sportcrossing Posted October 5, 2004 Share Posted October 5, 2004 Any suggustions for disarming the VSC on my 2002 Sportcross? Although I think it is a great invention for the novice driver it almost drove the car off Sherman pass in WA at about 90mph. I understand newer models have a switch. Is there anything I can do to upgrade or bypass? Quote Link to comment Share on other sites More sharing options...
steviej Posted October 5, 2004 Share Posted October 5, 2004 why are you driving the Sherman Pass at 90mph in the first place. If you turn the TRAC control off, you will may achieve the feel you seek. Think twice about this. steviej Quote Link to comment Share on other sites More sharing options...

It is a little scary when you cant power through a drift... I finally found the TRAC button under the radio, had to pull out the owners manual to locate it. four months in the car never saw it there. Thanks! I am totally impressed with the IS300 Sportcross, it's like driving a cart with adjustable seats, and airconditioning... JonA...

bartkat Posted October 7, 2004 Share Posted October 7, 2004 Oh, I thought you were asking about VSC. Even a novice driver would have spotted that trac button right away. Quote Link to comment Share on other sites More sharing options...
sportcrossing Posted October 8, 2004 Author Share Posted October 8, 2004 TRAC / VSC... Okay still learning Lexus lingo... Maybe someday I will be as fast as you... My weekend job is driving sprint cars, so this is all new to me. Us old guys are used to making decisions for ourselves and not having to rely on a computer to do the driving... I must admit that this Sportcross is a better balanced ride than a lot of stock, and superstocks, that I have driven, it's a little under powered but gets the job done... Have fun, life is only one tach dive away! Quote Link to comment Share on other sites More sharing options...
steviej Posted October 8, 2004 Share Posted October 8, 2004 sport, keep in mind that TRAC and VSC are two different things. Only the TRAC has the specific cancelation button. I am not sure if VSC still works regardless of TRAC being on or off. steviej Quote Link to comment Share on other sites More sharing options...
bartkat Posted October 8, 2004 Share Posted October 8, 2004 Try keeping your illustrious weekend career on the track, and try to follow the rules while on the road and you won't have to be a Lexus terminolgy expert. Just gas up and drive, with no further attention needed. Quote Link to comment Share on other sites More sharing options...
sportcrossing Posted October 11, 2004 Author Share Posted October 11, 2004 :P Okay so I had it partially correct... Thanks for the input. Here is what I have determined Lexus TRAC senses the onset of wheelspin, then selectively applies the brakes and automatically transfers power to the driving wheel with better grip. TRAC works in conjunction with Vehicle Stability Control (VSC). VSC senses the onset of a loss of traction in a turn and orchestrates the brakes and throttle accordingly. Of course factors including speed, road conditions, driver steering input, and throttle position, all will affect whether VSC will be effective or detrimental in what the vehicle determines is "loss of control". From what I understand about the VSC it is primarily a steering control system, and TRAC is a combination ABS/torque application. Understanding this... switching off the TRAC will not stop the VSC from dampening the throttle and correcting steering angle... A little scary... Am I the only one that has experienced this?

steviej Posted October 12, 2004 Share Posted October 12, 2004 that is how I figure it too and have experienced both systems in action. steviej Quote Link to comment Share on other sites More sharing options...
bartkat Posted October 12, 2004 Share Posted October 12, 2004 If you want to learn about TRAC, just leave trac turned on and try a couple of burnouts. That will show you real fast. Remember though, trac and limited slip dif. are two totally different things. Quote Link to comment Share on other sites More sharing options...

As with any vehicle that is new to the driver you want to know what your limitations are. I am very satisfied with this car, it meets my needs for traveling long distances, and adds a spot of fun to the drive. I was able to get it on the track for the first time last night. It performed as expected, and ran very consistant laps. For a stock ride the Lexus boys really did a good job with this one. Quote Link to comment Share on other sites More sharing options...
