TPMS PSI/Temp Data - Working or Not
 

I've added a spreadsheet to this post with all the data to date. Just remove the .pdf extension and you'll be able to open in Excel. So far I can't pinpoint any specific pattern.


All right folks. Attempting to track down why TPMS reads PSI and temp for some vehicles and not for others. HU_CIC, 3001 Ex Box, "rdc_safety" set to aktiv. If you set HU_CIC, 3001 Ex Box, "rdc" to nicht_aktiv it will remove the TPMS menu from the iDrive but you will still see green tires on the screen. Last note: Before the software update (Global) I couldn't get the PSI or temp labels to show. After the update I now get the labels but no readings.

Continuing from original coding thread:

Here's the data we've been collecting. Just reply to this post with the following details:

I'd like to really like to hear from pre 09/10 owners with the earlier TPMS units. I know we have a few post 09/10 owners that the readings aren't registering, so I want to know if it's working in any pre 09/10 builds.

I'll add myself here... works with both sets of wheels.

I have it and it works. What I noticed is that at times when you first start out cold in the morning it takes a minute or two for the info to come up. If the car has been driven it comes up immediately.

Shawn coded mine last Sunday in Houston. I see the indicators on the display but don't get data (just an underline). I can also see the units in settings and make changes to them. That is, I can change from psi to bar and is shows up on the display, but still no data.

Never changed the tires.

Maybe this is a dumb theory, but would it be possible that this particular feature working and the Sports Display (HP/Torque meter) in some cases and others not, may have some kind of relation with the fact that they don't have the CIC/Navigation Professional and only have the BMW Business system installed?

By the way, thanks @Dreamcar, Sean, Shawn and all that contributed for all this.. My E-net cable arrives Saturday!! Finally

Has anyone looked for or found the code to turn the rotational monitoring code off? I wonder if that (RPS??? I think) might be on and interfearing.

I'll try to poke around tomorrow if I get some time in my car to look at the code.

@dmunz:
FYI. TPMS is Reifen Druck Control, aka RDC, and FTMS is Reifen Pannen Anzeige, aka RPA.

No great breakthroughs so far.

Last night I activated FTMS. The RPA choice is just above the RDC FDL line (not RDC_SAFETY). It was set to nicht_aktiv, I changed it to aktiv. I now have an RPA ecu choice on my CAFD which has so many settings it's ridiculous. I was going through it, but just didn't have the time to delve deep into the tree.

I also adjusted two FDLs sitting in KOMBI that related to RDC, but my suspicion is that they are the FDLs that allow TPMS error codes to display on the guage cluster. Aktiv to Nicht_Aktiv.

This morning I started the car and reset the TPMS then drove away. Previously my TPMS display showed the pressure and temp icons (and green tires) but didn't give me anything else. I didn't get the dashes like many of you get. So after driving for about 200 ft I got the same display but with dashes now.

I'm going to change the RPA/KOMBI settings back to their original values one-by-one this afternoon to see what happens. Then I report back my findings.

Sean

I am happy to see you back on coding!

Thanks for pushing on this Sean. I hope we can crack it.

Update on my situation is I had the dealer check the TPMS and valve stems in case the tire shop messed with them. They said I have the original OEM TPMS and metal valve stems.

Did everybody check this value in ICM ? 2VB is the SA code for Tire Pressure Monitor.

2VB is standard equipment in the U.S.

I know this is a long shot, but I am going to ask anyway. For those without working TPMS, is your car also equipped with Active Steering?

Yes

No active steering on mine.

If Alex also has active steering then you may be on to something as stealth also has active steering.

Edit: Just checked he doesnt have active steering... But i am curious why did you think active steering is the cause?

No active steering on my F07 either.

@shawnsheridan,

I have active steering and my TPMS is working fine.

How is the data sent?
 

Are the sensors using Bluetooth? It might be possible to sniff out the signal and see what is being fed back to the system in the car.
