ducada Posted April 13, 2011 Share Posted April 13, 2011 I have a 2006 ls430 and I keep getting a low ire warning. I went and had my tire pressure checked and they are fine. How do I reset this warning? Quote Link to comment Share on other sites More sharing options...
curiousB Posted April 13, 2011 Share Posted April 13, 2011 Follow the tire pressure "initialization" procedure in the manual. Quote Link to comment Share on other sites More sharing options...
aqbill Posted April 17, 2011 Share Posted April 17, 2011 And don't forget the spare tire! We had problem with wife's RX330 and it was the spare tire. Now I won't forget! Quote Link to comment Share on other sites More sharing options...
jac430 Posted April 17, 2011 Share Posted April 17, 2011 The spare tire is not measured in the LS430. Some cars have direct sensors that measure the air pressure in the tires, but that is not the case here. All measurements are indirect. The sensors for a.o. the ABS measure the rotation speed of all individual wheels, and if there is a change with what it used to be (just after "initialization"), it reports that there is a problem with the tire tension. Like curiousB said, just initialize (as per instructions in the manual) and take it from there. Hope this helps. Jac Quote Link to comment Share on other sites More sharing options...
