1998 Lexus gs 400 vsc light stay on -solve this-

If the warning lights for the VSC and ABS system are illuminated while the vehicle is running, your vehicle is indicating a fault in the anti-lock brake and vehicle stability control systems. These systems utilize the same components to operate, so when a fault exists, it often causes both lights to illuminate.

A diagnostic test is required to troubleshoot these systems; I would suspect the "beeping" to be related to the lights being on, and the fault being present.

It sounds like the alternator packed in. Get it checked out.

check your oxygen sensor,replace it..

take to local parts store to retrieve code vsc/trac are in failsafe because of thcheck engine light once you have code then we can diag problem with engine

VSC = Vehicle Stability Control, its possible that you have any wheel sensors problem.

I have a a 99 gs 300, check engine light is on as well as the vsc light. What is that and needs to be to done to fix it.

i have a 98 lexus gs400 my battery light came on......do i have to replace my alternator?

vsc shuts down any time check engine light comes on. repair engine light problem, reset computer monitoring system and vsc light will go off. must scan computer to pull codes for check engine light and go from there.

when the check engine light is on it is to alert you to the fact that a trouble code has been stored in the computers memory, there are over 200 such fault/trouble codes so guessing is not an option, u will need to have the OBD 2 engine control system tested and then post the trouble code back here, there will be a code.

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.
