Tire Pressure Monitors?

I'm about to swap out the F1's for RSA's mounted on another set of original SRT8 wheels for the winter. These wheels and tires are brand new take offs with tire pressure monitors already installed. Anybody know what has to be done to sync the tire pressure monitors to the computer so that it will recognize each wheel by right front, etc. Or do they just link right up with no help? .

Well, I don't know for sure; but I would think that these wheels with factory sensors, it should link right up.
How about it, anybody got actual experience with it?

I just put my stocks back on for the winter and put away the 22's. The sensors were detected and there was no reset or sync needed

I have an '05 and it did not come with tire monitors... do you think that if I add them that the computer will recognize them?

Excellent, thank you guys. The manual did not say. As to the 05 here is a quote from my 06 manual...

"The system consists of tire pressure monitoring sensors attached to each wheel through the valve stem mounting hole, a central receiver module, wheel sensor trigger modules mounted in three of the four wheel wells, various tire pressure monitoring dispay messages in the EVIC, and an amber colored indicator lamp."

So my guess is no, it won't work, you will still be missing most of the stuff that makes the system work.

OK, i'll post this here (i'm also going to start a new thread).

My original set of wheels were stolen almost 2-months ago. The original TPM sensors obviously went with them. My insurance replaced the wheels and tires, no problem.

TPMS System has'nt worked right since. The car has been back to the dealership 4-different times, and the issue has been escalated to the top level of DCX Star. Still no success.

After talking to the service manager & other techs within the dealership, this is a well-known problem for all '06 300's equipped with the system.

As of today, Dec. 08, 2005 the system is still NOT working, and the dealership techs (some with over 10+ exp. and all the certs) have NO F**KING clue how to fix it.

Replace your '06 wheels at your own risk is my input. If you don't mind the intermittent "ding-ding" and warning lights, then go ahead.

Hmmm....its been 2-months now, and the service techs at the largest Chrysler dealership in Michigan STILL have not been able to diagnose the problem.

Replaced everything in the system at least ONCE. Car has been in for a "fix" four (4) times now. Each time, the tech's look even more puzzled as to why it does'nt work.

Long story short, I have a replacement set of '06 wheels. The TPMS system has not re-sych'd since.

This has been escalated to the top of DCX STAR. Still no f**king clue!

To anyone considering replacing their wheels (voluntary OR involuntary), think twice!! Unless you are getting aftermarket wheels and going to simply disable the system.

I can't imaging how a production system could be installed in a fleet of vehicles without training your support technician fleet with the instructions and knowledge to support.

I'm so tired of the f**king thing beeping at me, I don't know what to do!

My swap went perfect, it recognized the new ones right away. I think you need to try another dealer OR insist they replace the central receiver module AND the trigger modules located in 3 of the wheel wells. If they just keep replacing the tire units without addressing the other parts of the system it seems as if they will continue to have no success. The other thing to replace is the EVIC module, but I would try that last. I also don't think it matters how long the techs have been working there, this is a brand new system so nobody has much experience with it.
As it was a theft, I think I would try replacing the trigger modules in the wheel wells first, perhaps one or more of them got damaged while these bastages were ripping the wheels off?

Edit..I just reread your post, did they actually say they have replaced all the things I mentioned?

There are 2 different frequencies used for the modules. One for domestic, and the other for export.
----------------------------------------
Our system is the "Premium"
From the service manual:

