Toyota kluger 1007 how to remedy vsc light on. vsc not on


Not sure if this will help, but my 2002 LEXUS sc430 had this issue, and it turns out that if you plug any scan tool other than the dealer unit in, it will cause this VSC lights to come on. It requires that you reset the "zero point calibration" for the skid system, which is done by first: have car on level ground with less than 1% slope in any direction. Next, follow these directions:

If you receive the "VSC" and "VSC Off" lights on the dashboard after a visit to a mechanic (often an independent mechanic using non-Lexus ODBII equipment), this means your "Zero Point Calibration" has been erroneously reset by a non-Lexus specific ODBII tool. This might especially happen if your state requires state inspection via ODBII, and you take your Lexus to a no-name place (like a Jiffy Lube or something). Follow the steps described in Post #6 in this thread to resolve this issue:
http://www.clublexus.com/forums/gs-2...d-vsc-off.html
Note that where you see a reference to a tool called the "SST 09843--18040", substitute that "tool" for a simple jumper cable (such as a short speaker wire) or a paperclip.
Here is the relevant excerpt from the above thread:
"The solution consists of approximately 15 step .
NOTE:While performing the Zero Point Calibration, do not tilt, move or shake the vehicle.
The vehicle must remain in a stationary condition throughout the entire process.
Be sure to perform the procedure on a level surface with an inclination of less than 1%.
Explanation of symbols:
SST (4-inch wire)
DLC3 (OBD-II connector under the dash)
TS (on the top row,pin number 3)
CG (on the bottom row,pin number 5)
(See picture below)
1. Ensure the shift lever is in the ''P'' range.
2. Turn the ignition switch Off.
3. Using SST 09843--18040, repeat a cycle of short and open between terminals Ts and
CG of DLC3 4 times or more within 8 seconds (refer to the specific vehicle EWD for
TS and CG pin location in the DLC3).
4. Turn the ignition switch ON, do not start.
5. Verify that the VSC indicator light is lit indicating the recorded zero point is erased.
6. Turn the ignition switch OFF.
7. Be sure the terminals Ts and CG of DLC3 are disconnected.
8. Turn the ignition switch ON, do not start.
9. Check that the VSC warning light goes off about 15 seconds after the ignition switch
is turned ON.
10. After ensuring that the VSC warning light remains OFF for 2 seconds, turn the ignition
switch OFF.
11. Connect terminals Ts and CG of DLC3 using SST 09843--18040.
12. Turn the ignition switch ON, do not start.
13. After turning the ignition switch ON, check that the VSC warning light is lit for about
4 seconds and then starts quick blinking at 0.13 second intervals.
14. After ensuring the blinking of the VSC warning light for 2 seconds, turn the ignition
switch OFF.
15. Remove the SST from terminals Ts and CG of DLC3.
16. Drive the vehicle for at least 5 minutes to confirm Zero Point Calibration is complete."

How can one disable (or turn off) the VSC traction control while on 2WD mode so that one can do a Smog Check?


The smog center should know what to do, call the air resources board and ask for help getting it smogged. I am a former smog tech from calif and i know thios for sure.

Check engine light and vsc trac off lights stay on. Cannot turn svc off by pressing button on Dash


Hi, have you scanned the vehicle to see why your check engine light is on? IF no, you need to. Toyota/Lexus computer system illumniates both engine light and VSC lights whenver a fault occurs in either unit. VSC or stability control is like trac-control or ABS braking system. Get car scanned and make sure all computers are scanned for additional codes, repair them first reset lights and test drive. ON a side note, fixing check engine light will usually take VSC light away also, however sometimes the VSC system will glitch out and a Steering Angle relearn is necessary, it takes about 3mins to perform and a good quality scan tool with 2004 current software. Good Luck.

Why the vsc light comes on?


there is a fault in the VSC (vehicle stability control) system, have the dealer test the system for the fault code that is stored when the light is turned on.

What does the VSC light on the dash mean


VSC means Vehicle Stability Control. Take the car for a scan to ease your mind.

TRAC LIGHT ISSUE


The trac light does NOT come on for the smog test. It has noting to do with the smog test. The trac light DOES come on when the Check Engine light comes on, when a failure is detected. From what I remember, the trac light WILL come on if the smog is a "dyno-driven" smog test, but it has nothing to do with the test, the trac simply comes on because only one wheel is spinning, just like it will when you are spinning on ice.. Hope this helps.

Check engine and VSC lights on


I talked to you on the live chat, and I think that you may have missed the end of my typing...

What I went on to say is that more often than not, on the 02 4Runners, the Check and VSC lights in tandem look mainly after the emission system, and, since you stated no issues during the road test, I would guess that it is a fuel issue (too full/loose gas cap). But, if you can get the vehicle scanned, I will be very glad to provide you with more and better info if you provide me with the DTC codes. That would require your guy or an autozone hookup to a scan tool. I hope my clarification helps; and the graciouness of a FIxYa rating for this question would be greatly appreciated
