TPMS disable

[apcbbb]

I have a TPMS light flashing then continually on with my 2007 SC. Tyre pressures are good and steady. I’ve disconnected the 2 plugs under the radio. The light does NOT now come on with ignition but after starting the engine it flashes and then is solid. I don’t have any fancy OBD or tech gadgets. Is there any way of firstly disabling this and secondly sorting - cheaply! I appreciate thre have been a number of posts re this but I can’t find a clear answer. Any help would be much appreciated.

I have pulled the plug on all 3 of my SC without any light issues. This has been on a facelift and pre face lift. 

Have you pulled the correct plug?

Thats odd as I have also done mine as well without any issues as soon as I disconnected the two plugs. Is it definitely the TPMS light and not the VSC one?

Can this be done on a 2007 GS300?

If these are the original TPMS valves, then I would suspect that one or more of the batteries has failed.  Depending on mileage, they are. considered to have about a ten year life.

If you take the car to a good tyre retailer, they should be able to check the state of the valves.  When I had to have one replaced, it was £65 fitted - which was better than a Lexus dealer.

If the tyres need replacing then that would be a good time to do it, as the tyre has to be removed anyway.  And you can always negotiate a deal.

Of course you could just ignore it - some owners find a small piece of black tape over the flashing light solves the problem!

But the TPMS system is a safety aid and early warning system.  For your own safety - let alone that of others - it should be working.

Thank you all for your comments. I appreciate the safety aspect but happy to be without until I need new tyres!  It is the TPMS light and the plugs are the white and blue under the radio. Am I missing something? Should I disconnect the Battery for a ‘hard’ reset? - tyres still at good and steady pressure.

I have TBH and admit I am a bit of a numpty when working on cars, but even I managed to do this after watching a video on YouTube but a Lexus independent  said he has simply removed the bulb or LED? From behind the dash!! I cannot vouch  for this 😭 as I say i disconnected the plug with no problems STEW👍
