I am not sure what is going on. I am getting random SERV TPMS messages on my DIC. Sometimes it will show an error whiel I am drving for 5-20 minutes then goes off. I have done the re-learn procedure 3 times and all 4 sensor beep the horn. Do I need to do the spare tire at all? It is a 2007 and the original spare tire is still there.
