Nice... do an update please after the install. Would be interested in how easily you got them to reset and start working.

Quick update:

Wednesday Costco installed the Ore-Tek sensors for $56.00 (I had purchased and installed new tires last month, so they were more inclined to do it). They were very reluctant to use the Oro-Teks (they never heard of that company), and ran into some trouble with the required torque, since it was not listed in the instructions. Amazingly they called Oro-Tek and were able to get the torque numbers...I did not expect that from them.

Thursday my friendly dealer service rep plugged in Star and reactivated my TPM...for free...and left it like that, without fully resetting the system, which was what a wanted anyway. So I drove around for a while, hoping to see the system work, but it was not to be. I was able to reset, get to the "yes and No" prompt, but after driving around for a few minutes I would get the error message "drive to the shop!".

I went to the Oro-Tek website and I saw that the "learning" has to be done within one hour of inflating the tires, and if not done then, the tires must be fully deflated, then inflated again and then do the reset procedure. So that is were I am now. Tomorrow I will release a bunch of nitrogen into my garage...and try it again.

I will post the results...

Interesting observation about the Oro-Tek suggestion to deflate then re-inflate. I have seen some sensor brands state that to activate them the tire had to first be inflated to or above some high value (37 psi sticks in my mind).

One thing that seems to help the system reset and register properly sooner is being sure the tires are filled to the proper level before starting the calibration. Significant deviation (and especially a left-right imbalance) seems to slow down the recalibration. I can't give you a technical reason for this - it has just been my experience.

Also - when I had my sensors replaced the last time, my dealer overinflated the tires - rears were at 37 psi cold. I got a warning, and TPMS quit. After adjusting pressure and resetting, I had to drive for about 25 min before everything came back in - a longer than normal drive for calibration (which has varied from 5 minutes to 15 minutes, typically).

Skylaw ... that was 3.2 bar, or about 47 psi according to WIS. That may have been Beru specific though.

Mine has come back in after about 5 minutes of driving when I do that; up to 15 minutes if the pressures differ by several pounds.

Also: Be sure you don't leave the old sensors anywhere in the car. If one or more has any battery power, it can interfere with the new ones.

+1 on the old sensors being too close. and a +11 on the starting pressure. Use the figures on the gas flap door, for my S500 that was 29 front 32 rear.

I too had to go thru several resets to get all 4 working again. I THINK what happened with mine is I had tried so many times to reset that I put Control Module into a hard OFF condition. After leaving tire shop I drove about 20 miles and got the VIST WORKSHOP message after an owners manual reset at the shop. Got home and did the DAS thing and cleared the error codes, then did a hardware reset with the fuse pull. Drove around for about 10 miles and display came on with 3 of the 4 wheels showing inflation numbers.

Did another owners manual reset, got another VISIT WORKSHOP message. Hooked up DAS and noticed that I had good serial numbers on all 4, pressure, battery life and temps on only 3. Figured by this point that antenna in left rear was not doing its job and rather than try and swap rear wheels side to side to troubleshoot, I tried one more owners manual reset. and VOILA ! lazy left rear finally woke up and reported for duty.

As near as I can figure the control module polls each wheel independently with the left rear being the last. But mine was taking so long that it exceeded the allowed listening window before throwing a code and shut down . Until I had the other three up and running, then there was enough time to get Lazy Left Rear into the party on the third reset. That antenna may still be Not Quite Right but I am going to let it ride for now.

Well, I deflated the tires completely, waited at least the 5 minutes required, re-inflated exactly to car specs (29/32), reset the TPMS (yes/no prompt) and drove for 12 minutes, until I got the message "TPSM not operational, drive to workshop!". Then I tried it again...same after 12 minutes. I proceeded to pull fuse # 70...confirmed it is the right one by starting the car and getting a TPMS malfunction which I could not reset, re-installed the fuse, reset the system (Yes/No prompt to yes), drove around again for 12 minutes unit the message came back on.

Also, for the last 2 runs I removed the spare tire just in case it has an old sensor in it, even though it does not look like it has one.

In case I did not mention it, the sensors I installed are the ORO-TEK OBE-001...which on their website they list at the correct part for the 2004 S-430...but who knows...

Waaaaaaaaaaaaaaaa!

fxdeebee

Hate to say it, but you got the wrong sensors.. you have 433 MHz, you need 315 MHz, regardless of what Oro-Tek's site says..

I kind of suspected that, since a lot of the google searches for OBE-001 returned the dreaded 433Mz number...so Horror-Tek cost me $56.00 plus probably the $121 for the sensors, since I doubt I could return them after installing them. I was so naive and trusting of their website...and this is not my first online rodeo!

Notice no difference between North America and Europe spec models?

busflier

Yep!

I ordered the Titans 315 Mhz from OE wheels ($141 shipped) and they should arrive in a few days. I'm fortunate that Amazon will take the Horror-Teks back, even without their original cartons, so for now I'm only out $56.00 from the Costco installation. Of course now I would be too embarrassed to go back to Costco to install the Titan set, so I'll probably go to Americas Tire, which quoted me $23.00 per wheel to install. I'll pay the "stupid tax".

I can't believe (I can) I was that stupid...I read the whole thread, actually all the TPMS threads in existence, and I still ended up buying and installing the wrong sensors. To the voice in my head: you are right!

Thanks FXDEEBEE for you help in pointing me in the right direction...I would still be driving around praying at the dashboard message:Just Drive a few more minutes

The saga continues...

fxdeebee

Life Lesson #1202 completed. As long as you don't repeat the error, its all good and learning experience. In the end you will have paid just over half of -ONE- dealer unit installed. That's WAY ahead of the game. So :thumbsup: and carry on !


