I recieved the following Warning lights: VSC and Engine Check

VSC is vehicle stability control system. Read codes with a GOOD scan tool for more information. On Toyota and Lexus cars, using a scan tool other that the dealer tool will trigger VSC off and VSC lights, which can be reset using a procedure of key off, shift to certain gears, key on etc. as follows:

Friends,
For the benefit of any 2002 Lexus SC430 owners, I'll post the following item dealing with "Zero Point Calibration".
After hours of troubleshooting, I came to the hypothesis that the instructions MIGHT be different from 2002 - 2005 and 2006 - 2010 models. Below are the instructions I followed and WORKED on my 2002 SC430.
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:

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."

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:

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. • 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.
     

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

VSC is vehicle stability/skid control. Find the button that turns it off and on. Push the button to turn it on and the light should go off. Most cases systems like these will have a light stay on any time they are turned off. If the vehicle is a 96' or newer call around to your local auto parts stores and you should find one that will scan your vehicle for free and tell you why the check engine light is on. If the two problems are related the scan should tell you what part of the VSC is malfunctioning.

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.

Battery was diconnected for 1 minute and then reconnected. All lights are off.

the vsc light will come on with check eng light it disables traction control when its on when you fix or clear ck eng lite itll go off I have a 04 sienna it has bad cat conv and it comes on every couple of months I just clear it cause a cat costs like400 eventually ill fix it right.

As compgeek09 stated, yes the DTC (diagnostic trouble code) should be found out first. And yes, AutoZone or Advance Auto Parts should be able to retrieve the code for you. Then you should be able to tell how severe the problem is.

Yes, you should still be able to drive the vehicle. When the check engine light starts flashing is when you should stop driving the vehicle. Also, if your city/state require smog emissions, the vehicle will probably fail the test. Then you'll be required to repair the problem.

Lastly, Vehicle Stability Control. That light is probably related to the check engine light since it sounds like they both came on at the same time. The VSC controls engine power. Thus, if there is a problem with the engine (check engine light), the VSC can't do it's job.

Once the check engine light problem is repaired, the VSC light should go off as well.
