Chip L Posted October 24, 2011 Share Posted October 24, 2011 2001 RX300 AWD 152K Single beep / chime while driving as transmission shifts from 1st to 2nd gear. The beep is repeatable (every time from 1st to 2nd). No 'trouble' lights appear. Thoughts appreciated. Chip Quote Link to comment Share on other sites More sharing options...
jaswood Posted October 24, 2011 Share Posted October 24, 2011 2001 RX300 AWD 152K Single beep / chime while driving as transmission shifts from 1st to 2nd gear. The beep is repeatable (every time from 1st to 2nd). No 'trouble' lights appear. Thoughts appreciated. Chip VSC/TRAC Beep is accompanied by dash indication but the dash indicator is so brief that when you hear the beep by the time you look down at the dash the indicator is already off. Idiot design. So if you're driving somewhat aggressively it may be the VSC/Trac beep you're hearing. It doesn't take very much yaw(VSC) or wheel "slip"(Trac) to trigger the VSC/trac functionality and it took me (also an '01 wannabe "AWD", 90K) a long while to sort out the unknown "beep" since my butt sensor isn't well enough tuned to detect the brief yawing or wheelslip/spin. There is some history of the yaw sensor coming loose from the floor mount and/or even more likely the steering wheel rotational position sensor being out of calibration. Any steering work, alignment, done recently...? Quote Link to comment Share on other sites More sharing options...
