I have a 2015 RC-F but no idea if TPMS is similar on all models so I posted here to maybe have more chance of responses.
I had a slow puncture in a rear wheel, the air was leaking from where the valve meets the rim, I took it to a tyre place & they couldnt get the TPMS off because it was seized & was going to break, so they asked me what I wanted to do, I said it was ok to replace it, so they broke it off & put a new TPMS sensor on that wheel, cloned the ID etc.
I drove away after but I noticed none of the tyre pressures were showing on the dash, the TPMS light wasnt on, I thought it might take a few miles to recalibrate or something, but it never came back.
I read the manual, did the turn on the ig, press the TPMS button under the dash, it flashed 3 times & then waited a few minutes, turned it off & back on again, didnt work.
Plugged in the diag tool, it shows all 4 sensor ID's & all sensors are reading a pressure.
Took it back to the tyre place, they spend 2 hours messing with it, resetting it all etc & gave up, refunded me for the job.
Anyone else had these issues, does it HAVE TO BE an OEM Lexus TPMS sensor? any ideas before I get ripped off by Lexus dealerships? would TPMS be covered by that "Relax" warranty?
So to sum it up, no TPMS light is on, all values on the dash are -:--, all tyre pressures are good, I did the reset procedure from the manual & all 4 TPMS sensors are transmitting & reading values when viewing them on the diag tool.
Anyone has any ideas I would appreciate it. Thanks.
