120 miles past the oil change mileage.
Any input here? I checked my gas cap removed and re-tightened it, but the lights still stayed on. It just finished being under warranty...ofcourse!
Help!!

Have the history codes read. This will give you an idea where the problem is. Anytime the light comes on, it is stored in the ECM. If the light goes off, then it is stored in the history codes..

What causes a toyota highlander VCS warning


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!

2002 Toyota highlander passenger brake light not working


RE: 2002 Toyota Highlander 2.4cyl. 4X4 Base Model

I am a Certified Technician and have basic knowledge with electronics in electrical wiring. I searched the web and discovered this is a common problem.

I fixed the problem and it was a simple procedure... The problem is with the reverse light socket at the side with no brake light. This socket functions as a hub to direct current to the brake bulbs.

Remove reverse light socket and re-seat bulb. Check for loose or broken prongs. Replace if necessary.

Swap the reverse socket with the other side.
