Calling TPMS experts...

2007 LR3 SE 4.4V8

Getting intermittent TPMS alerts "check all tyre pressures" - manually checking the tyre pressures (with three gauges) shows the pressure is fine.

Checked for faults with GAP tool and nothing logged for TPMS. Took Live Data feed from sensors and get this (which is obviously way off). I don't know how reliable the live data is - can someone else check their values ?




So I've heard the TPMS ECU can flake out but being mounted in the roof is a PITA to replace. Given the symptoms (or lack of them) does it seem more likely that the batteries in the sensors are all tired (no pun intended) and it would be worthwhile to spend money on replacing them first ? Does a low battery get flagged in the fault codes or the dash ? I'm guessing that because the alert is for all tyres that it's unlikely to be one of the wheel receivers ?

Any further testing that might help narrow it down ? For now I guess I could disable the TPMS or just ignore the light Wink

Thanks!

Bow down you are of course more highly skilled than I. If my steering wheel is on the wrong side of the car does that make it harder ? Rolling with laughter

Reading between the lines, do you suspect the ECU then ?

I refined my forum search string and found I asked something similar a few years ago but never really got to the bottom of it. Does anybody have a PDF of the "getting to the TPMS module" for the US version ?

I may just disable it in the CCF with IID and stop cooking with aluminium saucepans.... Rolling with laughter

If I disable it in the CCF but the module is still there, am I going to cause the CANBUS brain to explode ?
