We are experiencing a recurring TPMS module fault on our new 2015 Charger RT R&T. This is not to be confused with a low tire pressure warning as the warning light flashes for about 60 seconds then goes solid and then the EVIC displays the Service TPMS Module fault.

The symptoms are 7 days after purchasing the vehicle we got a TPMS module fault. On the EVIC it came up saying to Service the TPMS module. There were tire PSI readings which were accurate. Took it to dealership and they determined it was the TPMS module, although they had to order the part. They cleared the fault and the little tire light and fault was gone. While waiting for the part exactly on the 7th day the fault appeared again. When the part arrived they replaced the module cleared the fault. Today, exactly the 7th day from the module being replaced the same fault appeared. So, I called Chrysler Customer Assistance and they opened a case. I will be calling my local dealer (different than where I bought the car and took it the first 2 times) to have them take a look at it. This has now become a major annoyance, especially on a new car with only 1100 miles. Has anyone else experienced this??
Thanks

Dealership confirmed two codes were produced. C0151D-00 and C1581-00. Used the 9936 Analyzer to read sensors. Checked they were in the correct place and reprogrammed and erased codes. Test drove the car and at least one of the codes returned. Since the TPMS module had already been replaced they called STAR and they recommended a module reset and recheck reset module. Mentioned something about doing some reprogramming. Test drove car about 40 miles and fault codes did not return. So, we'll drive the hell out it and see if the fault comes back in 7 days.

Latest update:
Well, here we are 7 days later and the Service TPMS light came on again!! Every 7 days after they "repair" it and clear the fault the thing faults. I called Chrysler again about this, made another appt. This will now be the 3rd attempt to fix (issue has actually occurred 4 times) this recurring issue. This is getting old. I've only had it a little over 5 weeks and it's been in the shop every other week and it only has 1500 miles on it.

Not sure what else I can do at this point except to allow them to attempt to resolve it this time and once more. I have a case assigned to it and the dealer will be again calling the technical experts. If they can't fix it after the 4th attempt I may have no choice but to start thinking about a lemon law case and seek a replacement. I've documented everything just in case.

Any advice at all is appreciated

So, just to confirm, your Liberty was exhibiting the same Service TPMS symptom every 7 days as my Charger and it was the WCM/SCREEM module? I want to make sure so when I take it in next Tues. I can suggest they investigate whatever the equivalent is in the 2015.
Thanks

My Jeep would Have the TPMS light come on for no reason,then go off,then back on.That is the module that controls the TPMS!

Here's what the WIN module does & TPMS is part of it:

Following are brief descriptions of the systems that the WIN controls.

IGNITION SWITCH
The Wireless Ignition Node (WIN) incorporates an integral ignition switch that consists of four rotary positions with three detent positions and one spring-loaded position. The one extreme clockwise position shall be spring-loaded momentary contact “START” position. When released from the “START” position, the switch shall automatically return to the detent “ON” position. The other position include a detent “ACCESSORY” position and a detent“LOCK” position.

The WIN reads the position of the ignition switch and transmits via vehicle bus. These positions include “LOCK” with ignition key-out, “LOCK” with ignition key-in, “ACCESSORY”, “RUN” and “START”.


SENTRY KEY IMMOBILIZER SYSTEM (SKIS)
Upon failure of proper Sentry Key Immobilizer (SKIS) communication to the Powertrain Control Module, (PCM), the PCM will shut off fuel after two seconds of run time. The engine will not re-crank on the key cycle during which the failure occurred. A full key down sequence must be performed for the engine to crank again (Refer to 08 - Electrical/8Q - Vehicle Theft Security - Operation) .


REMOTE KEYLESS ENTRY (RKE)
The Remote Keyless Entry (RKE), transmitter uses radio frequency signals to communicate with the WIN across can bus.


TIRE PRESSURE MONITORING (TPM)
The Tire Pressure Monitoring (TPM) system uses radio and sensor technology to monitor tire air pressure levels.


REMOTE START WITH/EXTENDED RANGE ANTENNA
Further information concerning the Remote Start System can be located in group 8, Starting System

BRAKE TRANSMISSION SHIFTER INTERLOCK (BTSI)
The Brake Transmission Shifter/Ignition Interlock (BTSI) is controlled by the WIN and prevents the transmission gear shifter from being moved out of PARK without a driver in place.

