2003 Lexus ES: VSC, TRAC OFF, ABS lights ON?

In this type of cases check engine light is not illuminated and brake function normal.But you notice VSC/Trac off and ABS lights come on.

Also in some cases the driver has noticed Vibration too.
But i will say that,The vibration is not likely related to the VSC. That is probably tire or brake rotor related.
And as this Lights come on,i suggest you to first retrieve the Error codes.
The procedure is as follows:----
 Place a jumper wire or paper clip in TC and CG. IF there is a code 12 for example with the key in the on position the check engine light will flash one time then a slight pause then two flashes. If there is more then one code the others will follow.

It's a matter of inserting a jumper wire or one small paperclip between the two terminals. Once this is done turn the ignition key on and monitor the vehicle skid control light or VSC light and the ABS light. When the key is in the on position and this jumper wire is installed the light will flash a series of codes as I explained above.

In most cases you will receive code 43,31 and 35.

I will give details for all three.
The VSC light flashes as 4-3 interval (4-3 ...4-3 ... 4-3...etc.) and the ABS light flashes a 3-1-3-5 interval (3-1-3-5 ... 3-1-3-5 ... 3-1-3-5 ... etc).

The code 43 means low battery voltage to the actuator for the abs and VSC system. This can be a bad battery or poorly charging alternator to a problem with the connector to the unit.
The 31 and 35 indicate a problem with the Right Front wheel speed sensor(WSS). The 35 is an issue with debris on the tip of the sensor. Focus on the right front sensor repair first.

The right front WSS is on the passenger side.The right front is always as you're sitting in the car which would make it the passenger front wheel. The only way to accurately test and alternator is by reading the voltage at the battery should be between 13.2 and 14.2 volts. You would need an amp meter in order to test the current flow or output of the alternator. Typically though if you're getting at least 13.2 V the alternator normally is charging fine.

PLEASE NOTE:---If the system is no longer flashing a code there may be an issue in the computer for the VSC system. This may require a scan tool to get in to further diagnostics of the system.


ONE MORE HELPFUL INFO:---
You can continue to drive this vehicle. You just will not have ABS function or vehicle skid control functions. It will accelerate and brake as a normal vehicle.




This details will help.
Thanks.

2008 Toyota Highlander Hybrid: Warning Lights Abs, Vsc & Brake Are On?

VSC/Brake/ABS Lights Coming ON.
This types of problems are noticed on many Toyota Highlander models.
Basically in this types of cases you will notice that  motor/pump sound/noise coming from the right front of the engine everytime car is unlocked.Many car owners dont understand this problem.

First thing i will say on this case is get the error codes retrieved from cars computer.
There is manual procedure to retrieve the error codes by jumping the pin/wires.

In most cases the Error codes Received is
(ABS) - 42, 98.
(!) - 36, 66, 69.

If you receive Error code 69 then its problem here.

THE CODE 69 HAS TO BE THE FOCUS. This means there is a fluid loss or the Accumulator which is part of the ABS actuator and VSC unit is leaking internally. This is why you hear the motor buzzing. It is trying to pressure up the system and can not. More then likely the actuator assembly will have to be replaced if there are no visible external brake fluid leaks. The other codes all have to do with reinitializing the system and calibration issue caused by the failure of the accumulator pressure.

One more important  detail.The ABS actuator has nothing to do with the hybrid system. Provided the brake pedal pressure feels normal and the stopping ability feels normal you should be fine to drive. However if it's an accumulator leak internally in the actuator it could cause intermittent low or no brake pedal effort. At this point would be unsafe to drive. The ABS actuator normally houses the accumulator on US model made Vehicles.
On other Country made vehicles the Actuator is separate from the pump and booster motor assembly.

This details will help.
Thanks.
