But then when you drive away next time the "check tire-light" will come on again, wont it!?Or... you can do what I do on the wifes Prius and my past Highlander Hybrid and plan to do on the CT. Summer tires have the TPMS monitors, winter tires and wheels use regular valve stems and are kept in the garage. In the winter, usually after about 10 miniutes driving, the check tire pressure light comes on. It will stay on till we get home and we let the car run for about 3-4 minutes and it receives the RF signal with the tire pressure. (By the way this works even with the car in front of the garage and not in it)
Not perfect, but beats about $300+ for additional TPMS stems and paying the dealer about $80 each time they reprogram the ECM.
That would be nice, but each is unique I was told, although I hear there are programable ones on or coming on the market. There should be, at least, a winter selector for when you run your winter tires to turn off the lamp or TPMS. On my Highlander they said there were enough spots in the ECM to take two sets and the spare, but you still had to have the dealer change them in the unit. I've seen a tool for about $150 (US) that you could change the ECM yourself, but not sure if it would work on the CT, I would think it would as it would have worked on the HH. You load your current summer tires into it, then the Winter tires and plug it into the OBD port and update between your summer and winter tires.......Cant I have air presure sensors with same codes in both winter and summer tires so that it works with both sets?
That sure would save everyone a lot of troubles. I had read and saw that they were working on developing a programable TPMS for dealers but the ones I had read about were in the $2k range far more then a individual would want to spend for their own use.I found this.. a system where they program the sensors instead of the ECU:
Seems like they have a gen2 too that can scan the standard sensor-code, but it was a bit more costy Programming Tools by Orange Electronic
Any one know if its possible to order those valves pre-programmed somewhere? Would be nice to just send the ID somewhere and getting sensors programmed back. Should be possible to have two sets of tires with the same ID then, right!?
Is it possible to disable TPMS or just drive with the light ON?I asked the same question last week. Apparently certain Lexus models have a selector switch in the glove box to allow the choice between two sets of rims. The CT doesn't - need to call the service department.
It will be a PIA if I have to have them code each time I swap rims (spring & late fall)
There is no way to disable, but you can drive with the light on. You can also do what I do on the Wifes Prius and my last few Toyota vehicles, keep your regular tires in the garage, after about 10 -15 min the light comes on when you get home let the car run for a few miniutes and the RF sensors will reset the light and TPMS system and your good for another 10 min or so. Most of my trips are under 10-15 min so my light usually stayed off.Is it possible to disable TPMS or just drive with the light ON?
I don't think I need all these toys, extra expense.
Well spotted. The button exists but is tough to see it's on the same panel as the footwell light just to the right of it . You need to get your head way under the steering wheel and use a flashlight to be able to see it.
