TPMS

[DD694]

Loren, do you know if the Porsche TPMS is available as a retrofit on a 997S? It was not available when I ordered my car last year. The sensor/transmitters can easily be installed in existing wheels.

I talked to a couple different folks about this and they both gave me the same answer. It looks like it would be a real pain because the factory TPMS uses the CAN network bus. So the wiring would not be in your car if you didn't order it.

There are at least a couple aftermarket systems that are very good - albeit you have to mount the display somewhere.

Loren, thanks for the effort. I was afraid it would be too difficult to be readily retrofitted. It does look like a very nice addition. I guess I will keep my tried and true hand-held digital pressure gauge.

Loren, does Porsche make a specific-to-order wire harness for each car it builds?

I wonder if the wiring for TPMS is actually present in the car, but lacks the RDK contol module and the four tire sensor antennae and wheel transmitters & sensors.

From looking at the 997/997S wiring diagrams there are only two wires that connect from the RDK control module to the Instrument Cluster that are CAN network connections - They are CAN Komfort High and CAN Komfort Low.

Yes, custom for every car.

The schematics always show a fully configured car - which very few are. Porsche simple does not put in wires for options that were not ordered (i.e. PSE, Xenon, etc.). Probably save them a few dollars in costs - but costs them in the retrofit market.

Loren, thanks for the response, even if it is bad news. Another reason to avoid first year of a new model, I guess.

I havn't seen anyone ask this question in 2006.

Not to beat a dead horse, but it seemed that tpms was not available in the 05 997 as a retro, what about the 06 997S, still looks like a no go. I missed it on the build sheet also.
