The Track Off light, Brake light, ABS light and the VCS light always stays on in my 2002 Toyota Sequoia. What could be the problem?

Answers from the Automotive Experts

Amanda J. Pierce, MBA Paul, At times a faulty YAW sensor, may cause all of those lights to come on. The YAW sensor detects turning of the vehicle, almost like a compass. for example, in a skid you will conunter steer and the yawl sensor will detect turning one way while you steer the opposite and the car will activate your abs as it needs to. Yaw sensors are usually frame mounted and hidden. I suggest having this inspected for fault.

Amy Mattinat, Owner and Author at Auto Craftsmen Ltd They are all connected to the problem. Whatever is wrong causes the computer to turn off all these features for safety reasons. The technician can used the stored codes in the computer to help diagnose the problem.

Barb Petrey, President - DBK Enterprises Inc at Jiffy Lube They are supposed to be on. So they show you that it's working.

Gelina Aquilina, Service Advisor / Mechanic at It could be an electrical issue or you could actually have issues with those systems.

Helaine Kurot, Owner/Technician at 360 Automotive Is the check engine light on also? (Does the check engine light work)? With the exception of the brake light, these lights may come on depending on what code is set as theses systems are all connected. How is the brake fluid level? The brake light coming on will potentially disable the abs and traction control systems. There may also be a Battery/Charging issue as this will also cause the dash to light up like a Christmas tree. Get it looked at by a trained technician, as you are dealing with systems that have a direct affect on systems that are designed to keep you safer when road conditions are less than ideal.

Maryann Croce, Owner at Croce’s Transmission Specialists Hi Paul, On your 2002 Toyota Sequoia, I would recommend getting your vehicle scanned for a diagnosis. There could be only one issue that is making all of the lights you mentioned stay on. If multiple codes are present a shop may record them and then clear them and then drive the vehicle to see which code or codes come back to address your issue. Good luck.
