what does service tpm mean?
I believe it stands for "service Tire Pressure Monitor." At least, other vehicles have a TPMS (Tire Pressure Monitoring System)
Service TPM means "Service Tire Pressure Monitor" The first thing that will need done is to relearn the TPM.The vehicle sounds like it's confused as to the correct location of tire pressure sensors. Whenever the tires are rotated this procedure has to be performed.If that procedure was performed then this could possibly be a faulty TPM sensor but will need scanned to confirm the problem.
My Hummer H3 just had that light come on and than it went out.
