01 3.4L 4Runner, 'VSC Off', 'VSC TRAC' and 'ABS' lights coming on intermitantlyChad82 03-25-2007, 06:53 PM For the last week or so, those 3 lights have been coming on and off randomly. Most of the time if it comes on, it will stay on until I shut it off, but twice they have been on and then shut off after a little bit. Since they all appear to have the fuses stored in the same box over the passenger side wheel well, I am assuming that it is either a bad wire or poor connection. I will try to check them both next weekend, but could you think of anything else it might be? Chad82 04-19-2007, 04:45 PM So I checked all the connections I could, checked fuses, picked up an OBDII scanner (been meaning to for some time) and everything is clear. I'm thinking maybe I should check my brakes? Been a while since I have and in my old Q45 when the pads would get thin it would send out messages because of scanner. Brian R. 04-19-2007, 08:44 PM Just guessing: Are all your tires the same diameter? Like is one or two of them have alot less or more tread than the others? Might be a bad ABS sensor or sensor wiring. Chad82 04-20-2007, 02:51 PM The tread on all the tires is similar just eyeballing it, but it has been about 10k miles since they've been rotated. When I check my brakes I will also check the sensors, thanks for the idea. Brian R. 04-20-2007, 03:38 PM Tire pressure, if it's really different in one tire may have this effect also. Chad82 04-21-2007, 04:00 PM tire pressure was fine, right rear was 1 under, doesnt seem like that would be significant enough. Front pads are getting thin, though, so I will go ahead and do them next weekend. Chad82 07-04-2007, 11:22 PM So in case anyone else ever has this problem, it was a bad front left speed sensor. vBulletin®, Copyright ©2009, Jelsoft Enterprises Ltd.
