2002 GC w/ Tire Pressure Monitors

[fatfender54]

Recently had the tires rotated during service. After leaving, the overhead console started reading 1 tire High Pressure. I have double checked the tire pressures and all are consistant. Took it back to the garage and they retrained them. OK when I left, once again message came up.

Today I went to the dealer and bought the retraining magnet. I went through the retraining sequence and it said training complete. Took it out for a drive for about 10 miles. Message never came back on. When I got home I turned it off and then back on, message is back.

Does some error code in the computer need flushed???

Van has 96,0000 miles and has never had this problem before, just since last tire rotation.
Any help would be great.


I posted this almost a week ago and no response. Does anybody understand the computer that controls these?
