Tpms

[O Vette]

I got the message "Service the TPMS. The pressure for each tire was XXXX. Brought it in to the dealer and they said the left front sensor was not working and that if one sensor failed the "Service TPMS" message would appear and none of the sensors would work. They replaced the sensor but, had difficulty getting the sensor to "learn." They finally got it to "learn" but, then had trouble with the others. So, they said that it was probably the receiving unit that needs to be replaced and have ordered the part. I'm not sure I have confidence in their diagnosis -we'll see. Now, for my concern. If a sensor is not working it would not report a low pressure condition and, I assume, it would not report a FLAT condition either. I suppose the DIC would give a warning that the sensor is not working and you should check for pressure with a gauge to make sure all the tires have sufficient pressure. This system doesn't seem safe enough to me. You get the "Service TPMS" but you don't know if it is a sensor or the receiver. If you check the tires and find proper pressure, you can continue to drive (presumably to get serice) but, would not know if you suffered a Flat while driving to a service shop. Seems like the system should be able to alert you to a FLAT even if a sensor is not able to report the actual air pressure of a tire. Don't know if I have adequately explained my concern in this message but, there seems to be a serious flaw in the TPMS. Any comments?

Hi there,

Each sensor reads individually and the lack of ONE sensor reading doesnt not disable the others.

The information that you have been given is false. THE ONE sensor will not work, but the others would.

And I would personally be asking for the old parts back.

If your battery condition is low, this problem could also occur.

I would be very suspect and I certainly would find a second opinion.

Assuming that all 4 sensors were "sync'd" originally. If one sensor dies, and you clear the "Service TPMS" message, the pressure reading for that single sensor reverts to "XXXXXX" (instead of 32 LBS), but the remaining 3 sensors will continue to function. (this is just a reiteration of Specialist's answer)

If the dealer tried to go through a re-learn of the sensors and failed, all 4 sensors will read "XXXXXX" because the system clears it's "links" to the TPMSs when you go into TPMS Learn mode.

Specialist can correct me if I'm wrong.

I have different sets of wheels/tires for summer & winter - with 2 full sets of TPMSs, so I go through this process twice a year, as I swap out wheels.

I agree with Specialist, seek a second opinion.

Thanks for the replies. I thought the dealer was incorrect. Yesterday they said the left front was faulty and replaced it. This morning the Vette is reporting pressure for three but not the left rear, so, I don't think it is the sensors (and it cost me around $110). And, I don't thnk it could be the receiver since it is receiving signals from the three other tires. Plus, I had a new AC Delco Professional 86-6yr battery installed at the same time. My guess is that they didn't correctly complete the re-learn process and now I do not think they had their Corvette specialist doing the work. I don't think the sensors were properly learned when new tires were recently installed by the previous owner. I'll post regarding the next round.

Forget to add this to my above post. The dealer said they needed to order a "door lock receiver" as that is were the receiver for the sensors is located. According to the owners manual the receiver for the sensors is located in the instrument panel. I'm having my doubts about this dealer.

Time to check out a local Corvette Club in your area. There must be one close to you. Go to a local cruise night and talk with some other Ceovette owners. You'll find a wealth of knowledge.
I think that your local dealer is doing a number on you.

Good Luck.

Current status is this morning the system was reading three tiires and not the R rear. Drove for about a half hours and suddenly got the Service TPMS and none of the tires were being read. So maybe the dealer is correct and the receive is not working properly. Stay tuned.

Hi there,

I would suggest getting the codes from the RFA module and let us know.

The receiver is NOT behind the dash.

It is located behind the left rear filler panel inside the trunk area.

This module/receiver controls and transmits both tire pressure and KEY FOB data to the DIC/BCM.

Please post the codes and we can assist further.

Allthebest, c4c5

c4c5, thank you. I will pursue the matter and post what I learn.

