Hi Dara,
I swapped my wheels recently, put old TPMS sensors back in new wheel and tried to set tire location. I can't seem to get the system to detect when the LF tire has been deflated. I can go all the way from 33 psi to 15 psi and the screen will still show "deflate left front tire".

I had a hard time doing it on the old wheels and don't remember what happened but after a few tries, system was able to read everything OK. I have been trying for several days now and no luck. Is there a recommended procedure for that? I have tried it with the key turned to accessory position, "key on" position and even with engine running and still doesn't work.

What I have noticed is that the moment I start the location learning procedure, I get a couple of weird noises from the speakers (I guess that's the prompt to start deflating tire or switch to the next tire) but the system doesn't switch to the learning screen. I have to go back to vehicle info page to see the "deflate left front tire" instruction. After a short while, the system appears to be frozen since the door alert doesn't work either until I exit the learning procedure. I have disconnected battery, reset the Maestro RR module and still no joy.

Thanks

Does the TPMS light on the dash illuminate when you deflate the FL tire? At the very minimum, I recommend doing the location setting procedure with the ignition on. Most cars will not have the TPMS system powered up in anything less than the ignition position.

Yes the dash lights up when there is a flat tire. The reason I had to set location again was because the tire place switched the wheels around when installing the new tires. I know this because when I got the flat tire, the location on the screen was not accurate with where the tire actually was.

Also during the tire learning procedure, the dash will not light up even with virtually no air in the tire unless I drive a bit.

That would be an issue. If the car isn't reporting the low pressure on the cluster either, the TPMS isn't awake. Make sure you drive it and wake up the sensors before you set the location, and ensure the key is in the ignition position when you are doing the learning procedure.

I got it working. I tried the location setting right after I got home with key on position. System read LF tire location and the next thing I saw was "Learning Completed". I didn't get to deflate the second tire so I knew something was wrong. I flashed v1.3 (ever so reliable) and after 2 tries, it worked.
I reflashed v1.6 after.
So unless flashing firmwares require a relearn, it's all good.
Thanks
