2003 Deville "Service Tire Pressure Monitor"
My Deville Tire Pressure Monitor (TPM) worked until a few days ago. The DIC says, "Service Tire Pressure Monitor"
I cannot reset it. I noted that all the tire read good tire pressure except the right rear which read 39 pounds but when
I checked it with a good digital tire pressure guage, it said 33 pounds.
I can put the system into reset and it will beep twice but when I put the magnets on the wheel valve stems, they will
Any ideas about how to fix the TPM system?