Current status - getting the "Service TPMS" and the pressure for all tires is XXXX. I pulled the codes from the RFA Module and there were four listed. They are C2100, C2105, C2110 and C2115, which stand for LF, RF, RR and LR TPM Sensor Manfunction. I had the LF sensor replaced last week and for a few days was getting the pressure on three of the sensors. Then suddenly got the "Service TPMS" message. This is 2004 Vette so I don't think the batteries in the sensor are bad (plus I have a new one). I also replaced the battery last week with an AC Delco 86-6yr. Dealer wants to replace the receiver but I am not getting the code B0605 "Receiver Internal Memory Malfunction". Doesn't seem like a sensor programming problem. Could it be a ground problem? This is puzzling. Any ideas?

HI there,

Those codes are for the sensors not being received.

If you have a large speaker magnet, you should try programming them yourself.

A set of rare Earth magnets for a hobby shop (ie. Hobby Lobby) works great, even better than the actual GM programming tool ( which is nothing more than a round magnet ).

The dealer called today to say the Receiver they ordered came in. Went down there to discuss the problem and review the codes. Talked to the Service Manager and mentioned to him the incorrect information I had received from the service-writer regarding the location of the TPMS Receiver and the issue about one sensor being dead and the others not reporting as a result. I also gave him the codes which I obtained with the help from this forum. He regrets the errors. He also mentioned that they had made some other tests on the system last week. (One involved holding a new senson next to a non-reporting sensor to see if they could get a signal.) Anyway, the service manager was quite knowledeable about the Vette systems and I have regained some confidence in them. (BTW he mentioned that the tool they use for the 04's is different from the ones they use on newer Vettes.) So, now I'm going to have a new receiver installed to see if that solves the problem. He did warn that if the new receiver isn't the problem, it just could be that the three other sensors may need replacing. Of course, if the reciever solves it, I will be wondering if I needed a new front left sensor in the first place. Thanks for all the information you guys proviided. I'm new to Vettes and this forum is GREAT.

I just installed all new Chrome Spyder Wheels with the new GY “Supercar” F1 EMT Tires & GM Sensors on my 2006 (Z51) and wasn’t sure what the process was for the car to receive the information from the new sensors, but after bolting the new wheels on & going for a quick spin, everything works great without doing anything. Must be the “learning process” is automatic.

C5 Corvette sensors get programmed with a magnet, I leave it on the lift post to keep it handy, just an ordinary big magnet. The C6 needs a special tool and requires the fob to go to set mode. A quick spin is not enough for the receiver to know that the sensors have changed and it will not automatically learn them.

 

[Oz's 59]

I've been driving it & everything is reading without any problems???

 

[Toms007]

Did you use the sensors from the original wheel? If so, they probably didn't need re-setting. The only thing there, is to check and see if they put them back into the correct wheel location. When I changed out the tires on my 01 we got two switched and the LF sensor was in the LR position and vice versa. So when the readings came through those two were reversed.

 

[Oz's 59]

No, everything was/is brand new. In fact I'm selling the untouched/original factory take-offs. Maybe I just got lucky? :confused

In case anyone is waiting with baited (sp?) breath for the outcome of my Service TPMS problem, here's the latest. Brought the car to the dealer yesterday and after about a half hour they said they had received the wrong part and that a search revealed there were only two in the U.S. They'll let me know when they get one. It seems strange that there would be only two TP/door receivers in the U.S. I suspect that the same receiver may be used in other GM cars, but, who knows. I wait patiently for the next round. Can't imagine what GM will be like if they don't get out from under gov't. ownership. Stay tuned Vette fans.

 

[O Vette]

Here is the latest development. I've waited two weeks for the TP/door receiver to arrive. No go. Called the dealer and they said there are none available in the U.S. dealer network. None. They said they would call GM and see if one can be obtained from the original manufacturer or if some more will be manufactured. The will also ask GM if there is some kind of "work around" for the problem. This seems ridiculous. I don't understand why they can't install the current model of receiver and reprogram the system. I find this very hard to believe!! I think there is a law that requires them to produce parts for cars for 10 years after being produced. In the interim I have to drive around not knowing if I have a flat tire and frequently check the pressure manually . How can they sell a car as expensive as a Corvette and not have parts available? I would like to contact the manufacturer. Does anyone know who that might be?
