"The Slip Indicator Light Problems on 2004 Toyota Highlander"

Silver 2004 Toyota Highlander Left Front View

On my 2004 Toyota Highlander the slip indicator light flashes when the speed reaches >20 mph or so and I can’t drive any faster, it feels like the brakes are holding the car back. Only the slip indicator light is lit on the dashboard. The dealer says it is a $2700 repair but I find that hard to believe. Please help.

Answer: If the light is flashing, either the traction control or the stability control system is operating. It THINKS it is working normally, so it is very possible that there is a ring loose or cracked, or a problem in a sensor as has been noted. If it is a 2WD model, just turn the system off with the TRAC OFF button located by your right knee. If it is 4WD, there is no switch. For $2700, they obviously think the problem is in the ABS/VSC/TRAC pump/module, and are recommending replacement. If that is true, then the real question comes down to, “Is it worth $2700 for that system to work?” If the answer is no, just disconnect the unit. It is located on the right fender behind the headlight, and it will have a bunch of metal brake lines running to it. If you can get it disconnected, it won’t work, but the brakes will work normally (WITHOUT ABS, VSC OR TRAC!)
Also, if there is a buzzer that goes off at the same time the VSC light comes on, there is a TSB on that condition and you may need to bring it to the dealer’s attention, as it is not that expensive a repair.