TIRE PRESSURE MONITORING - SERVICE INFORMATION
DESCRIPTION
The Tire Pressure Monitoring (TPM) system monitors air pressure in the four road tires (excludes spare). Pressure in the spare tire is not monitored. There are two systems available on this vehicle, a base and a premium. The base
system does not specify how many tires are low or where they are located. The premium system does so.
TPM alerts the driver when tire pressure falls below predetermined thresholds. (Refer to 22 - TIRES/WHEELS/TIRE PRESSURE MONITORING - OPERATION)
The TPM systems are controlled by the Wireless Control Module (WCM), commonly referred to as the Sentry Key Remote Entry Module (SKREEM).
There is a sensor (transmitter) in each of the vehicle’s four road wheels that operates on a 315 MHz radio frequency. Export vehicle sensors operate on a 434 MHz radio frequency.
If a vehicle is equipped with the premium TPM system, transponders located in three of the four wheel wells of the vehicle are used to provide the WCM with the location of the tire pressure sensors on the vehicle. The transponders are located in the left front, right front and right rear wheel wells.
An indicator lamp located in the instrument cluster and, if equipped with the premium TPM system, the Electronic Vehicle Information Center (EVIC) are used to communicate system information.
For further information, refer to the Owners Manual or the appropriate diagnostic information.
OPERATION
The Tire Pressure Monitoring (TPM) system uses radio and sensor technology to monitor tire air pressure levels.
Sensors, mounted to each road wheel as part of the valve stem, transmit an RF signal indicating their individual pressure to a receiver located in the Wireless Control Module (WCM), commonly referred to as the Sentry Key
Remote Entry Module (SKREEM). These transmissions occur approximately once every minute at speeds over 15 mph (24 km/h). The Tire Pressure Monitoring system remains active even if no tire pressure related message is
displayed. The sensors lay dormant (Park Mode), then wake and start transmitting (Drive Mode) when the vehicle first reaches speeds over 15 mph (24 km/h). Once the wheels stop rotating for a period of approximately 20 minutes, the sensors shut down until again awaken. Although not transmitting as when in Drive Mode, while in Park Mode, the sensors still transmit approximately once every 13 hours to let the receiver know air pressure status at that time. Sensors will also transmit when a pressure change of one psi (seven kPa) or more is detected during that period.
If the vehicle is equipped with the premium TPM system, transponders located in three of the four wheel wells of the vehicle are used to provide the WCM with the location of the tire pressure sensors on the vehicle. The transponders are located in the left front, right front and right rear wheel wells. A fourth transponder is not necessary in the remaining wheel well due to the process-of-elimination theory. Once the system knows the location of the first three sensors it assumes the location of the fourth tire pressure sensor is in the left rear tire. For more information, (Refer
to 22 - TIRES/WHEELS/TIRE PRESSURE MONITORING/TRANSPONDER - OPERATION).
If the system detects that the tire pressure in any road tire is going low, beyond the Low Pressure (lamp) ON threshold (see following tables), the TPM system will continuously illuminate an indicator lamp. If equipped with the premium TPM system, a message will be displayed in the instrument cluster. The text message will indicate which tire is low and the display will show all current tire pressures, the low tire will be flashing with its pressure value. This message will be displayed for the rest of the ignition cycle, or until the Low Tire pressure condition has been corrected.
A chime will sound upon initial detection. Once pressure in the suspect tire raises above the Low Pressure (lamp) OFF Threshold, the lamp will go out and the system returns to normal within approximately two minutes time.
If a message center button is pressed, the message is replaced by the new message requested; however, if the Low Tire condition has not been corrected, the Low Tire pressure message will again be displayed.
If a system fault is detected, the indicator lamp will flash on/off for 60 seconds, once every 10 minutes.
-------------------------------------
The TPM wheel sensor I received from Wycoff (see vendors list) was 56053030AB/56053033AA

Check wiring

Just wanted to mention to tell them to double check the wiring. If the wiring is wrong you can keep replacing modules till you are blue in the face and still won't fix the problem. The reason I know is because my dealer had to swap a couple of wires on SKREEM module to get mine to work.

Good luck.

Never mind about the wiring. I just saw that your system was working until tires stolen, not likely wiring.

But can you buy the missing stuff and have it installed and programmed a la the DLR issue which was finally solved? My 05 is sans the TPM system and it bites.

I took delivery two weeks ago. On Monday the temp was 0deg F. The message was two left side tires below safe level, 24psi, since then I have driven 100 miles with the tire pressure display at 27psi on all 4 tires. The system did not reset and I have no idea what to do next. Any suggestions?

You don't mention what the actual tire pressures are (using a regular get out, bend down, apply gauge method). Could be the monitors are reporting actual conditions, in which case you must add some air! Pressure goes down approx. 1 psi for every 10 deg drop in temperature.

Youcould have the tires inflated with nitrogen. It doesn't have the same sensitivity to temperature change as air. It also migrates three times slower than air. It eliminates the problem you described. Check out this website: http://www.whynitrofill.com/benefits.htm

Pardon my ignorance but is the Tire Pressure Monitoring only an option on the '06? I don't recall even getting that choice on the '05.

AFAIK, only 2006. Standard equipment, not an option.

You made a good point, for some reason a digital readout seems like it must be accurate, I forget to confirm. In fact, the pressure displated correlated within one PSI to my good tire gage. The car was delivered with 28 PSI on all 4 tires. When cold it drops to 25 or 26, then returns to 28with use. I did not really want to add much more, the car rides a little harder than I was used to under the best of conditions. I didinflate the two that were in alarm to 35 PSI, and drove about a half hour at highway speed. The alarm did go out, and did not come back on when I equalized all four tires at 30 PSI warm. I hope it was just the extreme cold that affected the system, otherwise I may be looking at the nitrogen option.

Thanks for the feedback. Merry Christmas.
