Question about 2002 Toyota Highlander

2 Answers

Check engine, VSC and Trak off lights came on today. 2002 T. High

The aforementioned lights came on today on my 2002 Toyota Highlander Limited. The owner's manual advises to see the T dealer . . . and I prob am. Howeversome and then some, I am reluctant to take it to the dealer and be at their mercy. Are these lights indicative of something serious and, more importantly, am I looking at a major expense . . . which I can hardly afford at this time. Is this something that a non-Toyota shop can diagnosis and make needed repairs? Thanks for any suggestions and/or advice.

    Thanks. As to the two lights being on, I assume that you referring to the Trac off and VSC lights. They are both on. The check engine light is also on. What's up with that? Thanks, Deelie

    Thanks for your advice. I will take it to my Toyota dealer. Although I know what ABS stands for, I'm not exactly sure about ECM. Electronic something Module? Any guess on what my costs could be? Worst case?
    Thanks again, Deelie

These lights can only be shut off by scanner. If Both lights are on, there is a fault in either the ECM or the ABS system. It will have to be tested. You can go to a non-dealer mechanic to have this serviced, as long as they have the correct test equipment.

    There is a fault in either the ECM or ABS which is also triggering a fault code in the computer and that is why the check engine light is also on.

    ECM is an electronic control module that is the "brain" of the ABS system. It could be $250-400 for replacement. Most cars I have worked on price in this range.

I think that it may be a wheel bearing. i once had a 2000 pontiac grand am where i had the same problem. the problem lies in the electrical connector that is mounted on the wheel bearing. when it got replaced, the check engine light came off as did the trac light

My toyota highlander 2002 VSC light is on. i dont know what the problem is. Pls assist.


VSC is vehicle stability control, there is a switch to turn this option on and off, it could have been bumped, or a wheel speed sensor could be bad, if that is the case you will soon have an ABS light as well and most likely a traction control light

2001 toyota avalon engine and vsc light stays on


You have to use a scanner and pull the code out that is causing the check engine light to come on. whatever code/codes you find are probably related to vsc light.
Good luck and keep me posted

2005 Toyota Highlander check engine, track off and vsc light on, what is the problem


there are literally hundreds of codes that would turn on the check engine light. the track off and vsc lights come on together, indicating a problem with the traction control system. again, many different items will turn these lights on. the only way to narrow it down is to hook it up to an OBD-II diagnostic tool and find out all the codes that are listed. if you don't have one, take it to a shop
