Where is the vsc electronic module located on a 2000 lexus

check engine light is obviously telling you that you need to take to a lexus approved mechanic who will have the diagnostic equipment for your age of vehicle which is known as OBDI , there are many reasons for these symptoms mostly electronic so would need to actually be with vehicle to help better

the VSC is reading only when is dissabled

On this make the warning lights all come on together, the check engine light is the cause of all.
Hello
When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

When this light is on it is to signal you that a fault has occurred in the Vehicle Stability Control system and the computer control module has switched it off. In order to get the light off the system must be scanned with a special electronic system scanner to read the fault code data. After the fault code is read you begin the process of diagnosis and repair of the part or circuit that is the reason for the light being tuned on.

VSC - Vehicle stability control.

Can not be reset, will have to take it in for service, vsc pick up a code on your system, have it checked out soon.

Saw this on a Lexus user club site ---

• Vehicle Skid Control (VSC) senses the onset of loss of lateral traction and helps the driver stay on track. Input from four wheel-speed sensors, a yaw-rate (directional) sensor, a deceleration sensor, and a steering-wheel-angle sensor is communicated to the VSC computer. The system has the ability to reduce power and to control the brake actuator. Working with both ABS and TRAC, the VSC system helps the driver to compensate for loss of lateral traction, which can cause skids and loss of vehicle control. Lexus Vehicle Skid Control (VSC) is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether VSC will be effective in preventing a loss of control.

However, it appears Lexus owners who have reported this sort of problem did not have to do anything to fix except - things like .. uncap gas cap and put it back, remove battery leads for about 10 minutes and put back, tighten air filter hose ...all wierd.

Have you checked your owner's manual ?

VSC is Vehicle Stability Control. This is and electronic sensing which monitors and combines performance of braking, wheel slippage and handling, ect.
If this light comes on along with check engine light, it can be caused by a loose gas cap or faulty o2 sensor.

you most likely have an "air gap" or "tone ring" problem with one of your sensors or tone rings. i would suggest letting a technician diagnos which problem it is, as it is a diagnosis that requires some experience.

there is a switch under the dash to turn the vsc on and off. its on the driver side

My 2000 Lexus GS 400 just had the VSC/VSC off light and the check engine light come on. I would have to push the accelarator peddle all the way down to get it to go. Took it to the Toyota dealer and the code pulled up as the Throttle Position Sensor was out. Purchased one and having it put in. Will update if this fixes the problem.
