Question about 1999 Lexus LS 400

1 Answer

I have a 1999 Lexus LS-400. Appears to have charging problems (ABS, VSC, & Battery lights on). While running if I disconnect red terminal, car remains running (alternator). Starter checked was OK. Battery was leaking an oily/acid fluid from water fills, Pep Boys replaced battery under warranty and continues this on new battery. Battery charge is being drained if I don't disconnect terminals at night. Any troubleshoots appreciated. Thank you. Pat Nangle

Firstly check with your car scanner ,read for fault code, as my experience the alternater fault due to leak in alternator regulator ,check with multimeter for your voltage, at least with light and air con on, it should at least 13.6volt.normally with alternator light on when engine running.conform alternator,replace one thank you

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.

The vsc light is on


VSC (Vehicle Stability System) Sound like a problem with the ABS system, scanned with some reader code to know exactly which code stored there.

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...


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.

My vsc light and the vsc off light is lit up on my 99 lexus gs400, what does it mean?


It it's like the ASC button/light on a BMW it means you have a problem with either you ABS, Traction Control or possibly one of the sensors. Sorry to say it but you should get it into a garage soon. When mine went on my BMW it was a wheel speed sensor and the car basically shut off the ABS and Traction Control as it's not working correctly. If you're not used to driving without these features it can lead to an intresting drive to say the least. I'd get it into a garage asap!!!

VSC/ Check Engine Light


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.
