john79904 Posted July 24, 2012 Share Posted July 24, 2012 Check Engine light and VSC/ Trac off issue from the owners manual I first found that the gas cap was the root problem. From this forum I found that the VSC and Trac lights could be reset with a jumper on the OBDport, or disconnect Battery BUT my motto is IF A COMPUTER can do the job why use a simple jumper . I already own an ODB port to USB converter - about $20 Download free diagnostic control software - may choices are available, I use easyOBDII.com which is free With this cool setup you have the laptop in the car, and not only can you reset all the problem codes, but get a whole ton of other information, including running engine real time parameters. Have fun Quote Link to comment Share on other sites More sharing options...
armandolo Posted July 25, 2012 Share Posted July 25, 2012 Does the Software you mentioned resets the VSC light? Or does it read the trouble code related to VSC? I Own a OBDII tool and did reset the CEL after I changed the O2 sensor. The problem is the VSC that I could not reset even after following Toyotas Procezude for Zero Point Calibration Quote Link to comment Share on other sites More sharing options...

mlbeck Posted July 6, 2015 Share Posted July 6, 2015 2004 GS430 with the VSC/VSC Off/Check engine lights on.........just started this morning. Tightened the gas cap, nothing yet. Maybe I should give it a few days? Took it to AutoZone, ran the codes and I was told that a few of the valves are mis-firing and that I'm in need of a "tune up". This sound right to anyone? Considering doing the reset with the paperclip.........anyone know what "pins" I would use for my make/model? thanks so much! Quote Link to comment Share on other sites More sharing options...
1990LS400 Posted July 6, 2015 Share Posted July 6, 2015 Those Auto zone guys have mis-firing brain cells - complete B.S. What are the error codes? Many issues can trigger the CEL and VSC OFF. Any other symptoms? Quote Link to comment Share on other sites More sharing options...
mlbeck Posted July 6, 2015 Share Posted July 6, 2015 No other symptoms really. I just took my car to a shop for a state inspection on Friday so I'm not sure if they did anything that would throw the code. They check things like brakes, tires, etc. Lexi seems to be running okay to me. I can try to disconnect the battery I guess or the good ole paper clip trick.

ajfuller51 Posted April 10, 2017 Share Posted April 10, 2017 Thank you, thank you, thank you! You guys are the best! I love reading the posts and suggested fixes. As a female, I feel empowered by coming to this forum. I appreciate the help because the dealers and unreputable mechanics can give bad information.