FOBIK REMOVAL INHIBIT FEATURE
The key removal inhibit solenoid internal to the WIN prevents the FOB with Integrated Key (FOBIK) from being rotated in the ignition switch to the LOCK position for all vehicleswith an automatic transmission unless the transmission shift lever is in the PARK position. The WIN module monitors a hard wired input from a switch intergral to the automatic transmission shifter module to control this feature. The key removal inhibit solenoid is electronically disabled internally by the WIN on vehicles with a manual transmission.

Let me tell you about some dealerships Service,some of the service advisors dont have a clue what they are doing as long as some mechanics.Sometimes I have to tell them how to fix my car!I was at my dealer and saw 2 Service advisors tell a customer who had a Challenger with smart window going down by itself.They told him it was him hitting his remote,when the fix is a TSB!

Thanks. I'll suggest that to them when I take it in next Tues. With this one, once the fault comes on it is always there on every start up and while driving. Once the fault has appeared upon start up the tire light will flash for maybe 10-15 second, then go solid and then a message on the EVIC says Service Tire Pressure Monitoring. The system continues to read the tire pressure accurately, the message goes away, but the little tire symbol fault is always there. The only time the fault doesn't appear is after they have attempted to repair the car and reset the fault/codes. It says off until the 7th day after the fault has been reset. This is what makes me think it's computer/module related. I would think if it was a harness issue or some other event it would appear more random, but like clockwork on the 7th day after reset the fault will appear. Also, it won't appear at start up - only after you have been driving for 15 or so minutes during some point on the 7th day will the Service TPM fault appear.

Im pretty sure its the win module,just cant figure out why they didnt try that.Sometimes dealers service dont make sense on what they do.Chrysler been having trouble for years with their WCM/WIN modules,some had a TSB.Good Luck let us know what happens

Well, a new development. Throughout this whole thing once the fault occurred it has never gone away on it's own. Only the dealership has been able to clear it. So, today I was driving down the road and turned on the Lane Sense feature. I've never used it before. I kept it on for only a very short distance - less than a 1/2 mile. I then turned it off and then to my surprise the Tire Pressure Fault light went off! Now when I start the car the fault hasn't reappeared!! This is getting crazy.

Have you tried something as simple as rebooting the entire system?

Disconnect the battery for a few minutes and then reconnect.

These cars are so highly computerized that sometimes you need to think of them as one. With a computer that is acting squirrelly, the first advice is always to reboot and get the system to start fresh.

Seriously, there is no explanation for the Lane Sense feature being activated influencing the TPMS other than the computer needs to be restarted from cold. It's a bit like a word processing program misbehaving until you open the spreadsheet program and then suddenly things change.

If I had to guess, the TPMS system didn't load properly when first powered at the factory when they put the battery in and turned the system on.

I agree with what you say. I personally haven't pulled the battery cable to reset everything as I'm letting the dealership figure it out. I've only had the car for the better part of 5 weeks so I'm not inclined to monkey with it too much. I believe when it was in last week the dealer contacted STAR and they had them do a module reset. Anyways, when I take it back on Tues. I've got some questions to pose to them about reflashing of the TPMS module, ancillary systems like the WIN module causing a failure to occur, interference from other sources (one of the techs told me a new flash code for the TPMS in vans is coming out due to interference causing TPMS faults), what would cause a failure to occur on the 7th day after resetting and clearing of the fault, etc?

There must be a problem when they did the original programming,thats nothing new,there are tons of TSB from mistakes made from factory,Chrysler not the only one!If they reset the Module and it still happens tells me there no fix until they find the problem with the program,I would ask them to replace module,hopefully its an updated one!

Latest update: Car was back at dealer yesterday. I'm now told there is a new level of TPMS code that was downloaded to my car to address the issue I'm experiencing. I guess we'll see in 7 days.

Good Luck,hope it works,let us know what happens!

Thanks. I'm afraid this "new" code just turns off the message and fault from being displayed (even if it is still faulting):wink3: Anyway, I'll let folks know if it comes back.

My MDH was 1201xx so it falls within the parameters of the TSB.
So, I'm pretty sure they have addressed it but, we'll give it a good couple weeks to see if it comes back.
