What does 'req' mean in the TPC display?

 

First you have to tell us what "TPC" means.

 

ditto

 

It's an acronym Porsche uses for the tire pressure monitoring system

 

Suspect it indicates "required" as in you have to tell the TPMS during initial set up which diameter tires you are running, along with loading, and other variables. Then the TPMS needs to initialize,--which can only be done when the automobile is underway. (This is to preclude the car's TPMS sensors (antenna receivers) from falsely taking in data from a nearby parked car with a similar frequence sending unit.)

 

i believe "requiem," as in your tires are toast. actually, i think edgy01 is correct.

 

Thanks guy's. I checked to make sure all the tire /rim specs were input correctly Which they were, but it's giving me the 'req' msg and the left side F/R is showing - .
