Question about 2006 Toyota Sienna

1 Answer

VSC Warning Light

As I was driving on the highway this morning, the VSC Warning Light came on and the dash now says VSC Off and there is also a check engine light that came on at the same time. I have the same problem on a different model - VSC & check engine lights came on simultaneously on my 2005 Sienna (pull down only offer 04 or 06 models but mine is an 05). Any solutions or suggestions?

    My 2006 toyota sienna has same problem today, check engine and VSC light both on. And the engine is shaking, which is unusual and the first time we see it.

    This happened to me last week for my 2006 Sienna. Check engine, VSC and Trac lights came on together. I went on craigslist and bought a odb2 scanner (actron 9125). Its says that my O2 sensor is not working. I've ordered one online, and waiting for it.

The Trac light comes on automatically, in conjuction with the Check Engine Light. You need your vehicle scanned for DTC codes.

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."

2006 Highlander - Check engine light and VSC light on. What does this mean?


you will need to hook up a scan tool, I know many parts stores will loan you one or let you use it in the parking lot, VSC could have something to do with a wheel mounted speed sensor, did you hit something? any noises, try this and see if it goes away
    • 1 Shut off the vehicle's engine and apply the parking brake to protect yourself while working on the vehicle.
    • 2 Open the vehicle's hood and examine the engine compartment. Locate the air filter box mounted to the left of the engine. The air filter box features a black exterior, square in shape, and a large ribbed intake hose.
    • 3 Check all of the small black vacuum lines surrounding the air filter box. Reconnect any disconnected or loose vacuum lines you find.
    • 4 Start the engine and drive the vehicle to clear the "VSC" warning light displayed on the dashboard. If the VSC light fails to go out after driving the vehicle normally, proceed to the next step.
    • 5 Park the vehicle, turn off the engine and set the parking brake. Open the vehicle's hood and disconnect the battery's negative cable for 15 seconds, using an appropriate size socket. Disconnecting the negative battery cable will reset the vehicle's computer and clear the "VSC" warning.

WHY DOES VSC & CHECK ENGINE LIGHT STAYON


diagnostic reader and or workshop time required to
to fix both VSC and engine light faults /codes


VSC is brake /traction related ..... this is one explanation

It would appear that system braking, traction control, and possibly some anti rollover control is dis abled if this warning light is on. So it is both fuel in efficient and possibly dangerous to drive with this light on.

engine light

there are stored fault codes in the engine computer module pointing to faulty sensors on the car needing to be checked or replaced

TCR off, VSC and engine check light are appear sometime while I'm driving. I already checked gas cap, engine oil, break fluid ,air filter and wiper water and water cooler tank and also took off batter


Cluster warning lights

Whenever this warning or any other stays on in the dash it is indicating that the systems control module has detected a fault, it then disables the system as long as the light is on. You must now have the dealer hook up a special electronic diagnostic tool and "scan" the system for the fault code that is stored for the problem(s)

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.

Both the engine lights and the VSC warning light appeared on the dash simultaneoulsy this evening while driving - what might this be?


Had this happen to my '05 Vibe (Matrix evil clone) recently. Mechanic read & reset codes. The non-flashing Engine light showed 2 large emission leaks. The VSC could be any number of things. He said hopefully it was a false positive on the VSC... potentially expensive to fix. Lights stayed off for a couple weeks & are now back on. I'm planning on seeing him later today. Also, said stability light stayed off, it is still working. fwiw...

My vsc trac warning light and check engine light went on


Please, make your mechanic check the ABS computer. My RAV4 did the same thing, but the mechanical components were alright. After a while, I almost fell off a cliff because my brakes stopped responding properly. When further checked, my mechanic discovered that the ABS computer was damaged. The part alone costs a whooping $3 thousand bucks, not including labor. So, beware and take precautions. Your life may be endangered.

What is a vsc warning light on a toyota estima hybrid ?


It stands for Vehicle Stability Control When the VSC system takes control it activiates stability correction. The slip indication light flashes while the buzzer activates. The VSC is able to operate at all times except when the centre differential is locked. When the centre differential locks, the VSC-OFF light in the combination meter illuminates to inform the driver that the VSC function has been turned OFF. The centre differential lock is designed for freeing the vehicle if it is stuck in mud for example, however it would be difficult for the vehicle to free itself if the engine output were reduced due to the operation of VSC. Therefore when the centre differential is locked, the VSC function is turned OFF.If a malfunction occurs in the VSC system, the VSC warning light illuminates to alert the driver. If the vehicle with VSC begins to oversteer or understeer because of an emergency avoidance measure, or by excessive speed in a corner, VSC will automatically activate. By adjusting the engine’s power output and braking each wheel independently, VSC helps to return the vehicle to a ‘zone of stable operation’..
