TPMS Computer Problem???
I have been driving my 2006 S430 4Matic for some time with dead TPMS Batteries. I finally found a deal on new sensors (Titan) and had them installed last night. The shop I took it to is a tire specialist. I get all my tires there. In any case they tried to reset the Tire Pressure Monitor and could not. They plugged their computer into the system and it would not communicate with it.
When I go to the TPM on the instrument cluster the message reads "Tire Pressure Monitor non operational" Do I have bigger problems than just the TPMS in the tires? I will be making an appointment to take it into my MB Indy but wanted to get some input before I do. Thanks for your help.

Pull fuse 70 ( red 10 amp ) under back seat. Fifth slot from the door side of fuse panel, top row.
This is hard reset of TPMS control module. Then do the instrument cluster reset, drive a dozen miles or so till the tire info shows or the inop message re-appears. You MAY need to do the instrument cluster reset a few times in order for the control module to poll all four wheels sequentially within the window the control unit allows before throwing a code and shutting down. Eventually it should work as info gained from each wheel is retained ( serial number of sensor, battery voltage, temp and pressure ) before the unit polls the next wheel.
Just did this on my '06 last week.
PS...make sure you are starting with the recommended pressures, check fuel fill door for pressures, mine are 29 front 32 rear.

Hi all, FXDEEBEE the fuse trick did reset the computer but the sensors will not register with the unit. I have reset it 3 or 4 times and no result. I drive 50 miles to work so it has plenty of time to register. This morning I sent an email to TITAN to see if they could add anything. If anyone has any ideas let me know and I will try it. Thanks

Yes, before I had them installed I called TITAN and verified the frequency since it was not printed on the device. I also double checked their web site because as you state some are 315 and some are 430 for my car. I did check the old sensors and they were 315 MHZ.

Over the weekend I am stopping at the tire place where I had them put in and have them give me a reading on these. If they can read the system I will have them enter the serial numbers in.

I'm having the same issue with Titan BE-004 sensors I installed on my 2006 S430. I removed fuse #70 for a few hours then did a reset on the dash. I drove several miles and the dash display went to the "take to workshop" message. I stopped and did another reset and this time all tires displayed with the proper pressures. I thought it was a done deal when the right status came up. However as I continued to drive home, the system went back to "tire pressure monitoring is non-operational". I did yet another reset and the 4 tires showed again, however this time one of them had a dash rather than a reading. I did another reset after that and now I can't seem to get it back to the readings. Are these Titan sensors just that flaky in communicating with the car's main unit?

When I had mine put in I went thru the same scenario. Pull the fuse again ( doesn't have to be for hours, just a couple seconds will do ) and go thru the whole procedure again.
My experiences are chronicled here .. starting at post 59

My Titans have been in for 5 months and have performed well to this point. I do occasionally ( like once a month or so ) get a dashboard message about being non operational but a dash reset clears it immediately.

Hi all, It took a few months of messing with it but my system finally came around. My car was in the body shop for a while with the battery unhooked, when I got it back the TPMS registered. It works now but the right rear comes up as dashes after driving a while and then comes back later. I spoke with TITAN about the problem and swapped my rear to front and the problem followed the tire. Titan send me a new sensor, yet to be installed.

Thanks for the quick response to my post from yesterday. I'll continue to reset the system with hopes that it will stick at some point. One thing i forgot to mention in my original posting was that another wheel shop had ordered the OEM Huff brand sensors and the system registered a few minutes later with no issues at all. The problem I did have was that the stems were leaking air very slowly and the shop was not able to correct it. They gave me a great price on the OEMs and I really wished they would have worked. With the Titans, air is tight and they fit nicely, however they are not registering as feasibly as the OEMs did. At this point, basing it on my struggles and from reading other posts, it appears that the Titan sensors are not as solid as the OEM's. To be fair, I don't know how they compare to other aftermarket sensors. I may have to consider just eating the cost of the Titans and look at purchasing OEMs again. Hopefully the next set will work.
To confirm, is the circled fuse on the image below fuse #70?
Thanks again

Yup, that's good old number 70. Just a thought. The TPMS system absolutely must have a good reference pressure to work from. Make very sure that your are starting the hard reset ( fuse pull ) on cold tires and your inflation is spot on with the data card on your fuel filler flap. Don't check it with a $2 gauge you get at the check out counter in Safeway. Spend $10-15 on a decent one. Consumer reports thinks highly of this model ..
Good Luck

I called OEWheels for help in getting the Titan sensors to register and the technician sent me a brief list of things to try with some suggestions that I had not seen before. I plan to try them later today and I will report back with the results. I will post the recommendations included in the checklist.

These are the tips I received from Titan. I can tell you that I have tried everything here over several days and have had no luck. I'm not sure what combination or sequence worked intermittently only once and was unrelated to these instructions, but it was when the system went into "take to workshop" mode. I stopped the car, turned it off, and then restarted and it immediately picked up all four tires. However it went back to "take to workshop" after driving 5 minutes or so. I know my main receiver unit works since there were no issues when I temporarily had the OEM Beru sensors installed as well. Hope this is helpful to others.
Common issues preventing successful relearning:
Sensors may need to be woken up before the relearn procedure can be performed.Toawakensensorsfollowthese steps:
Common issues preventing successful relearning:
- Old sensors are still inside of vehicle or around vehicle (old sensors must be 100ft away)
- Dark window tint interference (roll windows down during relearn )
- Bluetooth accessory interference (unplug Bluetooth accessories until relearn finished)
- Sensors are in sleep mode (need to be woken up by following procedure below)
Sensors may need to be woken up before the relearn procedure can be performed.Toawakensensorsfollowthese steps:
- Deflate tire(s) to 70% of their required air pressure
- Let deflated tire(S) sit 5 or more minutes
- Inflate tire(s) to OEM placard pressure
- Start relearn procedure

Does anyone know if the original spare tire on the 2006 S430 comes with a TPMS sensor installed? This is the only thing left for me to try but I don't want to take the tire out if spares did not come with TPMS.

