Troubleshooter Posted December 10, 2003 Posted December 10, 2003 :) I have a 1992 LS400.150K miles. When Accelerating, The (TRAC) Light illuminates than goes off. Is their any way to retrieve the code for (TRAC) system? Troubleshooter!
wwest Posted December 10, 2003 Posted December 10, 2003 If a rear wheel slips, even sligthtly, during hard acceleration Trac will activate. If you're sure there is no slippage then you need to look into the cause.
Troubleshooter Posted December 10, 2003 Author Posted December 10, 2003 So its normal for the trac light to come on? and when you mean slip do you mean spin?
wwest Posted December 11, 2003 Posted December 11, 2003 Spin..... Well, not exactly. The Trac ecu watches the ABS sensors at the front and compares the front rotation rate with each of the rear wheels, individually. If either rear wheel should turn faster, for even a short duration, say a 4" wide plastic crosswalk strip that's wet, the Trac indicator will illuminate briefly. Therefore my use of the term "slip", no spin. Obviously it would also do it for a true "spin".
