Hello i need an help.
I have lexia and 9.186 program version.
Several months ago, I disabled the Tire Pressure Monitoring System (TPMS) ECU module because one of my sensors was faulty.
I have now fixed/replaced the sensors and am attempting to re-enable the module and perform the sensor acquisition/learning procedure, but I am encountering an issue.
I am unable to successfully enable the sensors. I'm attaching a few screenshots of the process (which I can't include here, but they show the steps).
The strange thing is that when I try to start the acquisition, the procedure first instructs me to switch the ignition OFF. Then, it asks me to start the engine. As soon as I start the engine, the connection seems to be immediately reset/lost.
Could you please help me? Am I performing the procedure incorrectly, or would it be better to try downloading an older version of the software?

Re: Lexia enable ECU TMPS
Have you actually re enabled it?
You may need an 'exciter' to wake the sensors up.

Re: Lexia enable ECU TMPS
Update:
Add id sensors and now it's work.
In fact at the begin i have a real low pressure, after i have no alarm.
But the procedure for learning sensors go in error for engine power on. Any advice?
Other question, is there a system for look pressure of tyres on car display?

Re: Lexia enable ECU TMPS
Is there a way to display real-time tire pressure on the dashboard, or does the control unit only send a notification when a tire is flat?

Re: Lexia enable ECU TMPS
About the option inside autodiag, filter for deflation detection, what's the difference between normal and selective filtering ?

Re: Lexia enable ECU TMPS
I believe it only provides warnings, not live display of pressure (frustrating considering the ECU does have that data - the X7 is the same).Spix wrote: 09 Jan 2026, 19:39 Is there a way to display real-time tire pressure on the dashboard, or does the control unit only send a notification when a tire is flat?
Sorry not able to help on the other queries.
