Ok, I have a 2002 Chrysler Town & Country Limited AWD. I have read through all of the threads I can about this and have not found a conclusion for my situation. Here is what’s going on…
I just had new tires put on a couple weeks ago. Prior to having them replaced there was no problem with the TPMS, it was working correctly. Right after having the tires replaced I got the message “service tire system soon”. This message literally came up as I was pulling out of the parking lot of the tire place. I had the tire shop retrain the TPM sensors. They all seem to train correctly but after driving for a minute I got the message back. I have retrained all of the tires myself since and agree that they appear to train correctly but the problem still remains.
At this point I took it in to the local Chrysler dealer and had them run diagnostics on it. They diagnosed that the SKIM was bad and that it was not maintaining the memory from the 4 tire pressure monitor sensors inside the tires. This didn’t seem to make much sense to me since from what I have heard and read the skim is there for anti-theft. Everything I read says the SKIM is what the keys have to be programmed to in order for the car to run with the key. I did not find anything linking the skim to the TPMS.
In any sense, I replaced the SKIM and had the dealer reprogram the keys to it thinking they knew best. Sure enough, I drive away and the message comes back on, “Service Tire System Soon”. At this point I am so frustrated that I don’t know what to do next. The dealer says the next step is to replace the PCM (powertrain control module). At $600 + $100 for programming I am not ready to do this until I get good reason to do so. Everything else is running perfectly fine on the vehicle.
Some side notes… The factory tire size is a 215/65/R16. When I bought the vehicle it had 225/60/R16 tires on it so I replaced them with the same size. The tire pressure tag on the drivers side door says the tires need to be 36 PSI cold. When I checked them tonight they were at 40 PSI. I let pressure out until they were down to 36 PSI and retrained the tires again with the magnet. Same error message, “Service Tire System Soon”.
I am really hoping that someone here can help me figure this out. First, is the SKIM linked in any way to the TPMS? Second, if so, having replaced the SKIM, what might the problem be? Third, could the PCM be bad and only be impacting the TPMS?
Any help would be greatly appreciated. Thanks in advance!
