Question about 1999 Lexus LS 400

3 Answers

ABS light, VSC light, and battery light all came on at the same time. VSC light is an easy reset, but it appears vehicle is running off battery charge only. I had battery checked, and it is 1-year old and operating fine. Serpantine belt? Wire connection to alternator? Any suggestions would be greatly appreciated. Thank you in advance

Your alternator has to produce at least 13.1 volts to recharge the battery. If less is produced then possible causes are alternator, wiring, fuse, drive belt. Your ABS and VSC modules will self protect and shut down when low voltage is detected. Repair the charging problem and the warning lights will be sorted too.

What do the letters vsc mean on the dash


Is you vsc light on by itself, or is it on with a Check Engine Light as well. If it is just the VSC light then you need a Zero-Point calibration. This is supposed to be only done at a toyota/lexus dealer. They take out the VSC computer and run their diagnostics program and reset and configure(calibrate) your vehicles VSC. I personally would disconnect both battery terminals for at least an hour, even better overnight, this should allow enough time to have all the electricity drain completely from those computers. Hopefully this would reset everything. I would try this before going to the dealer, try to save some money. If it is the VSC and CEL(Check Engine Light), then you would have to get the codes read at AutoZone....they do this for free unlike the dealer and then post your codes up on this forum. Hope this helps.

I have a 2001 Sequoia replaced connectors to battery. Now E brake light ABS light Trac Off and VSC Trac light are on. I disconnected ground and let it sit. Had code ran and it said open closed circuit abs?...


More than likley its your VSC computer (VSC Trac, VSC Off, E brake and ABS brake lights all lit). This problem has been sited on other Sequoias that had the TSB brake caliper/rotor upgrade (recall) and that more than likely the VSC software or computer was not updated to meet the demands of the newly installed brake upgrade.

Vsc light and traction control


When the VSC and trac light comes on, Your vehicle enter a fail safe function the ECU rejects any open request from the VSC system and your vehicle operate regardless of ABS,TRAC, and VSC. Having it cleared without corrections will allow the light to come on. If the VSC is seeing a large over steer the VSC and trac light comes on.(even if its under steer).If the ABS ,Trac is correct you will need to seek zero calibration.This is done through the DLC connection in the hood.The easy way to reinitial lize steering angle is done by keeping steering wheel in the straight ahead position (driver window down) disconnect the negative battery, and reconnect , turn key on . The other way is to go to the engine and find the DLC again driver window rolled down steering wheel in the straight ahead position. do not shake the vehicle you must be on a true level ground. No heavy load in the vehicle and no entering the vehicle untill this is complete Turn the key on at this point you will do everything through the window you cannot enter the vehicle.in the hood where the DLC is at you will short pin Ts and CG with a paper clip 4 times repeatedly within 8 seconds. There the VSC will go to zero point.Turn key off (again turn ignition off through the window) make sure you remove the shorting out of Ts and CG. Now your done. 10_13_2011_4_27_16_am.gifFor Rav4 use you DLC 3 its under the driver dash.As for the pin location its on the cover of the DLC 3

My lexus just quit working, it will crank but die when you put it in gear, the check engine light came on with a code of VSC any ideas. Thanks.


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 ?
