"TPMS Inoperable" message
Took the wheels off the '11, and put them on the '12.
Keep getting TPMS Inoperable message.
For reference, the TPMS sensors are THE SAME from 2011 and 2012 model years. Sensors were new in April 2014, and just stopped when put on the 2012 vehicle today.
Anybody have a solution? There are many posts on MB World about this, but the solution seems not to be documented.
Thanks!
Hooked up a computer thru the OBD port.
- deflated each tire & recorded each TPMS electronic ID #
- inflated the tires, and downloaded their ID # to the vehicle computer
- reset the TPMS - relearn function.
- drove for 10 miles and the TPMS reset.
Took about 25 minutes, and the indy was kind enough to do it for no charge.

The above solution resolved the problem.

Thanks for the tip!