Oh, just to make you feel better, I finally got my GPS working with the proper antenna on the third antenna

Good work! I just recently updated my Nav DVD from Version 9 to 13...thanks again to this forum...it may have been you that posted that V13 was compatible with W220 (not listed on the DVD itself)...

Actually, it was ZeroGee that started it. Long story short...


ZG: I have 2013 installed, works
Me: Say what? 2013?
ZG: yes
me: Damn, must look into this. Skylaw !! Jump in here!

Update:

Titans arrived yesterday and were installed at America's Tire for $100.00 ($40.00 of that was balancing). Driving home I was not able to get the TPMS to work...got the dreaded "drive to shop!". I noticed the tires were extremely overinflated, so I waited until this morning.

I followed the instructions by deflating the tires to more than 70% (deflated fully)...waited 5 minutes and inflated to exact numbers (29/32). Disconnected the bluetooth puck, turned off my cellphone, pulled fuse # 70 and reinserted (for good measure) and drove around with the windows open until the dreaded ! showed up again. Tried two more times and the same. Then I remember I had the "Fast Track" transponder thingy in the car and tried one more time without it...no luck.

Close to giving up!

fxdeebee

"Tried two more times and the same."

Pulling fuse 70 both times? By pulling the fuse you are doing a total reset. That means you are losing the all the info it has managed to gain before timing out. Sensor serial numbers ( used to assign values to discrete wheels ), temperature and battery life. The system need a fair chunk of time to poll each wheel individually until all the data gets read.


I know, giant PITA, but try one more session with JUST resetting on the dash "R" button ( hold 3 sec minimum ) every time it does the "visit workshop" thing. Repeat as many as 4-5 times before giving up. I feel fairly sure that eventually all the info will get read into and retained by the control unit and it will flip over into normal operation. With one caveat, that the control unit hasn't gone sour.


If you can con someone into hooking up STAR you can check the TPMS system and verify that data is ( or is not ) trickling in.

busflier

Shoot I didn't realized that pulling the breaker will do that...or that it might need several "sessions" to read all the info. I thought that once you get the dreaded message it starts all over again!

Now that I know this, I will make use of my obsessive perseverance and will attempt the relearning compulsively until it works...or else!

Also, do you think it is necessary to "activate" the sensors by deflating the tires again for the relearning, or once they are active they remain so? The instructions from OE Wheels say to deflate to less than 70% to "activate" the sensors, and in a horror-tek video they claim that the relearn has to be done within one hour of "activating" for their IORO sensors. So I don't know if this is a general requirement or only the ORO-TEK IORO's.

Thanks for all the info...you rock!

fxdeebee

What it sounds like is that the Oro Tek "deflate the tires" instruction is forcing the sensors into "burst mode" i.e. not waiting to be polled but going into high speed catastrophic tire failure mode.


Having said that, i did find in WIS some info ( cant put my hands on the reference right now ) stating that sensors need to be inflated to 3.2 bar ( 47 psi ) to "activate" the sensor. Then deflate to normal pressure and then do the relearn by driving thing.


Let me try and dig out that reference and PDF it for you.




UPDATE:


found em...see attached

busflier

I'll try that...I assume it is safe to inflate the tires to 47 psi?

This is what I got with my Titan sensors:

fxdeebee

Yes.. check the sidewall of the tire.. should be something about "max inflation pressure" of about 50-55 PSI in really small print.

lganski

I went through the same thing with the Titan Sensors. I spoke with the Tech at Titan and they told me to deflate the tires to restart the learning process. It took quite a bit of time (weeks) for me to get them to register (with a soft reset from the dash) My wife thought I had lost it because I was letting the air out of my tires every night then going for a ride. I drive 50 miles one way to work so after numerous resets they finally took (you don't have to deflate the tires every time to do a reset, I just did it a few times till pressures started showing up). However all of my tires read 5 lbs high but other than that it seems to be working fine. Some day I will look into the problem. Its just really nice not hitting reset every time I get into the car.

busflier

Slight progress...maybe.

Today I deflated the tires, inflated to 48 psi (just in case) and then set the recommended 29/32.

Started driving right away and the first 2 times I got the malfunction message after about 12 minutes, as usual. The third time the message did not come on for 32 minutes, but after that I had to go home, so I don't know how long it would have been or if that was the time it was going to work . I drive 120 miles one way to work (but just once a week)...so I'll have time to test it again on the highway (I've been off this week).

I also noticed that today, after I get the malfunction message, I don't have to reset and select "yes" again. Just turn off engine, start engine, and the message "...drive a few minutes" is back on and the malfunction is erased. Before today that did not happen (I had to actively reset the malfunction and select yes again).

Thanks FXDEEBEE and Iganski for your invaluable help in troubleshooting this!

Success

Went for a drive...actually to Costco...10 minutes into it:

Tada!

Thanks!

WHAT?!?!?! and be actually RESPONSIBLE for what I say??? I don't think so !!

Update:

After I got the TPMS working with the recommended pressures 29/32, I re-inflated the tires to the proper (I think) pressures of 32/35. I have 18" wheels and Driveguards 245/45/18 96W. Don't ask me how I came up with those pressure numbers but is the best I could get. If anybody knows better please let me know...I found out there is a whole world about tire pressures ...and no thread about it...we should start one.

After inflating I took a chance an hit reset...so the TPMS would start "monitoring" these new numbers. Well...it took a couple of days of driving again (start and stop, running errands around town) but it finally came back up. During the driving it did not malfunction at all, it just kept the message to drive a few miles until the numbers showed up. I only hit reset that one time.

Hopefully this is the last update until the Titans start failing in the future. Thanks for all the help I got in this forum, without which it would have cost me $1,000 + at the stealer to get the TPMS working again.
