Hi guys, complements of the season. So my tyre pressure shows correctly on my instrument cluster, the issue is it shows a TPMS error after few minutes of driving which shows a - for all tyres. I believe the issue is the tpms module, Can anyone direct me to where the tpms module is on this vehicle so that i can replace it. If there's picture of this, i would appreciate.

This is from the 07-08 Helms, hopefully it's accurate for the 06 TL?

 

I replaced the rear speakers and GPS antenna unit on rear deck (removed backseats)

Everything on GPS works fine and sounds good now.

Now the TPMS is showing system error (not one tire or anything), have triple checked tire pressures and drove car for over 30 min on several trips around town.

Could I have damaged a TPMS cord removing and reinstalling the back seat?

 

It looks like one has to remove the rear seat-back to replace the TPMS control unit; therefore, if you were doing the indicated work above it's possible you 'tweeked' the control unit base to affect communication?
