2001 rx300-- the "vsc" light on my dash is on..
Is you VSC light on by itself, or is it on with a Check Engine Light as well. If it is just the VSC light then you need a Zero-Point calibration. This is supposed to be only done at a toyota/lexus dealer. They take out the VSC computer and run their diagnostics program and reset and configure(calibrate) your vehicles VSC. I personally would disconnect both battery terminals for at least an hour, even better overnight, this should allow enough time to have all the electricity drain completely from those computers. Hopefully this would reset everything. I would try this before going to the dealer, try to save some money. If it is the VSC and CEL(Check Engine Light), then you would have to get the codes read at AutoZone....they do this for free unlike the dealer and then post your codes up on this forum. Hope this helps.
The code that I'm receiving with the VSC light and Check engine light on together is p1135. I've checked all hoses and changed the 02 sensor, bank 1 sensor 1. had the codes erased and they still come back, what else could it be?
check the vacuum hoses on the back side of your air cleaner on the firewall side you will need a flashlight to see them. most likely they came loose when someone either checked or changed your air filter look for a metal tube coming up it should go into a rubber hose
I have had the same problem (VSC and Check Engine, Track off - light on). The OBD read by autozone was 1135. I drove like that for one month. Today, I decided to fix it. I checked the the vacuum hole/metal tube behind air filter, which was fine. Then, I changed 2 air fuel ratio sensor (B1S1 and B2S1, Bosch part number 15217, $180 each) and reset computer by unhooked positive battery terminal for over 10 minutes. The problem is fixed. VSC, CE, and Track light is off. Note that the front B1S1 is easily replaced in 10 minutes, but B2S1 must be accessed from the bottom of car and take over 30 minutes to replace. The wrench is 7/8 english size. See photo by other poster.
I have the same problem. My VSC and check engine lights have been on for years now. My Rx 330 has 225000 miles. The dealer says my VSC cable on one of the wheels is severed and this is causing the problem. I never checked into the cost of repairing it.
hey thanks for answering, my dad ended having to replace a couple of the sensors and it went back to normal
hmmmm how much were the sensors and since your dad did it is it that difficult. I am a Dad maybe I can do it as well :) hahaha
We have a 2001 RX300 and have been having VSC, CEL and Track off problems for a long time. We spent $1800 to have all the O2 sensors changed, everything seemed ok. Then came winter, when it rained the VSC light came back on. (I am so tired of repairing his car) I forgot to mention we just spent $3000 on a new transmission during last summer (115000 miles) Anyway back to the VSC, here is my fix (1) remove negative battery terminal for approx 10 min or (2) remove the yellow 25 amp fuse for approx 1 minute. Both of these will clear the computer and reset, VSC light goes off, or at least until the next rain. This occurs because one of the wheel sensors is dirty or malfunctioning which sets off the VSC light. This is not a long term fix but at this point it works short term. Here's another fun lexus oddity, now that winter is here our windshield defrost stopped working, no matter what button you select, it only blows face level. If I push defrost (auto or manual) still just blows at face level. Once again I removed negative battery cable for 10 minutes, and walla defroster now works. Some weird s**t going on with the RX300. Good luck. Wait until you try to replace the spark plugs (120000 miles)
I disconnected the battery and the light has gone off, The car has been to a garage 5 times to get this sorted and they failed as the light came back on soon after getting it back (annoying) So THANKS all x Sue
Disconnected the negative battery cable for 10 minutes and "voila" the check light is off! Thank you!!!
fault code P0505 was the reason the VSC & engine management lights kept coming on. The valve was seized.
How do I disconnect the battery cables that you guys are talking about? I'm a Mom and have no clue. Is this something I can do on my own? Is it pretty easy?
mom you need an adjustable open wrench fit it to the nut of the battery and turn it counter clockwise until the battery terminal is loose lift up wrap a rug around it to make sure it does not touch any metal part and wait for whatever time and reverse the procedure.
I found out after reading some answers that hoses were not connected after wallmart replace the air filter. looking directly after the air filter one hose leading to a metal tube was disconnected and an elbow type tube was not into placed {behind the air filter] into the filter assy SHODY WALLMART WKMANSHIP it can cot you $$$$$$
I had the sensor replaced and it wasn't that so had the valve unit cleaned out and they found the valve was seized, they managed to get it cleaned up and got the valve working (thankfully) as a new valve unit would have cost over £300.00. The car now runs a lot better,,, revs have dropped and the fuel economy is very much improved. The cost of having this sorted out was £100.00.