I have the same car as you and mine did not come with a TPMS. You can find out by looking at the valve stem. They are quite different than the rubber ones normally used. My spare also uses a black steel rim.

You MAY have to go get the codes erased with STAR. Although the #70 fuse pull should relegate any code to STORED and not ACTIVE. Is it perchance the left rear that's slow to come on line ? That was my lazy wheel, and I just kept R button resetting till they all 4 popped in.
Dropping the pressure to 15-20 PSI might work also. What that does is prompt the sensor to go into burst mode ( that is.. faster data transmission ) as it thinks you have had a catastrophic blowout and should pop the warning in the instrument cluster straight away.

Thanks, fxdeebee for the additional tips. Do I need to go into a shop to get STAR cleared up or can I order of those OBD scanners to clear it up?
Right now I'm not getting readings from any of the tires. I've reset the system many times with no results. The only time I did get readings on all 4 tires with the current Titan sensors was the day after I had them installed. But 5 minutes later, the right back tire showed a dash only and soon after the system went back to fail mode. Not sure what happened and how it was able to read all 4 tires that one time.
When dropping the psi to 17, should I have to drive the car to trigger the system or are you suggesting to reflate them to the required pressure after so much time and then driving it?
Thanks again to all for the tips.

SWAG ( Scientific Wild Arsed Guess ). It MAY have been using cached data from old sensors, then started getting different serial numbers and went into re-learn mode. In the process, it MAY have timed out of the allowed receive window before getting all wheels learned and went into fail mode.. again.

Hold off on that for now. Lets try and start from scratch and do all the stuff from WIS, owners manuals and vendor sites for reactivating.
Repull fuse #70 for a few seconds ( ign off ).
Be somewhere you can inflate the tires. Fill all 4 to 48 PSI ( 3.2 bar ) I know, sounds high, but according to WIS " New tire pressure sensors cannot be read out because they do not send signals until a tire pressure above 3.2 bar has been applied " If your installer some how missed that....
Then adjust tire pressure back down to 29-30 PSI front ( 2 bar) 32-33 PSI ( 2.17 bar) rear. Do the dashboard reset and HOLD the R button at least 3 seconds. That should bring up the CHECK CURRENT TIRE PRESSURE YES /NO message. Select YES. wait a couple seconds. The message should disappear and TIRE PRESS. MONITOR REACTIVATED should come up. Starting the car will put TIRE PRESSURE DISPLAY APPEARS AFTER DRIVING A FEW MIN up.
Go for a drive. If it pops up with "visit workshop" do the dashboard reset again with a 3 second push of the R button . drive some more. If it does the "visit workshop" again, try the dashboard reset one last time.
If it fails to properly show tire pressures at this point, go to some place you can inflate the tires. Do dashboard reset and then deflate a tire to about 15 PSI ( 1 bar ) and see if it pops up as a red warning on the dash.
If it does, reinflate to proper pressure and move to one of the other three tires. Repeat for each tire until all 4 have been done and show up.
If they don't show up by now I am about out of ideas other than getting a STAR machine hooked up and checking that to see if the TPMS control unit is at least retaining the new serial numbers and battery life of the sensors. If it isn't, then the TPMS control unit may need replacing.

fxdeebee, I started going through the steps last night and had no luck with the top portion so far. I removed the fuse for about a minute, put it back in, then inflated all tires to 48 psi. Lowered the psi back down to 29.3 for the front and to 32.5 for the back. Did a dash reset, drove for a while and after 15 minutes or so, it came back with the "take to workshop" error. Got off the highway, turned off the car, and did another dash reset. Got back on the highway, drove for another 15 minutes and the dash came back with the same "take to workshop" error.
Drove home and lowered the psi to 17 on one tire... got the large red error on the dash to check the tire pressure. This was a good sign since it recognize that there was a drop in tire pressure. Today I plan to run through these steps on each tire like you suggest and see if all tires generate the same red warning.
I'm guessing that if all tires trigger the pressure error when dropping the psi indicates that the sensors are working and are sending information to the main unit?
I plan to reflate all tires back to specs once I test each tire, reset the dash, and go for another drive. Will see if that does it.
I'll let you know my final results once I'm done with the remaining steps.
Thanks!

I've been meaning to get back on here and report my latest results. I sequentially dropped the psi to 17 on each tire and the dash showed the big red tire pressure warning for each wheel. I'm not sure if I'm interpreting the behavior correctly, but if the dash showed the warming for each tire when the psi was dropped that low, wouldn't that mean that the TPMS receiver is getting a signal from the sensors? if it is, why wouldn't the system register the sensors at all?
I called Titan again today and asked for further guidance given that the previous instructions i received from them did not correct the problem. I was told that the sensors may need to be "waken up". Although i ran through wake up steps they sent me, the technician today suggested that I drop all the tires below 21 psi and to inflate them back to the appropriate level clockwise starting with the tire on the front driver side. He said to allow at least 20 minutes before moving on to the next tire and so on. I'm not totally convinced that the issues are with "sleeping" sensors, but I plan to give it a try.
Anyways, just wanted to share the latest with everyone. I will report back after i try these last steps Titan suggested.

Step you have taken already should have gotten the system up and running 3 times over. Take one more step backwards. Drag out the invoice from the vendor and ensure they are TT-BE004 ( 315 MHz ) and not the 435 MHz versions. ( see pic )
If yours are correct, then I am afraid that it may be time for STAR to look at your TPMS controller.
