Tyre pressure sensor warning light delete ?

[harley metisse]

Hi all, I am new to this forum, and the Rav4 section, but I am having problems with the tyre pressure warning light on my 2013/63 plate Rav4 2.2d.

Earlier this year I had new tyres fitted, all 4 of them and in the last two months the tyre pressure warning light has come on. I suspect it may be a low Battery, because I would guess they have not been changed since the truck was new and the garage said not to change them when the tyres were done. However, I don't want to have to take all 4 tyres off again now just to find which one it is. 

Is there a method of deleting this from the ECU/system ?

My pressures are all good, as per instructions and they get checked weekly as part of the wash and clean etc.

Help.

Cheers

TPMS would have been a mandatory fitment for this generation Rav4 as it's Type Approval would have been gained after November 2012. So unlikely to be a delete option.

Aside from that it, a working TPMS is also an MOT requirement for this age of vehicle.

They generally last 10 years but it is an expensive thing to take care of, albeit every 10 years  

If yours doesn't have a display like the newer cars do, the only way I know of to figure it out is with a special TPMS probe - Most garages should have one, but you can get chinesium ones from eBay for not too much. They ping the sensors and report back things like their code, which you'd then enter into the ECU if you were coding in new TPMS sensors.
